Laser works in manual mode, won't fire when processing Gcode

Well i downloaded Lightburn and edited everything per above. Still not working. I will check wire continuity as soon as i get chance.

Hey Eric,

I don’t use the laser but of course looking at the cables (and especially at the connectors) is what I would do first. By the way “Laser not firing” is a very frequent topic in this forum but since you found this thread I assume you already searched the forum.

If you don’t get it to run again I would write an E-Mail to support@onefinitycnc.com. Hope you report if you find the cause :slight_smile:

Well here is the update.

Turns out it is the Molex connector that is soldered to the board in the laser control box. Trial and error with the help of the forum and Onefinity direct helped me diagnose and pin point the issue. JTECH was great with help. They sent a new unit out to me (which is sitting in my mailbox as I type this). I should be able to install the new unit this evening and get back up and running.

Thanks to all for the assist!
