Set laser parameter crosshair to minus in the machine

[berni]

Hello.
How can I set the value for the crosshair laser to minus?
The minus button is somehow missing. For Lightburn I had to change the value. Now I wanted to set the value back to the original value. I hope someone can help me.
Thanks
kind regards Bernhard

According to snapmaker there is a bug in the firmware.
Snapmaker Suppurt suggested the following solution to me until there is a new firmware:
Currently you can connect the machine to luban and enter the following command in the console to change the offset value.

M2000 L18 G H
M500

G represents the X offset value
H represents the Y offset value

kind regards
Bernhard
