@dc42 It works now! Thank you. I completely overlooked that part

@dc42 I just tried it and it does send the Gcode

@dc42 Could this be a software bug on the arduino side?

Hi!

I have wired and programmed the CNC Pendant according to the Arduino Pro Micro to Duet wiring section https://docs.duet3d.com/User_manual/Connecting_hardware/IO_CNC_Pendant.

I however can't seem to get it to work.

What Gcode do I need to write in my Config.g?

I added M575 P1 S1 B57600 and I can see that the arduino pro micro light gets turned on when I rotate the encoder. (a Green LED is turned on, a red LED is turned on and a dim red LED gets turned on when rotating the encoder)

My axis have been defined using:

; Smart Drivers
M569 P4 S1 D2 ; driver 0.0 goes forwards (X axis)
M569 P5 S1 D2 ; driver 0.1 goes forwards (Y axis)
M569 P3 S1 D2 ; driver 0.2 goes forwards (Z axis)

; Axes
M584 X4 Y5 Z3 ; set axis mapping
M350 X16 Y16 Z16 I1 ; configure microstepping with interpolation
M906 X4200 Y4200 Z4200 ; set axis driver currents
M92 X800 Y800 Z800 ; configure steps per mm
M208 X-3500:3500 Y-3500:3500 Z-2500:2500 ; set minimum and maximum axis limits
M566 X100 Y100 Z50 ; set maximum instantaneous speed changes (mm/min)
M203 X600 Y600 Z600 ; set maximum speeds (mm/min)
M201 X2000 Y2000 Z2000 ; set accelerations (mm/s^2)

The stop button does however send the Halt status to the duet 3

I am using a Duet 3 Mainboard 6HC V1.01A and plugged the connector into IO_0
