I have finallly be able to let the software control my airpump for the airassist.
But for some reason, everytime I send a new job to the machine the airassist starts, llaserhead will start for like the three first lines and then stop and the airpump still runs.
Only way to get rid of it is to unplugg the USB and reattach.
This results in homing and I can send the work again and now it will finish. The next job will results in a stop again and the restart is required again.
Pretty annoying since I can do 200 identical jobs in a row.
This never occure if I unbox the airassist.
