Two stepper motors in parallel

@maddy said in Two stepper motors in parallel:

@dc42 I want to use 2 Nema 23 high torque motors for the y-axis with Duet 3MB 6HC and 32v power supply. Will the series connection of such motors work with the default drivers of Duet 3? If not, how can I fix 2 motors for y-axis? Do I need any additional board for another motor of y-axis?

If you connect them in series, then at high speeds that will limit the available torque and increase noise. Better to connect them to separate driver outputs.

nect them to separate driver outputs.

If I understood properly, I don't need any expansion board for additional drivers. is that right?. My Duet 3 6HC can support 2 motors for y-axis, 1 motor for each x-axis and z-axis, and 1 for the extruder motor. e.g. M584 X0 Y1:2 Z3 E4.
Please correct me if that is not right. thank you for your prompt response.

That's correct
