Having some issues today. For some reason my machine doesnt want move back to zero after G00. What is happening is it will make the cut at feedrate then G00 pull Z up to .4" then it wont move back to start of cut. It happened 5 or 6 times today. Just this one cut. Everything else today has seemed to work just fine. But after this one particular cut it would go for awhile then not go. Then I reset, work for awhile trying to finish cut then stop again. Havent run a ton of parts on this machine but never ran into this problem. Really frustrating to have to reset zero continually and having hand on Estop the whole time.
My guess is maybe adjust kernel rate. The machine is well oiled. Checked that to make sure my oiling system is still working. The PC has been tuned as much as I think I can optimize it for Mach3. Any suggetions besides rewriting gcode.
