This problem just started for me. When my Z axis hits the limit switch during the Easel homing sequence, it reverses direction, plunging into the table if not stopped. This used to work fine, only difference is I started learning how to use UGS (which I like!). When I try a home sequence in UGS, the limit switch does not seem to stop the Z axis when it hits it. The switch is still working when tested on a multi meter.
I can still use the XCarve, but not being able to home it kind of bugs me. Any thoughts?
Check the wiring for your Z axis starting at the gShield/X-controller all the way to the Z stepper motor… Look for loose wires or wire strands shorting to a neighboring terminal.
Your $24 and $25 settings are high. Did you change them, or was that the default?
Yes, that fixed it right up. I saw that setting yesterday and thought it was the cause but I did not know how to make changes to these settings. I learned how to do that now… thanks very much! Not sure how they were changed unless I did something in UGrbl.
I do note that my Y axis is very loud now, but only during the Home procedure. If I jog it is quite smooth… I almost wonder if the steppers are fighting against each other.
