Bridgeport interact 4 help / advice needed.

You really need the schematic diagram. The SMD caps don't generally have markings and you may also struggle to identify the smaller semiconductors. Looks to me as if the board is severely roasted, so a lot of the tracks may be geography now. Speaking as a power electronics engineer, I'd say your chances of success are limited.

But the cause of the blowup may be the big switching devices rather than the drive circuit on the board. To the left of the photo you can see a glimpse of one of these - have you tested them to see if they are OK?

It seems these drives are rather prone to popping. There was a guy over on another forum very recently (not sure now which one) with a similar issue although I don't know how he got on trying to replace the controller. The motor has both a stator (stationary) winding and a rotor winding, requiring a control circuit for each. It may be simpler to swap for something more conventional like an induction motor and a VFD although this sounds mechanically painful.
