New to the X1C but not new to 3D printing. I use my X1C solely for printing ABS and own a dozen Mk3s for PETG. I’ve been very impressed with the X1C so far, but this new issue is concerning…
I have printed approx 3kg of ABS so far using mostly stock settings. This issue has cropped up in the last half a dozen prints.
Basically, in certain directions, the top surface infill does not reach the perimeter walls and so leaves a gap about 0.5-0.8mm between the two features.
I’m inclined to think this is a belt tension issue, but thought I would ask here first in case its a known issue. I have confirmed that circular geometry is indeed circular on the X/Y axis, so perhaps its not a belt issue?
Excuse my poor photos, but you can see where the infill is not meeting the perimeters. It will do this on straight edges too.
After printing 3kg of ABS I would suggest cleaning the carbon rods and retighten the belts, followed by a new calibration run. If you’re used to 3d printer maintenance, this is a snap and takes not more than 30min when doing it the first time. I did this after printing a big spool full of ASA when suddenly circles went oval.
The procedure is described in the wiki.
Good luck.
Thanks - This was going to be my first point of call, so it’s refreshing to hear you suggest the same thing - I just hope it does sort the issue as it does seem to be getting a little bit worse with every print.
I’ve become too used to these Prusas just printing dozens of kilos of filament with absolutely zero maintenance, albeit it much more slowly compared with the X1C. I’m starting to think that with the high speed comes a high level of maintenance? I’m fine with that, just want to be prepared for it.
Having re-tensioned the belts and cleaning the carbon rods as per the 2x offcial BL videos, the problem unfortunately still exists and is getting marginally more worse. I have examined the issue closely over the past week and I’m fairly confident the issue is under extrusion - It appears the necessary line width not being maintained whenever the nozzle quickly changes direction.
I am going to attempt to clean the hot end later today and run some more test prints (with known good gcode that had previously printed nicely) after to see if there is an improvement.
