@mballin Ended up being the emergency stop switch, after removing was able to print with no problem! Thanks for the help!

@wurth51 if you get a short between Vssa and a higher voltage then you should get a message on the DWC console warning you of the short.

@duet3questionmaster

Perhaps you could post some pictures of the device?

@dc42 said in Burnt Y-Axis Motor on brand new board?:

It sounds like an infant mortality failure of the driver chip. Assuming it's a genuine Duet, your board will be replaced under warranty. Please contact your supplier.

Thanks for the prompt response. I imagine this is a rare fault?

I will head over to the original supplier tomorrow and complete the warranty.

I used to use a steel ball on the frame to level my old printer when it was set up at a new location- it was much more sensitive to tilt than a bubble level. If the X axis uses a piece of t-slot you can put a steel ball on it and it will be a very sensitive tilt sensor. Then all you have to do is detect the ball, either optically, magnetically, or using a piezo element.

In a dual motor set-up the X axis won't usually tilt while the machine is printing, so the Prusa technique of running the X axis to the top of the Z axis and a little beyond to force the Z motors/screws to sync works pretty well.
