Looking for a source for firmware for my Sainsmart 3018 Prover, seems GRBL (candle) not communicating with the machine, customer service attempted to help but they suggested new firmware for machine which they do have available yet.
Yeah, those Genmitsus with their custom GRBL controllers are a problem. If the sender (Candle) is not talking to the GRBL based controller it could be any number of things. Was it working before and stopped?
Measure twice, cut once and CROSS OUT THE WRONG MARKS.
