      ; Endstops
      M574 X0 Y0 Z0 S1 ; set active high endstops

      I am not sure, but here you say that it has no endstops. Is this intended?

        I'm not sure if the following are causing the X 0.6, Y 1.7 and Z 431 offset, but they should be changed:

        M666 X0 Y0 ; put your endstop adjustments here, or let auto calibration find them

        This should have your Z endstop offset in there, too, though currently just put in:

        M666 X0 Y0 Z0 ; put your endstop adjustments here, or let auto calibration find them
        

        ; Axis Limits
        M208 X0 Y0 Z0 S1 ; set minimum Z

        You don't want to limit X and Y to 0, as Deltas home in the middle, so X and Y need to be able to go negative! The delta radius you set with M665 will limit X and Y. Use:

        M208 Z0 S1 ; set minimum Z
        

        ; Endstops
        M574 X0 Y0 Z0 S1 ; set active high endstops

        This is saying "no endstops on X, Y and Z". See M574. I'm surprised the axes stop at all when homing! Almost certainly you want:

        ; Endstops
        M574 X2 Y2 Z2 S1                            ; Set active high endstops
        

        M350 X256 Y256 Z256 E64 I0 ; configure microstepping without interpolation

        You almost certainly DON'T need to be running with 256x microstepping. This can limit speed on a Delta. Set it to 16x with interpolation, and change your steps per mm.

        In homedelta.g:

        G1 S2 F6000 ; move down a few mm so that the nozzle can be centred
        G90 S1 X0 Y0 Z430 ; absolute positioning

        That G1 move has no coordinates, so there's no move.
        That last line should just be 'G90' on it's own. G90 doesn't take any parameters.
        I think it's a cut-and-paste error and should be:

        G1 Z-5 F6000 ; move down a few mm so that the nozzle can be centred
        > G90                         ; absolute positioning
        

        Edit: still in relative mode, so need to move Z down -5 from homed position. Or do the G90 first, then move to X0 Y0 Z425.

        Edit: Use G1 H# rather than G1 S#, assuming you're using the latest version of the firmware. G1 S# is deprecated for homing, though still works in RRF2.x. My homedelta.g on a shorter Delta:

        ; homedelta.g
        ; called to home all towers on a delta printer
        ;
        G91                        ; relative positioning
        G1 H1 X184 Y184 Z184 F1800 ; move all towers to the high end stopping at the endstops (first pass)
        G1 H2 X-5 Y-5 Z-5 F1800    ; go down a few mm
        G1 H1 X10 Y10 Z10 F360     ; move all towers up once more (second pass)
        G1 Z-5 F12000              ; move down a few mm so that the nozzle can be centred
        G90                        ; absolute positioning
        G1 X0 Y0 F12000            ; move X+Y to the centre

        Edited: saw extra mistake in homedelta.g

          M201 X1000.00 Y1000.00 Z1000.00 E1600.00 ; set accelerations (mm/s^2)
          M906 X1600 Y1600 Z1600 E1600 ; set motor currents (mA)

          Your accelerations are set quite low (mine are 4000, but it's a smaller, lighter Delta) and your motor currents set high; what motors are you using?

              @droftarts It's nema 17 motors, you can using 1.68A on this motor, no problem πŸ™‚

                @droftarts I changed the value. I have the problem, the z is 5mm to high during the printing.
                I changed the homed heigh from 430 to 435mm but i have g0/g1 error, target position not reachable from current position.
                What is the problem?

                thanks for your help.

                  What M208 commands are you using, if any?

                      If your motors are rated at 1.68A, they will get hot (+80ΒΊC) if you set the current to 1.6A. You should set the current at a maximum of 85% of rated current, so around 1.4A. This way you will still get close to maximum torque, but the motor shouldn't get more than warm. See https://duet3d.dozuki.com/Wiki/Choosing_and_connecting_stepper_motors#Section_Rated_current

                        Hi ! I know you've solved the problem you initially asked about. I'm wondering it you could give my some info on how tricky putting a Duet board on a WASP delta was? I have a WASP 60100 (build 2017) and would love to upgrade it with a Duetboard and maybe a E3D Volcano hotend. But, I'm not really sure what I'm getting myself into πŸ™‚ Would you mind me asking a couple of newbie questions about your process?
