@elmoret Thank you. I bought it online years ago. Not sure I can remember. Why do ask?

@Phaedrux 4th axis cnc that I will send gcode to from the gorgeous duet browser gui.

Duet browser connects great, but when yoy try and jog the machine manually . whar used to work the night before perfectly... Stopped working the next day?

Can you see Or catch anything wrong with this video?

If there are diodes in the board after the stepper driver on the maestro 2, wouldn't they limit any current coming back up to the board?

@dc42 Thank you so much for responding quickly!

Here is a video showing everything going on.

It has the right green lights. 23.9 v to the board. And the short happened After a wire came loose.

I saw it burn and give off a small amount of smoke to% my drivers. But signal chain wise the short must have come after the board? Is that true? I waz plugged from the duet the e0 to 4th axis module.
Thank you again

@bearer thank you! My board is thr Ethernet 2 maestro.
I just replaced power supply. I noticed this when I did switch to 24v from 12v. Thats another possibility to look at?

All lights and correct and voltages have been doublw checked

I'm so bummed out right now if this is true.

Worked fine after wiring. Over night nothing changed or even moved in the slightest position wise of the board on the "anti static bag"

It stopped wotking.. Please help!?
Ive been banging my head against the wall
Thank you so much in advance!

I had another stepper driver burn from a 4th axis module..
Is my board fried?!! All lights work though.??!!
