How to I make probe stop sooner

Hello I just got a wham bam kit for my Anycubic Predator, but I would like to know how do I get my probe to stop the fast dive sooner so it dont crash into the bed before leveling it.

Here is my config files

See https://duet3d.dozuki.com/Wiki/Calibrating_a_delta_printer#Section_Running_auto_calibration_for_the_first_time in particular the bit about increasing the dive height.

Also, it's generally a good idea to reduce motor current when homing or probing if at all possible, as it will help to limit damage if anything goes horribly wrong.

@dc42

Thank you That did the job

@deckingman

I did that and I can see that could have been a good thing to do if it went wrong
