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

  • 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.

    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
