Unable to run the servo motor

Allaudri

Hi everyone, I'm trying to run my servo motor in position control mode, which only requires steps and direction signals. I used the code from the RepRap configuration tool for my Duet 3 6XD board. However, when I connect it to my servo driver, the motor doesn't move, even when I use commands from the user interface. I'm not sure what's wrong. Does anyone have any ideas? Also, I've included my config file for anyone interested in checking it for potential issues.

I'd guess that your timing is far too fast for the servo driver. Start with something like:

M569 P0.0 S1 R0 T5:5:10:10

It could also be the enable signal, which causes people no end of problems, usually. Please provide a link to the servo driver datasheet or manual, and we'll come up with some better timing for you, and advise on the enable signal.
