Toolboard extruding wrong direction after restart



  • Duet 3 with toolboard using firmware 3.2-beta4 and a Hemera. When I turn on the printer the Hemera extrudes in when I tell it too but when I make a change to config.g (unrelated to anything with the motors) and say yes to reboot . The extruder now retracts when I tell it to extrude and Vice versa. If I power off the printer and turn it back on it works in the correct direction. There is only 1 M569 command for the extruder in the config.g and NO config-override.g file.

    Is there something wrong with my Toolboard or Duet 3 hardware or is it an issue with the beta firmware? I recently commissioned my printer so I haven't ran the non-beta version to see if it still has the problem (needed the features in the beta).



  • Forgot to mention, it's in standalone mode no rPi

    My guess is that when you do a restart without powering down, the main board restarts too fast for the tool board to keep up. Try adding a G4 S1 command in config.g, somewhere near the start but in any case earlier than the first command that refers to anything on the tool board (in particular, earlier than the M569 command that specifies the direction for the tool board motor).

    That worked so far, tested it multiple times.

    Thank You!
