Today's shelter-in-place project was to tidy up my electronics & cabling & hook up my wireless feed hold. I'm using this remote control relay. It's wired into the 'door' port on the BlackBox & I'm using the custom compiled version of Grbl with the door interlock feature enabled. Pressing the remote button 'opens the door' & this is what I see in the OB Control console: [external from hardware] ] OpenBuilds CONTROL received a FEEDHOLD notification from Grbl: This could be due to someone pressing the HOLD button (if connected), or DriverMinder on the xPROv4 detected a driver fault At the machine, motion halts & the router stops. Pressing the button again 'closes the door' & the Resume button continues cutting. On my Shapeoko & using Carbide Motion, when the door open function is activated, the router would lift to a safe Z height & then stop. On resume the router would start, lower to cutting position and continue. My question is, is what's happening (in red above) normal for Grbl? I think Carbide Control might be doing something extra & I'd just like to confirm that things are working as they're supposed to on the WorkBee. Thanks!
