How can I get Z lift to safe traverse or “clearance” height (as defined in Fusion360) before the move to the first cut position? I either had a bad Z number or a bowed board and the bit dragged a line all the way to the start position, ruining my board (lucky it was just a test piece).
Any way to force a Z move before the travel? I can manually turn on the spindle after the move or I can copy and paste a Z move but I’d like to find a permanent solution.
That is going to be a setting in Fusion since it’s a command that should be in the gcode. You are probably also safe to manually command the z-axis to a safe height after zeroing it. The G0 X-151.... command will move the machine to the starting location and then the G0 Z5 will adjust the z-axis height as needed.
I inserted the Z move into some cuts and it works great. I also found that just moving it manually right before I hit play is faster and easier. It would be good to throw a warning in for beginners somewhere to avoid a ruined stock piece.
I’m pretty surprised that fusion doesn’t do that automatically. Most CAM programs should do that without you needing to do anything
I’ve been looking high and low for some kind of “pre-script” section like you would find in a 3D printing slicer but there’s nothing. I also just discovered that if I group operations by bit and create an NC program, the drop down for post processor doesn’t have the custom maslow one, just a generic GRBL processor. I guess I’m post processing and stitching different cuts together now. Making me want to take a serious look at another program for control and just use F360 for the design part.
