I can fire the laser by using the Test button located directly on the power supply without issue.

I followed your suggestion and jumped the L to Gnd (image attached) on the power connector cable, but unfortunately, this did not work for me. This replicates what the board does and should fire your laser. You can see the mini pinout diagram to identify these. If the L wire is not seated/connected correctly, would the Laser Indicator still light up?įast forwarding a little bit, power down first, disconnect the large power connector from the mini and within the power connector touch L to Gnd. I can see the laser indicator light (on panel) does brightly light up.ģ) L wire in the power connector: I have not checked this as of yet (I did attempt to push the cables in slightly, but that did not do anything).

First, thank you for taking the time to respond.ġ) Potentiometer/ digital panel: I set this to 99.9 just to see if it makes a difference, and then used your command below.Ģ) Using your command of “G1 X10 S0.6 F600” does move the laser +10, but the actual laser does not fire. L wire in the power connector has gotten loose/ not making contact.Īlso the stock usb cable is know to cause communications issues, not saying that’s responsible for this, but keep in the back of your head for later. Potentiometer/ digital panel on the laser power is set too low. Here are the top reasons that the laser does not fire:

I’m about to sleep so I haven’t watched your video. The Laser Indicator light seems dim to me (compared to in the past).ĭoes anyone have any suggestions on what I can check to solve this issue? The laser will turn on (test fire) if I press Test directly on the power supply. I do not think it’s a setting with LightBurn, but more possibly an issue with the Cohesion3D communicating to fire the laser. No issues during the install, but I can not seem to get the laser to fire while running LightBurn. Hi, I just installed the Cohesion3D mini on my newish K40 laser.
