X1C AMS Slot 4 issues with clogging Nozzle and Extruder

[vladimir.minkov]

Yes i was annoyed that after spending 2000EU ( here cost that much with some extra plates) to realize that my old printer is doing nicer prints most of the time for fraction of the cost , but X1C has its good points as well especially the AMS

Especially for PLA and PETG , it took months to get to the same quality and same mechanical tolerances with out issues on the X1C

@lordtime your issue is most likely related to one of the following

• do not think it is the slot but check if the roll is free if you did offset the roll it will have resistance and causing issues , just with hand rotate forward backwards the roll in the AMS there should be no resistance, and if it does shift it to the left in the same slot
• PETG flow - too high for X1C needs to be measured(calibrated) and reduced bit lower 1-2%, my filament measured is 0.99-1.0 and i use 0.97 to 0.98
• PETG PA(K) - too low most PETG is around 0.05 , but i measured it in my one is around 0.05 and i use 0.042-0.045 , but lower more likely for clogs higher the corners may not be sharp enough - Auto dynamic flow(PA/K) is good for nothing in X1C
• speed too high - max speed for PETG is 140-150mm/S and i recommend bellow 120 or at least bellow 120 for external walls and surface , for good print 70mm/S, also X1C acceleration reduced to 4000mm/s2 helps
• Filament wet - new filament out of the box can be wet
• printing directly from Makerworld is a bad idea as different filament different settings and different people , so suggest import objects only and use you confirmed PETG print settings mainly around the filament , the rest only if you trust the Author
• cooling parameters less likely but check
• warping - if detaches from the plate ?
• unlikely by not impossible HW path related

Additional info for the latest test a and print settings in a test model shared here
The original author created a test model and inside i shared my print settings for PETG and the Author added his successful print settings as well after that so do not use the first publish author as this was the problematic once

Quality issue with right top slope of hexagonal holes

I did a quick test print with a test model. [IMG20240425000554_1] On the left is the standard settings and on the right is modified based on vladimir’s first comment. Speed: Outer wall: 70 Inner wall: 200 Seam position: back The results seem to be identical. @vladimir.minkov Later, I will try some of your suggestions in your new comment. I have uploaded this test model here along with the 3mf used. Note that I printed at 50% scale to keep it short.
