Atomstack a24 - xy coordinates in negative space

I have a a24 and installed it, completed few jobs, but then the xy coordinates kept jumping, now to the point they are -97 for x axis and y of 96 even though its in the front left axis and origin for device settings of front left.

The laser is positioned the front left, and I cant even job it up, it tries but bounces back like it hit a limit. What can cause the coordinates to change like this?

Aside from this coordinate issue and not being able to jog up and use the actual bed space, I do hve a homing issue alarm 9 as well, not sure if issues are related but I double checked the connections for the switches but get this code:

ALARM:9
Homing fail. Could not find limit switch within search distance. Defined as 1.5 * max_travel on search and 5 * pulloff on locate phases.
[MSG:alarmCodeCodeIntHandle:9

Maybe you have a work coordinate offset.
Disable Auto-home at startup.
Connect to laser then on Lightburn console window write $RST=# and press enter.
Click the House in the move window.
Test again and report back.

Why is $31=50?

Thanks, will try that.

Regarding the $31 value, that’s a value I have not changed, I’m not to familiar with each of the lines or values so I have not attempted to modify any of the values.

I will report back later this afternoon on my results.

Okay, I believe that worked.

Regardng $31 - what value should that be?

Im so confused right now. Home button always triggered alarm 9, but tht stopped all sudden, first time ever.

$31 should be 0.
