g29 crash bed



  • hi, lately i'm having problems with self-leveling, i run the g32 perfectly with smart effector, after step to the g29 for the mesh, towards the last touches it slams the nozzle over the bed and stops, I checked all the cables with the tester are ok.

    another problem that I'm having, during the press it doesn't respond to babysteps, it doesn't get up and it doesn't go down.

    I attach my configuration

    I think you need to go through this document to setup your smart effector properly.

  • It used to work perfectly, strangely now it's stopped. Now I read again this link that you posted to me.
