Cheers Hood, I think all the other LYNX drives are in museums,did find a picture of one on another CNC site but guess what the same component was burnt out. Looked on ebay and there are a few components that might be correct, as you said its just getting the right one. Its strange worked most of the day on some mementos for a child's charity with no problem. Then after about 4 hours I heard a buzzing from the motor and it started to rotate. I can live with it till it gets warmer and I don't freeze, I just turn off the machine to change the tooling. Going to go and clean up the workshop this morning so will have another look to see whats written on it, keep you posted. Jim
