I sliced it with cura4. Hello and welcome to Protips! One can determine the severity of the stringing issue by printing a stringing test print or stringing tower. 5-2mm. One of the unexpected benefits of going to a direct-drive is that my stringing dropped to near zero. That's with a direct drive and it almost always depends on what temp you print at, and what material. Stringing is, without a doubt, one of the most widespread issues in the world of 3D printing, with every 3D printing enthusiast most likely coming across the problem at least once in their 3D printing journey, where the I’ve printed a retraction distance tower for petg, its printed at 235 degrees and direct drive, retraction speed is 45 mm/s. 7 mm at 40 mm/s. 5 to 3mm and from 10 to 80mm/s speed), the tower was just way too stringy. The top was just as stringy but the strings broke when I took it off the plate. Printing this model can help determine whether adjustments to certain print settings can alleviate the problem. The original settings were 8 mm distance and can't remember the speed. 5- Speed 50. test the right retraction distance and retraction speed. The retraction speed doesn’t affect stringing so much, 30mm/s and 90mm/s give no big difference on stringing issues. 5mm ( I have a direct drive extruder, not bowden tube) and although it's not stringing, getting a lot of "zits" on the surface I've been obsessively trying to reduce stringing, and so after doing some research, I performed 18 stringing tests by improving each iteration. Direct drive - Start at 0. he fought with it for a while. Heres my set-up: E3V2 with stock hotend, 0. Cancel, adjust settings and try again. Try re-applying thermal paste on the threads between the heatbreak and the heatsink. 0): Just installed direct drive and attempting to fix stringing. 16 votes, 45 comments. 6 and 0. I am not quite sure why multiple filaments give me this issue with Discover the secrets of 3D printing retraction in this guide. The pic attached is the best I could get it on PLA. Still had stringing, i think that direct drive reduces the retraction distance needed. 5-1mm and a Retraction Speed that’s also in the 35 – 45mm/s range. I know the optimal temperature to be 185 Degrees and I have left that as is for now. That documentation was probably written for the Mk3 printer. The printer is a Mingda Magician X. It doesn’t fix it Running a direct drive now and down to 1mm @35mm/s or less retraction distance. I print my PLA with 0. 6mm with speed 30mm/s are ideal. 1 Sunlu Pla+ After that, I went to test stringing (because, that's half of why I went with direct drive!). 2 before I converted (IIRC). When I was printing with PLA I turned mine up from . GCode file directly, then the printer will use the GCode A direct drive extruder will have a lower distance as it needs to pull back a small amount of filament. The S1s have direct drive extruders which supposedly require a distance around . 5-2mm and RS of 25-60mm. The creality ender 3 bowden style extruders, where they have this long tube, where the filament's forced through, generally need a much higher amount of retraction than direct drive extruders. While 5. This simple STL model (such as this) is purposely designed to showcase stringing. I have a Sovol SV01 printer and it prints eSUN PLA and eSUN PETG perfectly fine using Cura. Stringing is affected/caused by more factors than just the retraction settings. Because the nozzle is bigger and there's more However, it is incumbent to understand the issue of stringing 3D printing before you can try to resolve it. 5mm increments per level so it finished with 2. 5mm distance and 45-50 mm/s speed. When I try my eSUN TPU 95A however, I get large blobs at a distance next to the walls. 0 mm distance in Cura. Hence the retraction distance being 2 mm. With the Ender 3 S1 and its direct drive extruder, you can This is substantially higher given that I have a Micro-Swiss Direct Drive extruder and a Micro-Swiss all-metal hot-end, which recommend somewhere between . A dialog box will prompt you to choose between a Direct Drive Extruder (DDE) or a Bowden setup, as the test adjusts based on the type of extruder you have. When I switch to . 5mm@60mm/s for retract, and runs his nozzle temp about 5c higher than before with it Help with Stringing (Ender 3v2 with Direct Drive) Fix My Print Hey Everyone! I'm hoping to get a little help with my prints. This helps prevent oozing and ensures that the filament only extrudes when the nozzle reaches the next What would you think is my best approach to handle this and is there a way to test this if the stringing test shows no stringing but others do? Printer and settings: Mingda Magician X2 (Direct drive) PrusaSlicer 2. I have already performed an esteps and flow calibration. But for Bowden tube 3D printers, we still need to test it and see if there are any differences. I have tried a few temp towers and oddly enough the stringing isn’t so bad at higher temps closer to 200. This is Amazon Basics PETG. Mosquito. try doing a simple traction test instead of the towers So, excited I had cracked the code I updated my settings to 0. While adjusting the retraction distance, increase or decrease it in small increments to get the best suitable length because it varies depending on the type of filament you are using. 4mm at 25mm/s as a sanity check. [Matched his exact settings from the Print this first without any retraction, this will print with a horrible stringing effect. This is a simple 3D model in STL format , usually consisting of two vertical towers. In contrast, a Bowden extrusion system will have higher distance values ranging between 5-7 mm. 3-0. It's a brand new box of filament, 2. 0mm. Now with I used the following parameters to test for the best retraction speed and distance for the filament I’m planning on using. I can get some fairly blob/string free prints depending on the model. For reference I us 0. Move speed / acceleration. At least, no stringing. thats an awful lot of retraction for direct drive. On the other hand, in the case of a direct drive extruder, the extruder and the nozzle are practically right next to each other, meaning the usage of a smaller Retraction Distance value is enough for the retraction to achieve the I have a direct drive setup with linear advance so instead of messing with retraction/stringing I do a k factor calibration. I bought a spool of Overture TPU to try it out. The default values for start PA, end PA, and PA step should work fine for most tests. I'm betting yours was run 0-2. Then work your way up and activate as much retraction as needed until both towers are perfectly printed without any strings between them. Stringing on string calibration prints, but barely any on real prints. 7mm and stays very consistent from there all the way up to 4mm retraction distance. , Bowden vs. I'd like to push the limits and print something detailed like a tabletop mini (scaled up 200% I’m having troubles with stringing on my Ender 3 v2. Pictured above are two retraction tests I printed. I'm not at all familiar with S3D but in Slic3r PE it's under "cooling" for filament settings and is called "Slow down print if layer is below" (default 20 seconds). I’m printing with ColorFabb PLA LW HT fillament. I think I ran 7. 0-3. He runs the MS-DD at 1. The issue is that through all the parameters above, I am getting nasty The tower pictured is most likely for a direct drive setup, which run very low retraction. The original bowden setup TPU is not so hard to print if you know how to deal with it. This time with a Ceality CR-10 Max. I used Micro Swiss's suggested 1. I recommend you lower your extruder temperature at least 5, maybe 10 degrees. Then the extruder started clicking like I had a clog or it was binding. It's the best mod you can do to your Ender. I'm not sure how much retraction you can do on the Mini I use 1. 20 is for Bowden tubes, even that's high. You shouldn't have anywhere near that much retraction on a direct drive like the MK3 Stringing in the nozzle might be caused by a heat dissipation issue in the nozzle. In this v 2. From a guide on 3dp, for pla my retraction is 6mm retraction distance and 25mm/s I just started this same test on 4mm retraction with 200 heat and it's actually looking a tiny bit cleaner. 5 mm) for this setting if you have a direct drive extruder configuration (e. The original location of On my direct drive printers I print even lower with eSUN PLA+ around 204-205. 6, I'm usually around 6. Temps (tested PLA) are set at 210C and fan speed 100%. 7, 4, 6, 11 mm) and speeds basically the same as https://www. Lower the high printing temperature. 3 to 0.

Here's a print I made of this stringing test stl file I needed to work my way up to 2mm reaction @ 40mm/sec to get that last little bit of stringing to go away. Retraction settings instruct the feeder to pull the filament back slightly when the extruder moves across empty spaces. I’m running into stringing problems, and the calibration program gives me no solution. Most direct-drive extruders only require a retraction distance of 0. I also installed a cooling upgrade/change at the same time (details also below I'm using firmware retraction, 1mm at 25mm/s, but with the basic stringing test from the plugin in Cura I'm getting little spikes on the seam and strings between the posts. Here are my settings. I also printed linear advance tower and calibrated that, i checked the Ender 3 v2 with new direct drive microswiss setup. To quickly recap, we can say that a retraction speed of 45 mm/s, a retraction distance of 5 mm (2 mm for direct-drive extruders), and a retraction minimum travel value of 1. After sticking a direct drive onto my Ender 3, I have found that even with a calibrated k value of . 0 mm I never use retract at layer change. Reducing the print speed and increasing the travel speed. Still stringing. With my e3d Hemera direct drive I should have retraction set to . 5. Recalibrated Esteps and linear advance and it's stringing. The recommended retract distance is 6mm. Ever since I got the Ender 3 I have had issues with Direct drive only needs a retraction of between 0.

I'm getting really bad stringing on every print, to the point where it's pretty much A retraction test is a calibration process used to reduce or eliminate stringing and oozing issues during 3D printing. retractions between 1. I did some googling but I can't seem to fix the excessive stringing of a new spool of eSUN PLA+. 1. 5 and 1. I have a titan aero direct drive extruder. But get a better test, or test in sections. If you're using the normal Bowden system, it's possible 6. 05, and retraction speeds 10 to 80 mm/s. If you have a direct drive When doing direct drives you really only need to test at most 0-0. It can always be better! When you are making 3D prints to sell, less cleanup = more time. I started to have less stringing at 3mm but it's just ridiculously high for a direct drive setup. Also that seems like a lot of retraction for a direct drive installation, especially seems a clog risk with an all metal hotend and pla. If Don't forget to do a 3D printer stringing test after setting the printer. I’ve been okay with PLA, but all of my PETG prints so far have had issues with stringing, so I spent half a day just doing test prints and adjusting retraction distance, retraction speeds and travel speeds. Regards Retraction is the key to reducing stringing. I do notice that quite a bit of filament leaks out of the end of the nozzle as it reaches print temps but before the print I recently upgraded my Ender 3 Pro with a direct drive kit, primarily so I can print soft materials like TPU. It supports the Microswiss All Metal Hotend, Stock MK8 and the Slice Eng. 4 mm Retraction Distance using a direct drive extruder. What could be the Examine your tower and look to find the smoothest print (less stringing) and match that to the information in your generated G-Code. 4. 0): Here are the settings (I'm using Cura 4. Step 2 – Print a Stringing Test Load a stringing test STL file into your For example, ABS and PLA are suitable for a speed of 40 to 60 millimeters per second and a pullback distance of 0. In my case I found for the Geeetech A20M a 6mm Retraction distance with a speed of 40mm/s One of the most effective ways to fix 3D printing stringing is by enabling retraction. In many cases, following this tuning method is not necessary. Calibrated esteps as well as flow rate and tried retraction from 1-5mm and I’m still getting constant stringing. It involves systematically testing various combinations of retraction distance and speed to find the optimal settings Direct drive printers, on the other hand, usually need only 1-3 mm. What would be a good baseline to start with? What would be a good baseline to start with? Using a mostly stock ender 3 pro (steel + pei bed and skr mini e3 v2 being the main upgrades). I recently did a direct-drive conversion with the Sprite Extruder Pro, and I couldn’t be happier except when it comes to printing with a 1mm nozzle.

Bowden extruders, however So I printed a Direct Drive mount for my Ender 3 Pro a week or so and have been struggling considerably with stringing (PETG as well as PLA). [watched CHEP video 3) Retraction 6 - Speed 25. This value will slightly affect your print time, increasing or decreasing how long it takes for the filament to retract before a movement, and plays a role in eliminating stringing from your prints. 5mm to 1mm for direct drive extruders. I tried printing a stringing test and i got the best results with 4mm retraction distance and 40 mm/s retraction speed, but there still are blobs and strings. You should be doing tests and calibrating for a much lower retraction distance. Reply reply Also i have a Capricorn bowden tube. 5 to 3. 2 layer and same thing ) idk how people here recommend up to 6mm and higher retraction distance on a direct drive (filament going directly into the print head) system the stringing that you have can you also come from filament that is wet, it melt on the nozzle and the retract doesnt retract all of the filament, then the nozzle moves to the new position and the left over filament gets "glued" somewhere. (Image source: Thingiverse, s3sebastian) Stringing exists due to melted material oozing when FDM 3D printing nozzle moves from the printed area to the unprinted, causing a reduction in print quality. Keep the nozzle clean. 5 now, but I have a In today's video, we will show you how to upgrade your PrintMill from a bowden tube to a direct drive, using 3D printed parts. Cleaning or changing your nozzle is suggested to be done when you observe the layer of residue. The whole reason i bought a DD, is because i would be able to printer TPU ' faster' and with less hassle. I use 0. ender 3v2 with Micro Swiss NG direct drive and hot end.
