Hi Ludwig,
?
Thanks again for the link! I did take a look at the document and followed the steps for troubleshooting the SMPS boards using the terminal. Unfortunately, both of my assembled QMX boards only consume power when I press the left encoder button, but they immediately stop drawing any power as soon as I let go.
?
I¡¯ve closely inspected both boards for any signs of physical damage, like burned components, but everything looks clean. I¡¯m concerned that the SMPS boards from Kit #1 were damaged when I accidentally applied 30V, and when I placed them into Kit #2 (which was working fine), they might have sent too much voltage to the processor, potentially killing it. It¡¯s really disheartening, as now I might have two damaged kits¡ªor, at the very least, a lot of spare parts.
?
If you have any other suggestions, I¡¯d really appreciate them!
