Very strange, with last Openbuilds version, at the beginning of a job, i hear a brrrrrrr noise and i am unable to see where it come from. I will investigate......
Extremely unlikely to be software but if you have trouble finding the source - take a quick video so we can hear the noise and we'd be happy to let you know what it sounds like Without a description/sample some guesses: BlackBox case fan dirty/off balance, forgot to remove Relay jumper if you aren't using it and sending S<max values at the start of the job, Grbl settings ($1, etc)
Problem solved, just a story with a loose screw...... With you hex file (grbl with door and z parking motion) all is working fine on computer, but on Interface no poping message with stop/resume, in fact, we don't really know what to do. But your hex file is amazing, thanks !
