      ive read the document, though i dont see alot of information about dual Z endstops
      https://duet3d.dozuki.com/Wiki/Bed_levelling_using_multiple_independent_Z_motors
      also theres also this so im still a bit confused about the right / wrong way to go about this
      https://duet3d.dozuki.com/Guide/Independent+Z+motors+and+endstop+switches/18

      2 Z screws connected to Y and E1 .. I used Y because my Y is serial Dual steppers also... so i put them on the Z plug

      right now my config.g looks like
      ; Drives
      M569 P0 S0 ; physical drive 0 goes forwards
      M569 P2 S1 ; physical drive 2 goes forwards
      M569 P1 S1 ; physical drive 1 goes forwards
      M569 P3 S0 ; physical drive 3 goes forwards
      M569 P4 S0 ; physical drive 4 goes forwards
      M584 X0 Y2 Z1:4 E3 ; set drive mapping
      M350 X16 Y16 Z16 E16 I1 ; configure microstepping with interpolation
      M92 X80.00 Y80.00 Z800.00 E420.00 ; set steps per mm
      M566 X900.00 Y900.00 Z12.00 E120.00 ; set maximum instantaneous speed changes (mm/min)
      M203 X6000.00 Y6000.00 Z180.00 E1200.00 ; set maximum speeds (mm/min)
      M201 X500.00 Y500.00 Z20.00 E250.00 ; set accelerations (mm/s^2)
      M906 X800 Y800 Z800 E800 I80 ; set motor currents (mA) and motor idle factor in per cent
      M84 S30 ; Set idle timeout

      ; Axis Limits
      M208 X0 Y0 Z0 S1 ; set axis minima
      M208 X350 Y350 Z850 S0 ; set axis maxima

      ; Endstops
      M574 X1 Y1 Z1 S0 ; set active low and disabled endstops

        for dual endstop you should upgrade to rrf3

        see

          Your config.g file indicates that you are using RepRapFirmware 2, so the second link in your post is applicable. However, if you are ready to upgrade to RepRapFirmware 3 then it supports multiple axis endstop switches much more directly.

            @Veti RR3 runs on Duet 2 ? I thought it required a raspberrypi 3 ? or is that just for a Duet 3 ? and how does one convert working configs ??

              @dc42 so... Thanks foir the input, use the second link if i stay on RR2, use the first if i decide to go to RR3.... what scares me is the config changes required to get to 3 from 2 when i almost have 2 completely configured properly. 🙂 and RR config doesnt seem to work for RR3.

                yes

                no, not even on the duet 3.

                      works for me. did you forget to add the io mapping?

                        @Veti must have been cashed in the browser.... ok went through it again i see 3 issues..... doesnt appear to let me map E1 to Z2 ... manual edit i guess, hrmm hows the second Z stop get configured LOL 🙂 kill me now... ok ok putting on the patience hat.... and second BLtouch is blanked out 🙂 ... i generated what i could for V3 lemme start manually editing to match what i had for v2 ......

                          you need to assign PWM Control Channel (BLTouch only) in io mapping

                                    And below where it states, makes completely no sense to my brain, can someone explain ?
                                    You must use the M671 command to define the X and Y coordinates of the leadscrews
                                    where my left and right Z screws are at 225 to the bed which is centered of the 450x450 bed

                                    M671 X-20:220 Y0:0 S0.5 ; leadscrews at left (connected to Z) and right (connected to E1) of X axis
                                    M208 X-5:205 Y0:200 ; X carriage moves from -5 to 205, Y bed goes from 0 to 200

                                          what are you trying to do now? dual z endstop or independent leveling?
                                          thats only needed for the second one.
