Hello, I have 4 X1C printers and my first 2 X1C printers include, 1 Kickstarter printer and the 2nd I bought about 3 months later. the 3rd and 4th I bought, maybe 4 and 5 months later.
-
The 2nd printer started giving me the z-binding issue on the outer walls. I tried all the general maintenance following the wiki (Clean z rods, re-grease, clean carbon x/y rods, retention belts) and that did not work
– 4-5 weeks later the 1st printer started to give me the same exact issues. -
I notice when I print 1 pc its perfectly fine, when printing multiple pcs on the bed then the problem occurs.
-
Support suggested I clean all the idle pulley silver wheels on x/y axis and I also included the z axis. They did indeed have some build up that looked like compressed pimples of rubber build up.
-
I clean all that gunk from all of the silver idle pulleys re-ran another test of multiple pc and as you can see in the picture for reference no fix.
-
Support suggests that it may need new x/y belts replacements. It’s interesting that they didn’t suggest no z belts replacements.
-
This is where I am stuck
-
Please read this other persons post as they have the same issue to the T, they just went through multiple test but its just like my issue
( Quality problems on walls (Z-Banding?) ) -
My 2 newer printers don’t have the issues at all so with all this testing and reading it seems to me that the belts MUST be worn out as my 2 older printers both have 5.8k ± 100 hours on each printer and the new printers have half 2k - 3k hours.
Also, the 2 older printers had the same issue appear 4-5 weeks apart from each other. -
I will be replacing belts and HOPE that resolved the problem.
