After about two weeks of very successfully using my Mini, I’ve hit an unexpected snag. The X/Extruder harness cable guide (the thing that looks like a plastic bicycle chain) “hangs” lower than I remember when I first started using the machine. At low x (extruder to the left) and z (extruder down) positions the cable guide drags over the print bed.
Worse than that, when the extruder returns from the initial head wipe, the guide now snags on the wiper pad and holder unless I lift it manually.
I have examined in detail the first few “links” of the cable guide and found no link snapped out of place. The first link (male cable guide connector you call it on the ohai-kit description of the X carriage assembly workflow) appears to be solidly attached to the upper bearing holder.
As seen in the attached photo, the angle between the above-mentioned “connector” (first link) and next link appears to be significant - yet I can’t find anything broken, bent or out of place in the links.
Unfortunately I did not pay enough attention to the cable guide when I first got the machine (except to remember tidied NOT snag the wiper pad) so I can’t tell what, if anything, looks different.
Any ideas? I’m having to manually hold the cable guide up during the first few passes…
