Hi, I’ve had the cnc up for about a week - got the kits here. It seemed to work fine, but something has gone south though.
My zaxis seems to sometimes work, othertimes not. I took the stepper off and I’m just running it using manual mode in repetier. For a few minutes it will appear to work, then it starts making grinding noises, runs opposite direction, then will just stop accepting commands. I can turn it off for a while and it seems to “cool down” then I can get a few more commands in. It seems to not like the 1mm steps. (grinding sound) The 10mm steps run smoother - but sometimes in the wrong direction.
I’ve been through the basic software setup on this web site. I’ve even made some carves, but now I’m stuck on this z-axis issue.
My question is how to debug this? Is it the electronics, the software, the stepper?
X/Y seem ok.
