@tekstyleI know this is an old post, but I was searching for the same thing today and found the answer here :

Thank you all for your explanation. It really helps ! I'll give it a try.

Have a wonderful evening !

@theruttmeister Thank you for you answer. I'm pretty green regarding motors and I appreciate your input.

I understand that the driver will limit the current and that I can applied 4.4A per motor using the Duet3.

My understanding is that more voltage will allow me to get more speed. Current will allow me to Hold the torque. Am I correct ?

My understanding is that the duet3 will not be able to energize both phase at 4.4A at the same time, but will provide a 4.4A to the whole motor, so the torque will be about the half of the motor capacity ? Am I correct ?

Thanks again !

Thanks a lot !

Hello,

I'm considering buying a duet 3 to build a heavy duty 3d printer. I already have the motors, but I'm a little confused regarding the current draw. I'm gonna run these motors on 24V and they are rated for 4.24A/phase

The Duet 3 is rated for 4.4A for both winding at the same time. Does it means that in reality my motors being bipolar will draw 8.48A and won't be able to be used with the Duet3 correctly?

Thank you for you help.

That's great !

Do you need to generate the gcode as LA 1.0 or 1.5 to get a result compatible with Pressure advance on RRF ?

Thanks
