Klipper z homing wrong direction I’ll show here what I currently do and try to explain my thoughts, why I do it this way. On my X and Y axis, my endstops are at the maximum position. During this guide, it may The dominant homing direction is determined by the proximity of position_endstop to position_min respectively position_max. So i tried to add two different homing_override for Z and XY. I found where to adjust the Z speed for homing, and the second Z speed for homing (second probe) but it seems that, at least with Klicky, the QGL speed is set somewhere else, it seems to not be influenced by the default (G28) speed setting. By default klipper assumes it's true and changing to false causes the bed to try it's lift towards the nozzle to home. Its better to not enter anything for this parameter, klipper will decide whether or not it should be true based on the above parameters. I use a probe for Z and need the Z_safe_home to z hop during G28. Voron 2. This is not an official Klipper support channel and According to your log you are homing with an endstop for Z, but you also have a BLTouch. Now homing doesn't work anymore when I click "home" in octoprint webinterface. // Direction of endstops when homing; 1=MAX, -1=MIN // :[-1,1] #define X_HOME_DIR -1 #define Y_HOME_DIR -1 X axis homing issue worked with a reflash and no changes. The XYZ axis work fine when homing and manually setting the toolhead position via Klipper. I recently bought a bltouch as an upgrade for my ender 3 pro, wired it all in, checked the wiring twice, and flashed the official firmware for bed levelling and homing from the bigtreetech github, but when it goes to z-home, the probe deploys, lowers and once it hits the bed it stows, but the z-axis continues to move down regardless and grinds on the bed, ive looked online for answers My z-axis is moving in the positive direction, regardless of the inputs I give after homing. Quick calculation: 1 degr on the Z-Motor causes the Belt to move 0,037mm (38,4mm what is the perimeter of the last trolley *1 deg/(360 * 5,2) the 5. So I need to detect the homing state with {% Great Prints? Klipper can help you and your machine produce beautiful prints at a fraction of the time. 000 [0. I disabled retraction on x and y for test and then it completes homing x and y and then tries to go to 150,150 for z-homing but goes in the wrong direction again (-150,-150) which is impossible and I If all the above settings are correct and its still homing in the wrong direction, you can force it to home towards positive by setting the below in the [stepper_y] section. On mine, `G28` will home the X/Y to the back/left and bring the moving print bed all the way to the bottom of the printer. 08 kick_start_time: . 3 KB) Describe your issue: My printer powers up with the left front (0, 0) corner low. When I press home all the motors are turning in the good direction and detect properly the end stops. The default is "x, y, z". While If a motor moves in the wrong direction, add a ! to the enable_pin for that motor. homing_positive_dir: true Everything works perfectly, including the Z Homing. bin), however the bed was rotated 180 degrees, so the origin was in opposite corner, but prints were OK otherwise (but not via Octoprint Basic Information: Printer Model: Enderwire MCU / Printerboards: BTT SKR mini, MF SB2040 klippy (2). How do you invert this? I've tried switching X direction and axis with the interface > tools & utilities. system Closed February 21, 2024, 7:16pm 5. Y-Axis moves correctly when I tell it to move either towards Y-Min or Y-Max. I’d love to have klipper have a backup mode for z. All firmwares measure Z as distance from nozzle to bed, so you have to configure the Z this way. 5mm below nozzle klippy. It's possible the motor wire was installed backward in the electronics box. 500 Z:10. 20 endstop_pin: ^PC3 position_endstop: 320 position_min: 0 position_max: 320 homing_speed: 10 homing_retract_dist: 5 [stepper_z] step_pin: PB3 dir_pin: PB2 enable_pin: !PA5 microsteps: 8 rotation_distance: 8 endstop That guide was incorrect stating that homing towards the min position that x goes left and the bed moves forward. Configure the printer to be able to home the Z axis on its own using "G28 Z". The log file has been engineered to answer common questions the Klipper developers have about the software and its environment (software version, hardware type, configuration, event timing, and hundreds of other questions). The Klipper PROBE_CALIBRATE tool can be used to obtain this value - it will run an automatic probe to measure the probe's Z trigger position and then start a manual probe to obtain the nozzle Z height. log I have tried making the sample retract distance or the lift speed to negative, to correct the movement direction, but klipper won’t accept negative values. The endstop position determines which direction the motors go to get to the endstop. But this one is a bit different, so I'd like to ask you guys if you could point me in the right direction. log and printer.

It's not the fault of the BLTouch. Note that Klipper won't let you move an axis without homing, so you'll have to tell it to home, watch it move, Because of the 3DTouch, at the moment I don’t take care of the Z axis. The probe z_offset will then be calculated from these measurements. Hello, I recently introduced a fourth z axis to my printer (prior it had 3). Z doesnt matter, but would be preferred to be last. It is a good idea to run through these steps after following the steps in the installation document. Like so: ----- When homing X, sometimes it goes the wrong way. log klippy.

Just First time running Klipper and I'm trying to get my config set up. log! If you mean the OctoPrint control window, then go to OctoPrint Settings -> Printer Profiles -> edit -> Axes -> select Invert control for Z. October 31, 2017 09:05AM // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. I can get the X and Y moving in After homing using the Z-probe, the probe tries to retract before the carriage is raised, scraping across the bed, instead of the carriage rising before retraction like the Z-tilt and bed leveling functions do. But to have a more or less good basis test such a config and then if still not working upload the latest klippy. How to set the homing to the corner you want It’s not clear to me what you’re trying to achieve. This is what I use to home my printer with a bltouch for Z in the middle of the bed. #position_min: default from "stepper_z:position_min" section.

Describe your issue: Hello I just got a sonic pad and the homing axis is stuck moving to the same direction regardless if I change the config and I’m not sure why. X Y are now homing, but when I try to home z , the extruder moves to far right , closing the x endstop switch. ADMIN MOD I need help setting up a coreXZ: X and Z commands do the same wrong thing Share Sort by: Best. Your config looks quite similar to mine. Problem with Z direction and homing. 04. Reversing the Y motor (or X motor) causes the Y and X axis motions to be interchanged. The only time I've ever seen this (and it has happened a few times) is directly following a print. My limit switch is mounted on the left. 4; they still perform no homing if promted - is this a normal klipper behaviour if the z-motor did not reach the end stop or should they be moving regardless what's wrong with the z-motor? All Hello all, I have posted this on several other places including the FYSETC github. Logic inversion would solve my issue in a heartbeat but I can’t find any reference anywhere in the vastness of the klipper tuts and discussions on how to do that. No manually-issued home has ever behaved this way. However, with the workaround given above this doesn't work. // Direction of endstops when homing; 1=MAX, -1=MIN // :[-1,1] #define X_HOME_DIR 1 // deltas always home to max #define Y_HOME_DIR 1 #define Z_HOME_DIR 1 //#define I_HOME_DIR -1 I need to do the homing on the Y axis first and then on the Z axis. The bed has 3 belt drive axis and is mounted with 3 pivot points. nothing is triggered during the homing session, however, when the direction is going the wrong way during z homing, i triggered the Z piezo, but nothing happened and it kept going and I had to shut down power or emergency stop. Using the firmware bin files provided by BTT directly. org it would simply smoothly home in the wrong direction and crash. I have my printer configured as a dual x axis carriage. When I went to home Z, via octoprint home z, instead of it going to the z end stop position, the head moved to For information on obtaining the Klipper log file see: https: it should be hopping 10mm in the positive Z direction prior to homing x and y due to the z_hop: option specified in `[safe_z_home]'. I do not get this message if I manually turn the Z lead screw to raise the I downloaded your config file, and I didn't notice anything wrong. 4R Extruder Type Other Cooling Type MOTOR A B wrong direction Basic Information: Printer Model: RatRig legacy V-core 3. BUT the actual nozzle position is X=130 Y=115 Z=6. I am using the original Creality leadscrew which is a T8 4 start and my Z1 and Z2 screws are T8 2 If I invert the direction then my controls for the z axis in manual mode and probably slicing are backwards. The tool takes your stepper_x and stepper_y config and auto-sets your pins. safe_z_height: 2 # default is 2 * z_offset from the "probe:z_offset" section. Been butting my head for the last day on this one do not know where to go next. Need a config. You'll have to add a customized homing section to your config. (Added ! to the diag_pins) When I click to home just X, it will move to homing direction, and crash into the side, even with sensitivity to 255. If homing_positive_dir: true homes to the wrong direction, then try homing_positive_dir: false. h to show that the firmware is set up move the motors to Max when homing. Actual behavior Z-Axies does not move down on Auto-Home or even over the moving menu. cfg file. For the tests I have put axes on slow motion by setting homing_speed: 5. If the Z endstop pin location has been previously defined, be sure to re-follow the process to set the Z endstop pin location (if applicable). I believe that the reason for the gantry crash I experienced in Problem with SHAPER_CALIBRATE & TMC2209s with Sensorless Homing. klipper-gitissuebot I think your definitely fighting a hardware issue as apposed to a klipper issue. I was able to get the Z axis “print” BUT I can’t find where to change the G28 value of the Z axis. I am currently going through the tuning process and trying to set up This document is a reference for options available in the Klipper config file. The position_endstop and the dir_pin. It homes X and Y but not Z with following error: Send: Useful to prevent the z endstop pin sticking to the nozzle and being pulled out of the assembly. 2 with z safe homing defined. I'm not particularly keen on homing the z-axis while there is a print on the bed. 5 MCU / Printerboard: BTT v2 klippy. log file. 000 Recv: ok. when I do the testing with BLTOUCH_Debug as outlined in the klipper bltouch doc, everything works great. 20221122: Previously, with safe_z_home, it was possible that the z_hop after the g28 homing would go in the negative z direction. Instead of going forward and back 10 times it goes forward and forward. 2 Board; all FYSETC stock parts. Klipper3d / klipper Public. But homing after a full power restart causes the Y axis to home in the opposite direction and sensorless homing is ignored for that axis (X works as expected). I am in the middle of building a corexy printer with a moving bed. Basically, I want an order for homing and a dependancy. 1 klippy.

Klipper documentation. Additional Information. issued G28 from Terminal, printer behaved normally, moving to mid-bed and homing with the BlTouch probe. (firmware-bltouch-for-z-homing-ender5. Is the probe supposed to be plugged into the Z-max port? If not, is there an option I might be overlooking in the configuration I sucessfully used klipper before with the same config, then didn't use my printer for several months. This feature is also used when a Z probe is on a different micro-controller than the Z stepper motors. While Voron (inspiration) offers a useful diagram for troubleshooting, I’ve devised a simpler solution. Adjust as necessary Hi, TL;DR, The XY coordinates are ok when homing and when moving via console (klipper), but when performing Z_TILT_ADJUST they are not corresponding and way of. I could change the wiring for my motor but that would still cause the same issue. #define Z_SAFE_HOMING #if ENABLED(Z_SAFE_HOMING) #define Some people face issues with the printer homing in the wrong direction. log I must have a fundamental misunderstanding of how the z_tilt function works.

I’m using the Motor 4 for the second Z stepper and it looks like I can only use the 5 to 8 for Extruders. log (2. Is it hopping the wrong way? If you commend out the '[safe_z_home]' section and attempt to home only x and y, does it still move the z axis? Great Prints? Klipper can help you and your machine produce beautiful prints at a fraction of the time. ADXL345 I need to lift Z before homing X, Y or Z. 000 -10. Refer to Voron Klipper for adjustments to X/Y. I have a FYSETC 2. QGL and mesh use Klicky Probe. Is this a bug or is there a way I can make the behaviour the same as the Z-tilt and Bed Leveling? Safe homing is defined and Z-hop set New build of a Voron 2. Notifications You must be signed in to change notification settings; Fork 5. Most people don't have to invert either X or Y though. I Everything works perfectly, including the Z Homing. I've been trying to find a safe way to home the Z-Axis without using separate GCODE commands. set the alpha_homing_direction, beta_homing_direction and gamma_homing_direction correct to where your endstops are either home_to_min or home_to_max the provided marlin configuration shows // Sets direction of endstops when homing; 1=MAX, -1=MIN #define X_HOME_DIR -1 #define Y_HOME_DIR 1 #define Z_HOME_DIR -1 If I set INVERT_Y_DIR to 1, it doesn't change the Y direction since this is a CoreXY. The homing direction is determined automatically by the end stop position. With this sequence, keep making me home first on the X axis, then on the Y axis and finally on the Z axis. Sorry *I should clarify; the motor function seems smooth, the grinding noise was the result of the bed getting all the way to the bottom and wanting to keep goingI believe it expects to hit the end stop Z sensor, but goes the wrong direction (only during auto home).

Please see attached klippy. Great Prints? Klipper can help you and your machine produce beautiful prints at a fraction of the time. blank_record. That sounds like one of your steppers is moving in the wrong direction. To fix There are two things that can affect motor travel when homing. It seems like it retracts in the wrong direction. g. Check both Z endstops in untriggered and triggered state whether or not they respond properly and equally. This will move Z up 2mm, home X and Y, move X and Y to 100,100, then home Z. I'd like to use the Tap to find and set the actual Z0 position just before a print. 0 (RP2040) + Voron Tap = Only during homing Z axis stepper Z3 goes in wrong direction Majke; Jul 31 The Klipper docs I followed specifically recommend against using sensorless homing for the Z axis as it's not accurate enough to be reliable. ``` Hello, i have a Ender 5 with Klipper. I have tried, swapping the end stop and cable, the stepper motor and cable and driver. Can't t use E0 as my 2nd z-axis driver, because I need the slot for the max31865 sensor. I have two (almost) identical printers (Ender 3 Pro) running Klipper. 4R1 kit with the Spider 2. In the last restart it appears you have sensorless homing enabled, and a safe_z_home defined which is not the Video of wrong movement. The background is that I got a “new” glass printer bed, which is about 2mm thick It’s thicker than the original. Klipper cannot measure any differences in distance that are smaller than the distance of a single microstep. 7 Board, Extruder going in wrong direction, cant update firmware, cant flash new bootloader. It'll go about 1-2 mm to the left, and then immediately go to the right and stay there instead of going to safe z_home coordinates. Installed the Firmware: firmware-ender3-bltouch-for-z-homing. General Discussion. My home location should be on the upper right though so the home I'm having an issue where homing the Y-axis is moving in the wrong direction (Towards Y-Max). cfg (9. Maybe there is a way to Good day. I did try to switch the [stepper_x] and [stepper_y] in my printer. Z axis moves in the wrong direction while homing when recovering a print I just changed the control board in my custom delta printer from an SKR Mini e3 v3 to an SKR 2 and when I try to recover a print the z axis moves moves down instead of up like it should. Moreover, I have to home the xy axes first and then home the z-axis. Jul 15, 2024. 7 board, install it, everything is great, things are much quieter, until I realise the extruder is going in reverse. You are going to have a horrible time calibrating your machine homing from the top. I just need to change the homing direction in the firmware. In your homey. Depending on the reason for that a “working” config might not fix your issue and can introduce new topics. This is good. How can I reverse the direction of the Y axis on a CoreXY? My X axis homing switch is on the left side, and Y homing switch is in the rear. To invert the You can change the orientation of the z control in the UI settings for your web interface and it has nothing to do with how klipper prints. I am using a BLTouch and after the X and Y homing, the BLTouch is not above the bed and can cause quite alot of damage when [homing_override] set_position_z: 5 gcode: G0 Z7 G28 X0 Y0 G0 X100 Y100 G28 Z0. I see this in the default Klipper config from BIQU: The M8P only has 4 heater outputs which leaves an extra stepper This can be used for a second Z stepper, dual_carriage, extruder co-stepper, or other accessory such as an MMU. 000]. log (557.

The minimum safe z height is 3mm. 1. 4k; Star 9. What you actually mean is that generally the origin of the build plate is at the front-left, but this doesn't have to be the homing position. Of course, the CRTouch probe at this point is way off the bed, so I get a lovely grinding noise, followed I have a 2. 9 MB) New install of Klipper using the KIAUH tool, everything is working and I can print functional parts. Immediately after this happened and I grabbed the log, I restarted klipper and did another home and all 3 worked as expected (I didn't touch anything physical). Page 1 of 2 1 2 Next > gunsmoke132 Member. log (695. If you do have a [safe_z_home] section, that section must contain the home_xy_position parameter, as this specifies where the toolhead should move to before homing the Z axis. This plugin provides a new G-code command, STABLE_Z_HOME, which homes Z repeatedly until the Z offset stabilizes. Looking for help with centering the BLTouch homing correctly over the bed center. I am complety new in klipper firmware and I have problem with Z asix, but I dont know what is wrong. if I send G28 X Y, I want home Y, then home X. Thank you both for your help. When X endstop first.

Added UBL, reflashed and the x axis homed the wrong way again. 4 LTS printer. I get the Silent Creality 4. Try inverting the step direction of 2. The default value of 5mm/s is used if Re: Y-axis homing in wrong direction - FIX To fix the homing direction you can try one of two things. Homing the Z towards the nozzle is very common - likely the most common setup. homing_speed: 50 [stepper_z] step_pin: P0. 1 Like. New bulid Voron 2. Core XY system where nozzle is at the top of machine and Z moves up to the nozzle. But i observe tow “strangers thinks” On each case Z axe never move. Scytes New member. G28 should still home every axis, and should probably home Z in the center of the bed after X and Y are homed. 4 KB) In mainsail, trying to “home X”, moves Z down DOWN, “home Z” moves Z axis UP.

Only difference is one is DD, one is Bowden. Im not new to Klipper, but this time after i rebuilt my AnyCubicMegazero into Voron SW I have an issue with the Movement of Y axis. This topic was automatically closed 60 days after the last I've got sensorless running on my enderwire for X and Y. cfg and z_tilt section the Z_TILT_ADJUST macro is acting up. All reactions. The head moves to the nearest position in each case; Homing towards position_max. I need help, I installed a fresh copy of the firmware on my printer, and since then my Y axis wants to home to the front of my printer my endstop is at the back on the Y Min , and if I change directions on Motor and Homing it doesn't matter, when Your response indicates some unfamiliarity with how Klipper works -- the config is stored on the host (usually a Raspberry Pi) that controls the MCU (the board in your printer that runs the motors) -- in a Klipperized printer, the host is the brains, where the config is managed -- the firmware on the MCU just acts as a hardware interface. Drewanmist. cfg set up correctly. 360 [homing_override] axes: yxz set_position_x: 0 set_position_z: 0 gcode: G1 Z10 F600 G1 X10 F600 G28 AND G28 X If G28 all axis, they start moving but Y moves instantly into the wrong direction till X hit the endstop, but sure “fails” (so same behavior like homing X alone, but in wrong order (should be Y,X,Z in my case - but i know i could change with homing override, but haven’t expected a Y movement on X homing). I suspect the Y, Z and Extruder will also be reversed. . Sounds like your motors Change (or reverse the motor connector) if an axis goes the wrong way. On one, I do the PROBE_CALIBRATE thing, do the TESTZ adjustments with a piece of paper, ACCEPT, SAVE_CONFIG and everything is fine - can home it, tell it to move to Z 0, and the nozzle is right at that paper thickness. The z position just is not being corrected. While homing X and Y axes on a cartesian machine can work well, homing the Z axis is generally not accurate enough and may result in an inconsistent first layer height. g file and the Y homing section of homeall. It's a new install of Klipper3d on my old CR-10. So the short answer is this: Move the endstop to the bottom, and home down. GSP. 4. RickStar October 12, 2023, X G90 G0 X20 {% endif %} # Homing of Y {% if home_all or 'Y' in Klipper; Replies 7 Views 814. I have managed to home x and y but when I start the Z homing the gantry go up a bit (probably 10) and stop with this error: Move out of range: -10. After powering on the printer I did: G28 Z_TILT_ADJUST This was the output of the first adjustment: Making the following Z adjustments: stepper_z = -0. The probe and the X IIRC, that same corner was 0,0 when I was printing on Creality's built-in Marlin FW but I switched to Klipper shortly after obtaining the printer over a year ago so I might be wrong. 25 [homing_override SAVE_CONFIG section ‘bltouch’ option ‘z_offset’ conflicts with included value Background This can happen when Klipper tries to update the z_offset after calibrating the bed and issuing the SAVE_CONFIG command Reasons The bltouch config section has been removed from printer. This support is referred to as "multi-mcu homing". I tried thi Basic Information: Printer Model: Custom build bed slinger based on Ender 3 (but so heavily modified to effectively be a new machine) MCU / Printerboard: SKR E3 Mini v3 klippy. M. Check Klipper out on discord, discourse, or Klipper3d. The Z is currently moving to 0, which is wrong in this case because it should be Z=2 It seems it is just moving into the wrong direction when homing. And Auto-Home should success. In Configuration. My printer is set up so that it cannot home X until after it homes Y. This will reverse the direction of the stepper motor. bin. klippy. 5 ; trigger point is 9. After that, i try to make G28 homing. SensorLess Homing goes wrong I need your help for the homing. my nozzle goes to 0,0 and then lowers on the Z axis. Ender 5 pro. but when I try and use Z_Tilt stepper Z2 goes the wrong direction. Thread starter Scytes; Start date Aug 7, 2023; S. 038129 Then 2 more The z_offset is the distance between the nozzle and bed when the probe triggers. cfg Restarted moonraker Restarted klipper Re Further, sensorless homing might not be accurate enough for your printer. , Manual leveling - Klipper documentation. cfg. Here is the homing direction settings in marlin configuration. second_homing_speed: 10. 21 To me it looks like you are overextruding and/or your rotationdistance is wrong for your z axis, since it looks like the top layer is inside the cube, thus This document is a reference for options available in the Klipper config file. The fine tuning is done with the Z_ENDSTOP_CALIBRATE Klipper supports a mechanism for homing with an endstop attached to one micro-controller while its stepper motors are on a different micro-controller. And this is part of my printer. X; Replies 3 Views 2K. I’m want my probe to move to the middle of the bed for “safe z homing” but right now I can’t seem to figure out what I am doing wrong. 2 KB) klippy. It's done by using some macros and a [homing_override] in the config files. # It is also possible to negate an axis if the accelerometer # direction is reversed (eg, "x, z, -y"). CoreXY Homing is wrong direction. There will be a line which is showing a dir_pin, if there is an '!' before the pin name like this: dir_pin !PB6 Remove the '!' sign. If anything is updated in the printer configuration file, save the file and restart Klipper using FIRMWARE_RESTART. something went wrong. 1 500x500 printer. Only significant difference is: homing_positive_dir: true in [stepper_x], which should probably be in your config- atm your toolhead would be moving to the left while homing, but think that the position is 220 (position_endstop:220) when all the way left 'homed'- correct? Hello everyone, unfortunately I can’t find where I can adjust the homing coordinates. Nothing wrong with X or Z. // - If stepper drivers time out, it will need X and Y homing again before Z homing. So I have been a lil bit of a nightmare. After a few iterations I get the message below. Posted by GSP . This document provides a list of steps to help confirm the pin settings in the Klipper printer. ADXL345 Sounds for me that the Z homing is not successful hence the Z1 stepper seems to move away from the endstop even if it might be the wrong direction. Same with Y. Been tempted by klipper for a while, need to get a bunch of prints done before though. 200 heater: heater_bed [fan] pin: PC6 # "FAN0" cycle_time: . Touch mode, triggered when its pressed, open when not, pin down, etc #still not homing endstop_pin: probe:z_virtual_endstop #probe:z_virtual_endstop position_min: -5 #position_endstop: 0 Does it move to the wrong direction. When I print, it homes to the zero position and then I have an issue with the stepper motors direction on all axis. 0 [stepper_z] step_pin: PD7 dir_pin: PD6 enable_pin: !PF10 it goes through what to do if the axes move in the wrong direction. running Calibrate_Z tests the difference between nozzle plunge and Klicky switch plunge on the endstop. I can move axis X0,X1 and Y manually after homing. With the new motor wires (Blue, yellow, red green) you can simply unplug it in and turn it around so the red wire is on the left. I upgraded to Klicky probe, sensorless homing (just like my ratrigs) and running the latest klipper version. Apr 23, 2023. Klipper What gets me is that not only does the sensorless homing behave as expected, the homing process does as well. F. Homing is done Z first, the gantry moves to the top, then X and Y are homed and it works just fine. Klipper homes in the relation between position_min / position_max and the respective position_endstop. 5: 128: September 8, 2024 Seems like there must be and easier way than commenting out >150 lines of macros. If The sign is not there, add it just before the pin name. How do I resolve this issue? The intended homing procedure and screws_tilt-adjust is as follows: #1 The bed, x and y axis are homed, using sensor-less homing. 000 E:0. Discussion in 'Troubleshooting' started by gunsmoke132, Apr 18, 2018. This is not an official Klipper support channel and poorly moderated so ymmv. Users that wish to converge to the z homing position # should set this to 0. Azertime. fix for this Klipper error: Invalid homing_positive_dir / position_endstop in ‘stepper_x’ Thanks in advance. Problem. I ran STEPPER_BUZZ STEPPER=stepper_x/y/z and see that the x axis is moving left, y axis is moving towards me, and z axis up. g ; called to home all axes G91 ; relative positioning G21 ; Set units to mm Here's my override for "HOME Y before X" allows individual homing as well as the "optional: O" flag don't know if it's possible to run "G28 XY" or just "G28 X Y" Seems they need to be separated to process correctly due to "VALUE=" Solved y axis moving wrong way while homing. Now, a z_hop is performed after g28 only if it results in a positive hop, mirroring the behavior of the z_hop that occurs before the g28 homing. 021311 stepper_z1 = -0. bin; Press Auto-Home; Expected behavior Z-Axis should move down also without the EndStop with firmware-ender3-bltouch-for-z-homing. Of course, your position_endstop must be in a way to stop the axis before it hits the bed. Consider that a bed dropper and flying gantry probably want different actions when you press 'up' I'm having trouble with a quirk in my firmware where the Z axis when told to home to a min endstop, homes in the + direction. I THINK I have everything in printer. As it says in the comment, you can either change the INVERT_Z_DIR parameter or flip the connector of the stepper motor on the board. im having the problem that the corexz movements dont happen like they should. 000 10. log (1. but as you can see, I have all mine set to min, and previous in configuration. Also, any CoreXY Homing is wrong direction. The probe needle lowers, and instead of moving down to the bed, it moves up, away from it. cfg Potential solutions Revert the When I run the home function however my Z axis and Y axis perform as expected but the X runs to the right hand side. 11 enable_pin: !P0. 500 Y:117. B. Homing a delta printer sensorless is not advisable due to missing accuracy. g, you need to move the Y axis in the +Y direction. Klipper bl touch z off set calibration has Go to the printer. Welcome! Change (or reverse the motor connector) if an axis goes the wrong way. I already checked the wiring multiple times and the motors I am going in circles trying to set my X & Y “origin” to the front left corner as my “0,0” and Position_Min & Position_Max. I have the probe plugged into the Z-min port. org Stop Z homing to resume failed print hi so ive completed the config checks and all seems to be ok i can buzz all of the steppers and they work fine i have tried the ! in front of the pin and if i move the bed to trigger the endstop then it tries to move the wrong way and if i move the bed to the middle and run home it does the same thing just moves away from the trigger slowly until it reaches the opposite end Maybe your axis are out of reference, klipper does not print with disabled steppers if you have no homing in print gcode @kevin is it possible to change configuration to print without reference? For laser engraving and Hi everybody, I’m wondering what the best strategy in using the capabilities of Klipper’s bed leveling tools might be. config file and find the Z stepper motor which is turning the wrong way. A. cfg so that Klipper knows to use it. Homing to the Z max is bad. So either printer. Both have a BLTouch. Ender 6 Triple Z tile moves in the wrong direction but Z Home is correct on all 3 steppers I actually do have homing_positive_dir: true under my Z stepper section but didn't include it above since it seemed redundant. I'm new to klipper and still building out my printer config so bear with me. toolhead. 0. I used the first homing_override until today (capacitive probe), but now i want that the nozzle move Z+15 when G28 X0 Y0. In my case since my print bed moves rather than the extruder gantry, I need to invert the Z axis for this to behave itself in the Control tab's up/down buttons. Depending on this relation, the direction of homing is chosen. cfg Configure your printer to use the probe as the Z home switch. I It did not look like there was a Klipper log file attached to this ticket. Open comment sort options 0. Configuration checks¶. After adding the fourth z to my printer. The log has dozens of restarts with numerous errors. 4 with four Z endstops at the high end, and a Tap. if I send G28 Z Y, I want home Y, then home Z. Y axis homing in the wrong direction. First homing attempt X-stepper is going the wrong direction. After I home Z, I cannot move the axis manually. edjrwinnt opened this issue Mar 4, 2020 · 5 comments I will try the hardwire route but don't understand why this way will not work. cfg When issuing G28, my printer no longer I inverted the diag pins for TMC Driver on X and Y, and QUERY_ENDSTOPS in klipper has X, Y an Z as 'open' prior to homing. homed_axes needs to be updated correctly when working with sensorless homing or there needs to be a way to update it from the macro code. My f6 worked great out of the box with klipper (2208 aside) i had trouble getting things moving in the right direction (reversed motor connection/homing direction) but I always had linear movement, is it possible one of the motors is skipping and not physically As my printer homes X first then Y I’m trying to find a way that after X homes is there a way for me to move X 20mm before it starts to ho I have a filament cutter at the front of my printer I want to avoid when homing. I use a Euclid probe but if something goes wrong I’d like to use sensor less z to auto pull up past a certain point of step misses. ADXL345 Sineos thanks for the fast reply, the issue I’m having is that when trying to set the position_endstop to a negative number or the position min, it gives me the unable to infer homing_positive_dir warning, so I was wondering if I have to specify in the config which direction is positive using the homing_positive_dir to true to fix that. zip (315. log (996. 2 is the gear ratio of the Z-gear). I tried plugging in both z-motors separately (ZAM + ZBM), and wired parallel like shown in the picture. This is useful if you have a printer which homes by pushing the nozzle against the Z endstop, where any plastic on or oozing from the nozzle can affect the Z offset and hence cause variation in the height of your first layer. I home it, then do a Z_TILT_ADJUST. My bed goes to full extents when power off or klipper disconnect/restart. Basic Information: Printer Model: Custom MCU / Printerboard: Manta M8p klippy. Can I correct this in the printer config ? So far the bed and extruder heat controls work. cfg file but it still moves the wrong axis just in the opposite direction. But when I ask the motors to move they stil try to go on the end Being new to Klipper I wasn't sure if there was just one global setting to "make Z axis home in the opposite direction" or if each stepper needed to be manually adjusted. $\begingroup$ Sorry Mick, bit this answer is wrong, you can have the endstops at every side, so at the max or at the min position, as long as you tell the printer where the endstop is in firmware. 6 MB) So I have an issue getting the X axis to realize which way it’s supposed to go. 20210313: Klipper's support for micro-controllers that communicate Great Prints? Klipper can help you and your machine produce beautiful prints at a fraction of the time. See here for a way to confirm directions using stepper buzz https: Thanks, made the change. When I use stepper buzz to verify motor wring most of them work fine but my Z doesn’t buzz the same way. Recomplied and flashed, no changes x axis is working again. I’m trying to figure out why my bed mesh is not working and currently making sure I understand how Z_TILT_ADJUST works. whenever I try to home the y-axis it moves the opposite way its supposed to and makes a grinding noise My problem is that the Z axis moves in the wrong direction while homing. Again, it is your understanding that is wrong. The absolute z position in mm to move to before moving to the next position. I’d like to invite you to If you enabled Z_SAFE_HOMING, then automatically the printer homes Z at the middle of the build plate, if the bed size dimensions are correctly defined (in your case X_BED_SIZE and X_BED_SIZE should be defined as 300). hey guys, i have just built my ender switchwire and im using the stock creality board, im pretty familiar with klipper because i have been running it on the printer before i built the switchwire. bldxvaui pfxb unokg pqjqe xdzyya blwirfvw uty lulrnzd mexoi gwxl
