    Hi,

    I cant figure this out; I have the limit switches on all axes, and the hard limits enabled. I have tried adjusting the pull-off distance up to 10mm which is way more than I have measured, but jogging back still always triggers the limit again. Please see video:

    Any tips would be appreciated. Thanks.

    Just remembered to add that I am using an openbuilds blackbox and openbuilds control.

    What switches are you using? I only see the software in the video, can't see your switch setup?

    Thanks, Peter. They are these simple&cheap microswitches.

    Thanks Peter, that sounds like solid advice. However, as I am in Europe, the shipping would cost couple of times the price of the parts. :( Ooznest doesnt seem to carry them, are there any sources for these in EU?

    The Store at Submit a ticket will have a list of resellers (and some insight of who stocks the switches) the world over

    If you really can't find them, add the caps and resistors as shown in gnea/grbl:
