Nema42 ClosedLoop on 1HCL + Duet encoder in combi with 1XD
-
Hi Guys,
I have a Large scale printer where i use 4x Nema42 motors on the Z axis. These beast have their own drivers controlled with step and direction via 4x 1XD.
Now i want to run these in Closed Loop mode via the Duet system. My question is; can i run the duet encoder on the 1HCL and run the step and direction on the 1XD or does the motor need to be connected to the 1HCL as well?.
PS: if someone knows a closed loop motor + driver combo capable of 25+ Nm of torque (Nema34 or 42) let me know!PS2: does anyone know if i can remove the back plate of the motor safely or is this holding something back?

The motor needs to be connected to the 1HCL as well. It would be too slow to read the encoder on the 1HCL, then send the movement required via CAN to the 1XD, and then to the servo drive. Having the encoder and stepper driver connected to the same MCU is the only way for tight closed loop control.
