Z axis hits upper limit switch mach 3
« on: January 30, 2023, 02:31:01 PM »
I'm having trouble with the Z axis raising and hitting the upper limit switch when I start to run a file.  As soon as I hit cycle start the Z axis raises and hits the limit switch.  This problem seems to have started after I had to replace z motor driver.  I have two laptops.  The same file runs fine on one but not the other.  I compared all the setting in ports and pins and homing and limits between the two laptops and they are the same.  I checked safe z settings in mach3 and they are the same.  Here's what I'm using:

Runs fine on this one
PC, Windows 11
Mach3 w/license
Vcarve Pro

Z axis hits upper limit switch on this one
PC, Windows 10
Mach3 w/license
Vcarve Pro

Have I missed a setting some where?  Could mach3 be corrupted on the win 10 machine?  Any help would be appreciated.

Fixed it.  Deleted Mach3 and reinstalled it.  Problem went away
