Setting the machine origin

[Joerg_Wagner]

Hello to everybody, I just signed up and would have the following question:

I’m using a small CNC 3018 Pro with hard limit switches. After the homing cycle Lightburn displays a machine position of X: -292,00, Y: -160,00. The negative values prevent me from using the “Move to position” command, since it only allows positive values. Any idea where I can change the machine position to 0/0 after the homing cycle?

Thx for your support,
Joerg
