I’m using ground control, and it seems to me that the Z axis moves much faster when touching zero for calibration. Basically, it seems like the motor is free running.
But when you send a “G0” code to bring the bit up, it seems like it’s much slower.
Anybody know why that might be?
how do I get my Z retracts to go “up” as fast as touch zero goes down?
Frankly, it even sounds different. when I’m touching zero, it’s clearly running full out.
when I retract to safe height, it’s almost like it’s trying to hit a specific rate and correcting along the way; much more “buzz/whine” sound for retract than for touch zero, which just a running motor sound.
Also, somewhere in the commands or the status that is displayed in the lower right, it says that the Z-feed rate is 1 or 2mm/min. I know it’s going way faster than that.
