Since you changed the motor and the encoder, we can rule them out. Did you check the ribbon cables for wear? Is it failing on the same 3 components? Is it failing around the same area on the board? Does it fail when you cycle a tool, multiple times?

There are a couple of things that you can do. First thing to do is take a flashlight and shine it in the card edge connector of slot 2 and see if a passive component or any other part worked its way into that slot. This will cause multiple leads in
