Topwisdom does not cut or engrave

Hello all,
I have a laser machine with topwisdom controller.
I can move my laser via lightburn, have it fired, etc.
I can also send a file to the machine and have it lasered.
I think everything works, only the laser does not want to cut or engrave.
With manual firing, he does make a burn.
Do you know what could be causing this?
