Hi all,
Apologies for diving straight in with the questions.
I've just picked up a couple of Boxford CNC machines however both have faulty GEG Gemini spindle drive boards. One has been totally chopped out (as in hacksawed from the connectors) but judging by the scorch marks inside the casing it suffered the same fate as the other.
The one from the 260VMC looks like it had the typical C2 failure and the resulting fire took out some of the components further up the board.
The questions really would be, does anyone have one of these boards that would be able to help me out in identifying the burnt components so I can re-order and replace to fix the board ? Either a few decent hi-res photos of the burnt area or if you'd be able to provide me the details, either would be great. If someone could measure the values of the tuning pots that would be amazing.
Failing that, does anyone know if there's any of these boards available or if they can still be bought (unlikely I know) ?
I could do with another anyway as the board got cut out of the 125TCL.
Thanks in advance.
