i built a lasaer engraver with a grbl board and it seemed to be working. but now i run the program and the laser stays on as soon as i turn on my laser engraver. all the connections are good nothing is connected wrong. any thoughts? do i need to download the latest software for the grbl board?
Hi and welcome @jmp1333 ,
Do you have the code you used in a Gist or in a repository?
