    • RE: G32 Dual Z axis constant 0.6mm off-level difference

      But if the probe always meets the same bed temperature - the variance is constant right?
      Thermistor is there to correct the non-constant bed temperatures to keep the same offset between 60 and 90C but I'm using only one

    • RE: G32 Dual Z axis constant 0.6mm off-level difference

      @dc42 Hope it is a worthwhile bother. I'm at the wits end with configuring duet for my ender 3 and pinda probe since May.

      The Z offset is inconsistent and two Z axis true leveling is inconsistent as well.

      • I have replaced the springs with PCABS washers.
      • Probe measures at static 60C
      • Z rod distances, bed size, probe to nozzle distances are correct.
      • Z motor order and cabling is correct.

      Please, please help

      Duet software turns out to be very difficult to be made to work despite doing everything like the guides said.

    • RE: G32 Dual Z axis constant 0.6mm off-level difference

      Yes but as I use 60C always - It's safe dependable value. Using temperature offsets would just add another fail point and would not impact anything that is failing currently

    • RE: G32 Dual Z axis constant 0.6mm off-level difference

      @Phaedrux I printed a 2cm washers in PCABS and replaced the springs with them. Magnetic bed holds to the bed.

      At first it worked but I started to have hardware/connection issues with temperature sensor in pinda probe. I never used temp corretion, I thought it is not available.

      I always use 60C temp for homing and printing unless I use PCABS but that's not in the equation/files right now.

    • RE: G32 Dual Z axis constant 0.6mm off-level difference

      I also have a trouble with changing Z offset, one week it's 2mm lower and after few prints it goes 2mm up while I'm consistent with the procedure and it is persistent on restarts.

    • RE: G32 Dual Z axis constant 0.6mm off-level difference

      @Phaedrux said in G32 Dual Z axis constant 0.6mm off-level difference:

      You should set the trigger height in config.g and leave it there. You haven't posted your config so I don't know what your trigger height is set there, but if it's different than 0.540 then you're going to have some problems.

      I started getting fine leveling results precisely because I moved it from config.g so G32 works without it. How do I get better measurements with Z offset in there? (they were scattered and inconsistent. I got the motors in the right order.

      At least now they get more even but still I need to home it few times
