Wantai dq542ma Stepper Driver in errornous state when not moving



  • I have setup my printer to use external Wantai dq542ma stepper drivers.
    In general this setup works fine, but the drivers report an errornous state (red light) when they are not executing movements.
    As soon as there is movements commanded, they switch to the normal state (green light) and the move just fine.

    Now while this does work fine like this in regards to printing, the errornous state still indicates there is something wrong with the configuration somewhere.

    Any ideas?

  • nothing I can see. but i would suggest checking out the driver timings.
    typically external drivers need slightly longer step times etc.

    Here's what I use for my external TB6600's. They are part of the M569 gcode and would have to be altered to match your driver. This information should be available in their datasheet.

    T2.5:2.5:5:0

    Are you sure that the red/green light doesn't just indicate whether the drivers are enabled or not? When the movement stops, do the LEDs remain green, or go back to red?



  • From https://openbuildspartstore.com/content/DQ542MA%20English%20Manual.pdf:

    1, the status on light’s indication

    RUN: green, normal work light.

    ERR: red, failure light, the motor with phase short-circuit, overvoltage and undervoltage

    protection.



  • Thanks you all, adding the timings to the M569 commands as @jay_s_uk and @PCR suggested fixed it!
