Ok, first of all I’m a total newb to cnc so I’m sorry if this is a simple answer that I’m missing.
I just finished building my X-carve and everything seemed to work great, aligned the v wheels and tightened the belts (to the best of my knowledge anyway). Then set out on my first project, clamps.
It was going great until about 90% of the way through when it seems like it shifted everything up the y axis by 2cm. I aborted the program and when the machine returned to home the Z and X axis both were right but the Y way still set back 2cm from where it should have been. I included pictures of when the machine first drifted, the other picture is when the cut was aborted and machine returned to home. Also Ignore the shallow cuts in the first picture, meant to change the design before I cut it but didn’t realize until it was to late.
Until it drifted everything seemed to be going fine, I didn’t notice any struggle from the machine and the only motor that was even warm to the touch was the Z axis so I don’t think it was overheating (Y motors still felt cool).
TLDR; Y axis moved 2cm halfway through a project and I don’t know why.
