      I want to balance my dual extruder setup(RostockV4/SMCNC) without engaging any heaters.
      Duet GUI only allows extrude/retract when temps are at min 180c.
      Is there something I can fudge in the config to allow me to test the steppers without having the HE come to temp? or to something less than 180c?

      Also, GUI only allows me to switch between the extruder steppers by clicking on the Heater ; when I go to Tool_0/1 and try to Select/Deselect the tool it has no effect. Is that normal?

      My extruder config:

      ;extruder E0
      M563 P0 D0 H1 ; Hotend (T0), drive (E0), heater (H1)
      G10 P0 S0 R0 ; Hotend operating and standby temperatures

      ;extruder E1
      M563 P1 D1 H1 ; Hotend (T1), drive (E1), heater (H1)
      G10 P1 S0 R0 ; Hotend (1) operating and standby temperatures

          DOH!

          I had just set that up for the clay machine!
          AND,
          the M302 works.
          Well now, ain't life grand.

          One weirdness is that to select between the extruders I have to use the Heater section(?)

            I'm not sure about that problem.

            What version of firmware and DWC are you using?

              @nurbie How have you defined the tools? Selecting tools should work if you've assigned extruder drives correctly and set the correct mixing ratio.
