Help! "Error: G30: Z probe 0 not found" upgrading RRF2 -> RRF3

  • Hi!
    Recently I've upgraded my Duet board from RRF2 to RRF3. After this upgrade I'm facing an issue with G30 S-1. Sending it gives me error:

    Error: G30: Z probe 0 not found

    I'm using a switch, which is connected to e0 stop. This setup worked fine on RRF2. Right now I have no idea what to do.
    Please help! Thanks!

    Sorry if I posted in a wrong place.

  • @BananaMuffin said in Help! "Error: G30: Z probe 0 not found" upgrading RRF2 -> RRF3:

    Error: Invalid Z probe type 4

    Z probe types 4, 6 and 7 are no longer supported. Instead, use type 5 (filtered digital) or 8 (unfiltered digital) and use the C parameter to specify the input. Note, if your Z probe is connected to the Z endstop input, in RRF 3.0 on Duet 2 boards only (not in RRF 3.01 and later, and not in RRF 3.0 on Duet 3), that input is by default pre-assigned to be used by the Z endstop, so you must free it up first.

  • Wow, that was a fast reply.
