I''m new to CNC. I have a Sainsmart 3018 Pro ver and Im running Carbide Create and Candle. I got setup and ran the 3 test files that came with the Pro ver just fine. I drew a box in Carbide Create, saved it, selected GRBL as the post processor. I set up the machine and hit send. The first 4 lines of code ran and it stopped on the fifth line which is M0; T102. The status of the Candle goes to "Hold" and is in a yellow box. And there it stops.

I'm stumped. Can anyone shed some light on this. Thanks.
