Running Ubuntu with LinuxCNC v2.7.3. Nothing else running on the Dell.
Sometimes when I "G0 Z0" LinuxCNC goes to Z 0.1 ( metric). It also then goes to clearance at 10.1 when the gcode specifies 10.0 and any gcode specifying a z level is then always out by +0.1.
To solve the problem I have to restart LinuxCNC and go through homing and re-check x, y and z touch off again.
I thought it might have been caused after a re-touch off on z so I tried to reproduce the problem this morning while air cutting but it didn't fault either at a fresh start or after 30 mins of warm up.
Anyone else had this problem or know what could be causing it.
Thanks in advance.
