Duet 3 1XD low voltage issue
-
Hi,
I am connecting a stepper motor driver via the Duet 1XD module to the driver out outputs: +5V, step-, and dir-. When I click on the +50 or -50 shift on the panel, nothing happens.
After measuring the voltages with a multimeter on +5V and dir-, it shows 5V, and after changing the direction of movement, it shows 0V (which is correct).
When measuring the voltage between +5V and step-, it shows 0V, and when I click on the +50 or -50 shift on the panel, the voltage changes briefly to 0.05V (while it should change to 5V). What could be the cause?

@sebastianwac What driver and motor are you using? Please post the make and model number, and links to documentation. Also please post your config.g, and what firmware version you are using.
When I click on the +50 or -50 shift on the panel, nothing happens.
Have you wired enable to your driver? Most likely it is receiving the wrong signal, and the driver is not enabled. Often just disconnecting the enable signal will enable the driver, as most drivers are enabled by default.

The steps pulses are sent very fast, and most likely your multimeter can't react quick enough, so you just see the average voltage. However, the step pulses might be too short for the motor driver too. How have you set up the drive in config.g? Generally you need to set the stepper timings in the M569 command and T parameter that controls the motor.

I am generally converting a CNC milling machine into a 3D printer. I want to replace the old motherboard (RichAuto A1X/B1X) with a Duet 6hc and 1xd modules.
The motor drivers are H2-2206, and the servo motors are 863HSM100H. The documentation includes information about pulse times, and they are set in the firmware as follows:
M569 P41.0 S1 R1 T2.5:2.5:5:5Regarding the connections, +5V is connected to 5V, STEP- to PULSE-, and DIR- to DIR-. The drivers do not have EN inputs.

https://forsuncnc.com/wp-content/uploads/2021/11/DSP-A11-User’s-Manual.pdfThis is the second milling machine I am converting into a 3D printer. The previous one was very similar, and it works correctly. The motor drivers there were H2-758. I also connected only 5V, Step-, and Dir- there. I used Duet 6xd there. When I measure the step signal during movement there, it shows 0.5V, which is more than on 1xd.

Never mind. I got it working. The issue was with the time delays.

@sebastianwac Lol, Chinese documentation vs reality!
I was looking at the 1XD and 6XD outputs, wondering if you had wired it differently, as there is a difference between them; the 1XD can do single and differential signalling, while the 6XD only does single ended. However, glad it was something as simple as the timing, and you got it going.
Any reason you're using a 6HC rather than a 6XD for this conversion?

@droftarts At first, I intended to use the 6XD, but I received a pre-wired and configured 6HC bundled with an extruder, so I thought adding 3x 1XD would be faster and cheaper than switching to the 6XD.
