Can't set Z probe offset

$
0
0
I have a Delta printer.
I've just upgraded it with Hiwin and new carbon rods.
I can't set the proper nozzle height and so the printer goes too close to the bed and don't extrude.


  • I have a nozzle based probe
  • i have optic endstop
  • This system always worked with this setup
  • I upgraded marlin fw and back then i have this problem
  • I tried + or - 0.4mm and even 1mm buth nothing changes


Here are some pics:
