PLEASE help me resolve the constant "Filament Stuck" errors
Hi guys, nice to meet the community. Let me introduce myself for some background.This is my first Prusa Machine but I have been printing for a while now and have a small farm and know my way around printers - Not a custom Voron level but I can fix most issues on my printers.
I have had the Prusa XL Multitool for about a month, it costs about 4 months worth of salary where I live so I spent quite a lot expecting at least a decent experience from Prusa. So far I have been very, very dissapointed. 2 defective thermistors and 1 filament sensor cable out of the box (quality control I guess?) But those are minor compared to the constant filament stuck issues i keep having with it especially but not limited to multi color/multi material printing.I have to baby sit the printer and fix that every 1 to 5 layers depending on my luck. absolutely frustrating. At this point I can use 1 toolhead and just manualy change the filament myself.
I have printed those PTFE Guides to help the filament feed streight with 0 change when it comes to the issue, although it looks kinda cool in orange and black.
I contacted Chat support and they have been beyond useless. The lady I got assigned to was gaslighting me that I have to use the default Prusa filament settings for Input shaping profile because its "too fast" and the temperature there is 220 instead of my 215c. I tried to explain that although the speed seems high to her its really not that fast and I have set my filament profile to 7.5 Volumetric which is far less than the Default 15 so my speeds are actually lower and even if they were not a 5c difference in that speed range (around 100m/s on average) wont make any difference. She told me that "I need to do it or the troubleshooting can not continue" Well as you might have guessed I did it test with Default profile and other than the printer printing faster there were absolutely no change when it comes to the fillament stuck issue.
Please help me fix this issue!The printer is literally collecting dust at the moment and I am considering returning it because I cant stay and baby sit it while operating 12 other machines...
RE: PLEASE help me resolve the constant "Filament Stuck" errors
My experience with support was frustrating as well. A defective thermistor as well. I'm remote and parts take a long time getting here. I was having a lot of random problems and stuck filament happened a lot. I solved it with ferrites on the wires from both sides into the controller and on the controller up front as well as power supply. I think it is very sensitive to EMI and if you are around all those printers there's plenty of EMI. We never actually could find any stuck filament. It reminded me of a problem we were having with a big industrial CNC router in the past and solved it with ferrites. NO issues like that since until a thermistor died. I've got to say that compared to our experiences with our old MK3S+ printers the XL has been frustrating. When it's working it's fantastic. But the issues lead me to take it out of our production. Hoping once the thermistor arrives it behaves again and I can put it back to work. I can't waste weeks of time with it again. Chat support was such a pain I went to email with a 4 day lag and limited success with them. Prusa has a potentially great machine but they need to up their game with it.
