@alankilian I sure appreciate your help on this. Thanks

@coseng said in 1XD Closed Loop Servo Setup:

Thanks - I'll keep this in mind for future projects.

@alankilian Thanks for the update. Is there any other straightforward way to test the LeadShine encoder on the Duet2 or would you need a Duet3?

@stuartofmt Thanks for your recommendations. I actually found another camera that worked instead.

@stuartofmt I am receiving this error message while testing to see if the USB camera will work with DuetLapse3. Does this response mean the camera is not compatible or might I be overlooking something else?

That's really kind @alankilian. I'll let you know if I decide to try this again.

@cosmowave Thanks. Much simpler than I expected. This works in the print file.

@alankilian Thanks for double checking. Everything is connected properly.

With everything connected or disconnected I am still receiving the blinking green light with no errors. I'm going to try a simpler motor/driver for now and I may come back to the Leadshine system later.

@shauncro Thanks for the details. I tested your config.g and servo driver settings with my Leadshine setup and am not getting any movement. If I come back to this setup and have success I'll let you know.

@ratrig0331 Great use of an old cpap machine

Can someone give me a suggestion on a code statement that I can use to run a gcode loop X number of times?

@ratrig0331 Just curious what you're using a cpap blower for... to control your duet machine or to help with sleep apnea?

@alankilian Thanks for looking into this. The motor is a Leadshine
ELDM4010V24HL-B5

Here is the response from Leadshine: "Motor speed out of control " this Alarm is from 1XD controller.
Please check controller electronic/PPR setting ,make it correspond to servo driver and machine transmission devices.

I downloaded the Leadshine software to configure it but am waiting for an RS232 cable to test it out.

I'm using the ELD2 Servo controller.

@jay_s_uk Here is the full data sheet for the Leadshine ELD2 Driver:

@shauncro Leadshine contacted me and recommended the Differential Connection option wired as follows:

I tried this but it tripped the "Motor speed out of control" alarm right away even before sending a G1 command to turn the servo.

@jay_s_uk I added T5:5:10:10 to the config but I am still receiving the alarm.

@dc42 The closed loop servo is on drive 122.0 on the 1XD Exp Board. I'm able to turn the motor briefly until I receive the "Motor speed out of control" Alarm from the ELD2 servo driver.

This is how I have it wired:

@marcossf Thanks for the detailed recommendation. I'll check it out.

@shauncro Thanks for keeping me in the loop. I haven't tried the tuning software yet. Maybe once I get the closed loop servo turning.

@shauncro Thanks for adding a valid link to the manual. After reading through more of the manual I'm seeing how much more complex driving a servo is than a stepper.

If anyone can recommend a servo driver that you are having success driving with the 1XD please let me know as I am open to switching if it would simplify things.

@dc42 It's a closed loop servo with an incremental type 2500-line quadrature encoder, 10,000 PPR.

I double checked the wiring (single ended mode) and everything looks OK but I'm still having trouble turning the servo.

@fcwilt Ok - I'm using M950 S1 C"122.out0" but am still not getting motion. I'll double check my wiring again.
