When I move the tool holder by hand I can move it relatively smoothly (no binding), but I do feel some vibration. I can’t tell if that’s caused by resistance in the steppers or bumps on the conduit. I’ve attached a few pictures of a single long diagonal line (about 3 feet). I don’t see any patterns, which I suppose might suggest that the steppers aren’t to blame. Let me know if you disagree with my assessment here.
I think this leads me to believe that the problem might be caused by less than perfectly smooth conduit. I picked up some emery cloth to try to sand out the minor imperfections, but I’m still not 100% convinced this is the issue for sure (I’m also not sure that this is the best way for me to smooth these out). Has anyone else had this kind of issue? Any other ideas?
Thanks for the help so far!
