looks like it went poooof
It looks very like you'll have to replace that board ... multiple component failures! Hopefully, this will be under warranty. In any case, ain't it nice that at least SOME failures announce themselves plainly? :lmao:
Best wishes!
I was going to say that it sounds like you popped a FET, but after looking at your board, I'd say that was obvious.
Not knowing how long the machine was running, what cutter size, DOC, etc., I don't know if you overheated the board or not. But it kinda looks like it.
The duty cycle on these little machines is probably very low. For prolonged usage I would add airflow over the control board/heat sinks to better handle the extra power dissipation requirements. Maybe even larger heat sinks on the FETs.

The control box has filtered vents but no forced air so I think I would wire up a motor to blow air out of the box and have the makeup air come in through the existing filtered holes.If you add a fan to a control box, it might be a good idea to put some kind of air filter to keep out dust and other crud.

I run 3/4" bits once in a while, but my go to bits for hoggin are 5/8" 3 flute (alum) and 4 flute (steel) in both finish and roughing. A quality 3 flute roughing bit eats aluminum like butter @ .060" per pass with no problem.
Something like this maybe?
