      Hi,

      Based on this:
      https://forum.duet3d.com/topic/6993/requests-for-help-gcode-cam-follower-tangential-knife-control/5

      I create my own "script" to generate the Gcode with a extruder axis and amount of material, like this:

      G1 X95.00 Y20.00 Z0.00 U0.00 E25.15
      G1 X96.00 Y20.00 Z0.00 U0.00 E25.15
      G1 X97.00 Y20.00 Z0.00 U0.00 E25.15
      G1 X98.00 Y20.00 Z0.00 U0.00 E25.15
      G1 X99.00 Y20.00 Z0.00 U0.00 E25.15
      G1 X100.00 Y20.00 Z0.00 U90.00 E25.15
      G1 X100.00 Y21.00 Z0.00 U90.00 E25.15
      G1 X100.00 Y22.00 Z0.00 U90.00 E25.15
      G1 X100.00 Y23.00 Z0.00 U90.00 E25.15
      G1 X100.00 Y24.00 Z0.00 U90.00 E25.15

      It's possible to set U or A (or other) like a extruder axis ? How I can ajust this in the firmware?

      EDIT:

      this ? https://duet3d.dozuki.com/Wiki/Gcode#Section_M584_Set_drive_mapping

      The machine understands automatically the U commands and E commands ?

      My U must be C ?

      I connect the motor to the E2 extruder ? What is the wiring diagram ?

      this ?
      M584 X0 Y1 Z2 E3 C4 (for E1 Driver) ?

      thanks.

        That's correct, create a new axis (e.g. U or C, it doesn't matter which as long as you are consistent) for the extruder angle control using the M584 command. If you need to home it, connect the homing switch to the E0 endstop input.
