Unable to make External stepper driver work
-
Hi i am using an duet 3 6hc with and 1xd expansion board and i am trying to connect an external stepper driver i am currently not getting any movement when i try to extrude or retract on the dashboard. im pretty sure i have my wiring right but i dont know if my config is 100 percent from what i have looked into i seems to be okay. I send the command to check if xd board is conected with m115 b122, thanks. This is extruder i am trying to connect https://docs.dyzedesign.com/pulsar.html#reprap-firmware

@cj19944 this is the mircostepper drive ,the green light is on constantly which says it is not enabled

Here is the drive it is an r60 model.

@cj19944 the enable polarity varies between drivers. Try swapping the ENA+ and ENA- wires over; or alternatively, change R1 to R0 in the M569 command for that driver.
PS - you could drive the motor in that device directly from the 6HC. The documentation says it needs 2.7A RMS and the 6HC can do up to 4.5A RMS.

@cj19944 See @dc42's answer for enabling the driver.
M569 P122.0 S1 R1 T3:3:3:5:0
This is incorrect; you have five variables for the T parameter, when it only takes four. See https://docs.duet3d.com/en/User_manual/Reference/Gcodes#m569-set-motor-driver-direction-enable-polarity-mode-and-step-pulse-timing
There is no information in the driver user manual about pulse speeds, and your current ones look very fast. Once it is enabled, try something a bit slower and more standard for external drivers, eg:
M569 P122.0 S1 R1 T5:5:10:10
Then reduce the timings to find the limit, if needed.Ian

Really appreciate your help I will try these changes and see what happens.
-
Hi this issue is solved now by changing r1 to r0 and adjusting the timing, thanks again for your help.

@droftarts the Pulsar manual gives this suggestion for the driver timings:
M569 PXXX SXXX R1 T3:3:5:0
