A20 Controller laser head keeps drifting from Origin

[marko53]

Hello, I installed the A20 controller and the AutoLaser software on my machine. The install seems to be working fine except that the laser head will not go back to the same origin. When the machine is turned on the laser head goes to what appears to be the origin but then starts drifting down the
Y axis for about an inch and then stops there. This is the case whether the origin is selected for "machine, user,etc" . Do you have any ideas on what is going on here? Thanks

It is normal: after homing the laser head move to the set origin point. Please also check manual 12 and 60th page.
If the 1 inch movement is part of the homing movement, it could be a limit switch signal/setting issue.
