Haha, yeah, must remember to remove the probe.
Fortunately, my DIY spindle motor has pillars holding the motor and so is directly connected to the tool so I haven't got to worry about removing the croc clip.

The autoleveller software if I remember correctly allows you to set the probing speed which default is 100mm/m I think so it's very slow and the machine reacts quick enough that it doesn't damage the board. Similarly, I set the retract height to 1mm so that it retracts quickly and moves to the next point quicker. Could even set it to much less than that really for quick probing.
