I’ve been cutting for a year now, and suddenly I’ve got an issue. When I run any program, the laser moves, but the laser does not fire. The green light usually seen at the top of the laser when its firing is also absent. No other conditions have changed, so I’m assuming its a problem with the laser itself. S9 Sculpfun.
Remove the cable that connects the controller to the laser module and inspect it for any damage. If you have a way to check continuity then check that the cable is conducting end to end on all wires.
the cable is in working order. Do I need a new laser module?
If the cable is working, you can do a final module test. Plug the signal cable into the 5V socket close to it on the mainboard. As soon as the laser is turned on, the laser should start fire at 100% (so take care). If it doesn’t, the module is broken. Contact Sculpfun via support@sculpfun3d.com.
If it does work, it’s a firmware or software setting. First, check values $30 to $32. It seems that LightBurn is somehow changing them randomly occasionally.
It’s described (also the plug test) in more detail here: Guide to mechanical adjustments and maintenance
I checked the laser module using the 5V socket, and it fires. So my module is working.
I flashed the firmware using LASERGRBL as described in the link posted above. Laser still does not fire.
Please post your firmware settings and the detailed layer settings to check them. The problem must be there if the laser is OK.

I tried to run a normal print that i’ve done hundreds of times, and the laser moves to the extreme top right corner, and moves at a tiny fraction of the pace that it usually does.
There are many false values in your firmware configuration. I noted the most prominent errors. If you change these, you should be good to go, I think.
If these have been factory defaults, you have a wrong firmware on the board. But still, this one will work as well. Though, I recommend flashing the one I provide here: Firmware Update & Settings - Diode Laser Wiki This will make things easier during usage.
Edit: you can also try to send $RST=* in the console window, this should reset all values to factory defaults. You can check afterwards if you have the correct values there.
how do I “change the values”???
I flashed the laser with the firmware provided in the link, [v1.1h-custom-S6S9v2.hex] and the laser acted strange, and the laser does not fire.
You change the values either via the “machine settings” window of LightBurn (open “outputs” section) or in the console window by typing $setting=value, e.g. $32=1. One by one, the laser should answer with “ok”.
If you flashed the new firmware, you might need to send $RST=* once, to reset all settings. Just to be sure. Then check again if it’s acting strange.

I typed in all the values by hand, one at a time. And it worked. Thanks for your help.
