I had a slight mishap last night. I was putting the interface back on the shelf below my machine and hit the homing button. Normally wouldn’t be an issue, but I had a jig on the machine and the first thing it did was drop the Z axis to 5m and then moved Y/X axis crashing my 1/8 end-mill into the jig and breaking it clean off. Is there a way to change the homing to home Y/X completely prior to changing the Z axis? If it would have done then Y/X, it would have stayed above the jig and not cause a problem. I will need to try the single flute 1/8 now to finish my projects.
Homing does Z+ (up and out the way) first, then XY by default: See gnea/grbl You can of course customize it even more, but that wasn't it.
well. That’s weird then. The Z ends at 20.5mm when done with a job, which clears the jig. The homing dropped the z to 5 then started the move. The jig is 13mm tall, 1/2” aluminum plate that bolts to the spoiler board.
Sure you didn't hit gotozero, it does a Z5 first (as its used for checking your zero, we raise up a bit before doing XY) - and of course Z5 is the safest option for a machine you know nothing about in that instance (G53 Z-5 would have been nicer, but not everyone has a working homing setup)
Not easily, and the accident in question shouldn't happen all that often right? Z25 would cause a Z crash at the top of travel on a machine with smaller Z workspace and thick stock. Moving XY first is detrimental for users who just zeroed Z (scratching XY move) as well, can't keep everyone happy There is some plans (but it has to coincide with CONTROL getting the same) to check if Homing is enabled, and has homed, and then the button can use machine coordinates like the fusion post does - but it has to be kinda automatic (based on detection from Grbl settings) - grbl profile parsing was only added in 1.4x series firmwares, so not there yet
