Guys, I'm pretty convinced I've found the problem. I believe the encoder/cable for Z is the problem, simply picking up noise. When Z is run by itself there's no or very little offset. I noticed that when I executed the EMC Axis logo the servo caused sudden jumps. So I made a new test program where Y and Z was moving 10 mm back and forth at the same time. I could actually hear the servo jumping. I think it's a TTL encoder and they are really sensitive for noise, and quality cables doesn't really help. I've mounted a new CUI differential encoder and I'll make a new cable. If that works I'll replace them all.
I really hope this will the end of the story. --S ------------------------------------------------------------------------------ Come build with us!
