Hi - in Fusion 360, if you don’t position your bit above your clearance height when you start, the processor isn’t smart enough to move you up and the bit will crash. gSender has support for this in the safety settings, but ONLY for the “go to” buttons, not for job start. Safe Retracts to Clearance Height works fine in general, but the first move can crash the bit. The way to protect ourselves from this is to have Fusion always send a Z move to Clearance before any other operations - but I confess, I don’t know how to do this. Anyone have any tips? I suspect I may have to edit the grbl postprocessor, but I’m surprised nobody else has done this!
Yes, I can manually clear the bit each time, but that’s a human operation, prone to failure, and for high moves that can almost hit the limit switches, I find the responsiveness of Jog controls on gsender so poor that I can’t easily use my joypad/control to get close every time. Sigh.
