      Hello everybody hope everyone is donig ok, so recently i've bought a duet 2 wifi and i'm really happy with it but i'm a newbie and there still alot of things to learn. So i'm having this really weird problem, i'm building a ram extruder to extruder clay it uses

      nema 23 stepper (4.2A), R60 microstep driver, 30:1 reducer and for power 'm using a 48V 5A power supply for the driver and 12v 16A ps for the board (duet 2 wifi)

      i'm setting the driver for 6400 steps/mm and 4.3 peak current (stepper uses 4.2A)

      I have two problems : first one is i cant get the stepper to turn any faster i tried all the feedrate from 1 to 60 mm/s no luck always turn in the same speed

      and my second problem is i can't set the driver for lower steps (no lower than 6400) or the stepper will make noise and won't move

      driver wiring
      ENA - goes to E2_EN on the header
      ENA + goes to 3.3v on the header
      DIR - goes to ground
      DIR + goes to E2_DIR on the header
      PUL - goes to ground
      PUL + goes to E2_STEP on the header

      here's a copy of config.g file you'll notice that i've mapped E2 in place of the E1 extruder tweaked other parameters

        How did you determine these timing values?

        I notice there is a space between the T and the numbers, that might not work.

        Please provide the results of sending M122 and M98 P"config.g" in the gcode console.

            @omar221 the probem is from the steps/mm when i set it to 500 instead of 128105,58 it works (with 128105,58 steps/mm when i extrude 10 mm i get 10 mm, i think the number is this big because i'm using a 30 to 1 reducer and 1mm pitch screw))

              @omar221, that steps/mm value is much too high to be usable. Can you set the driver to a much lower steps/rev value?

                @dc42 i've determined the steps/mm value by multiplying the old steps/mm by 10 and divided it by the amount it extruder and when i tested it when i extrude 10mm i get 10 mm
                if i set it to lower i won't get the same result 😥 ,
                with x256 Microstepping set in the firmware the lower i can get the driver is 800 pulse/rev and i still get the same speed for 60mm/s and 1mm/s

                  @omar221 changing microstepping in RRF won't work, because you are using an external driver. But your external driver may have several different steps/rev settings.

                    @dc42 yes it has i tried all of them from 200 to 2560 pulse/rev with no luck

                        @dc42 I think i found the solution i've set the step/mm to 80 the stepper work but there's a small problem when i extrude 10 mm i get less than that, so i need to extrude 400 mm to get 10 mm
                        is there any parameters to change like an extruder factor or a macro or something like that because i can't change the step/mm it will be too high because i'm using a wormgear reducer

                        thank you for your help

                          Yes there is an extrusion factor you can set.

                          https://duet3d.dozuki.com/Wiki/Gcode#Section_M221_Set_extrude_factor_override_percentage

                          But is there not some setting on your external driver to change?

                            @phaedrux I can change the current and the pulse/rev
                            but i think the problem is that the step/mm is too high because i'm using a wormgear
                            like i said i can get the step/mm right it will be 280000 step/mm but i won't be able to change the speed

                              @phaedrux Finally found the solution if somebody have the problem
                              The surface of the 5 mm nozle is 2.5 x 2.5 x 3.14 ( Pi ) = 19 mm2 ( roughly )
                              Surface of the piston is 35 x 35 x 3.14 = 3846 mm2 ( roughly )
                              So one mm movement of the piston will give 3846 / 19 = 200 mm length output ( roughly again )
                              the the stepper dosen't have to move that far
