Anyone know why my z axis would change its work zero in the middle of a job? I can only think of 2 potential reasons off hand, and they are both mechanical:
the router bit got pushed up further into the collet during the job, or
the screws on my motor mount moved the pulley causing the tension in the pulley to weaken and slip. (I’m trying to correct this by redoing my z-axis plate. I have a quick fix to check it out tomorrow to see if it helps (the temporary plate is HDPE) but I’ll cut another aluminum one in the near future, if that corrects the problem.
I’ve never really had too many problems with the z axis up until now, but my previous cuts were mostly 2.5 D, and I didn’t pay as close attention to the z axis depth. If it happened before, it was such a small change that I didn’t notice it.
If it’s program, electrical or controller related, it’s going to be much more difficult to diagnose. I don’t think it is though. Have any of you ever had an issue like that?
Otherwise, my machine has been working better/smoother than it ever has. I was relieved to discover that (other than the z axis issue) the accuracy and repeatability of the machine is pretty spot on. I’ve been trying to cut some of the same 3D reliefs that I made on my 3020 machine on my larger machine in greater scale and dimensions. That’s where I discovered the issue.
