      I have a duet wifi 2 that I've been using for a few months now and the prints have been fantastic. Everything had been dialed in tight and right up until about a month ago. I'd like to remap my Z axis to the spare extruder driver. When I set the Z axis to E1 in RRF I can control the axis and everything works, except I my extruder (E0) no longer works. How do I fix this?

        Check that you have this M584 command in config,g:

        M584 X0 Y1 Z4 E3

        and that any M350 and M906 commands are later in config.g then that M584 command.

          I checked the config.g file and it does show M584 X0 Y1 Z4 E3; apply custom drive mapping
          The next line is the M350 and a few lines down is the M906. What else can I check?

              @jthunderloc said in Remapping Z axis - troubleshooting:

              ; Tools
              M563 P0 H1 ; Define tool 0

              Your tool 0 is defined as not using any extruders.

                  Add D0 to that M563 command to have tool 0 use extruder drive 0.
