Hey guys,

I'm helping a buddy set up his k40. He bought the exact same one as me so I suggested he get a mini grbl right off the bat. We installed the mini grbl exactly like I have on mine and having a problem.

We got it to connect to lightburn no problem. The problem is, when we send a file down to be engraved, it moves into position and starts, but the laser never fires. When we cancel it and send it home the led2 turns a solid red with no blinking. To turn it off I either restart lightburn or select a different com and reselect the right com.

I'm not sure its a board problem but thought I would check here since the constant red light might indicate something. I checked the troubleshooting diagram and there wasnt a bubble option for constant red light on led2.

 

His settings are the same as mine:
