      Hi there,
      We cant get working DM556N-L stepper drive from STEPPERONLINE.

      Wiring:
      LCD_DB5 Step 10 -------> PUL +
      LCD_DB6 Dir 10 ---------> DIR +
      LCD_DB7 Enable 10-----> ENA -
      ------------------ +3.3V -----------> ENA+
      -------------------GND-------------> PUL-/DIR-

      Voltage:
      Voltage between ENA+ and ENA- : 0V starting duet, then 2.7V on first command
      Voltage between DIR+ and DIR- : 0V or 2.7V
      (not 3.3V, what do you think about that?)

      Firmware:
      We tested parameters below:
      M569 P10 S1 T3
      M569 P10 S1 T3:3:5:0
      M569 P10 S1 T5:5:5:0
      M569 P10 S1 T5
      M569 P10 S1 T10

      Problem:
      We did the same test with drive 10, same result, motor get warm but doesn't move, no noise, nothing....
      We are using duex5 so whe can't use Duet Expansion Breakout Board .....

      We thing that this driver needs more than 2.7V or 2mA..... what do you guys thing ?

      Best regards, Simon from Trideo

        Three likely reasons why it doesn't work:

        1. You always need to extend the step pulse timing when using external drivers with opto isolated inputs, using the M569 T parameter. Check the driver manual for how much time they need.
        2. For some external drivers, voltage between the EN pins disables the driver instead of enabling it, and you need to allow for this (M569 R parameter). Check the driver manual.
        3. Your drivers probably need more than 2.7V drive. You can use a 74HCT365 or 74HCT367 chip to level shift all 6 signals to 5V.

          Hi there,
          Thanks @dc42 for answering.
          We solved it! Using other stepper, same model, this one was not working well .... or we burned it making test.

          • Finely 2.V works well!
          • M569 P10 S1 T3:3:5:0 works
          • ENA +/- disconnected (Or use R parameter in M569)

          Thanks!

          Simon
