Como faz pra o laser parar depois de executar um comando?

If I understand correctly, this happens to me whenever in the “Laser” window I have “Start from” set to a different setting than “Absolut Coord”.
I didn’t understand if by “Corner of the machine” you mean “Home” or “Finish Position”. If this is the second case, try going to “Device Settings”, entering the coordinates you want where the laser head stops in the “X” and “Y” fields and select “Reurn to Finish Position”.
I use this function a lot to move the laser head away from the work and be able to remove material without having to move the head manually or lose coordinates.
