[FluidNC Issue#1508] Problem: Motor is not moving

Wiki Search Terms

I’m new to the FluidNC 6X controller and currently trying to get a single NEMA 23 stepper motor running using a DM542T driver. I’ve gone through the wiki documentation and searched through many forum threads, but I haven’t found a case that matches my issue.

Here’s what’s happening:

I’m trying to control the motor through the web interface.

When I issue a movement command on the X-axis, both the STEP and DIRECTION LEDs blink

Despite the blinking LEDs, the motor doesn’t move at all—no sound, no vibration.

I’ve double-checked my wiring and pin configuration, but I might be missing something. Has anyone experienced a similar issue or have suggestions on how to troubleshoot this?

I also check the motor enable and disable. The motor is locked while sending $ME command And can be rotated by hand while sending $MD command.
Also , I can feel motor being heated up.

What happened?

Once the WebUI page loaded , I tried to Jog by pressing the X+(10) button and expected the motor to move but its not moving at all.

It appears everything is OK. Try sending a few commands from the console. You can use the console in the WebUI, FluidTerm or the Web Installer terminal

Send $report/interval=200. This will turn on auto reporting.

Send $J=G91 G21 F1000 X10. This should jog the the X axis 10mm in the positive direction. Then send $J=G91 G21 F1000 X-10 to go the other way

You should see the step LED blink dimly and the motor should move 10mm. If is does not move at least see if the motor is locked.
When you change the direction, the direction LED should change on to off or the other way around.

You should also see the position change on the WebUI and when you send ?

Report what happens. If you see any alarms or warnings, let us know.

What is the setting for the DM542T’s control voltage switch ?

Hello everyone, The issue is solved. My driver was damaged . I replaced the driver and its working fine.
