Howdy Folks …
I am in desperate need of help. Been fighting it for 3 weeks.
Bottom Line: My laser will not fire through C3D board. Attaching picture above.
If I jumper G & L through the back of the C3D 4 pin connector (red line), it fires. Made sure pins were pushed all the way in.
If I jumper from FET- to the top left screw terminal right pin (green line), It does NOT fire. I screwed the wire in, not just touching screw heads.
Using Lightburn, head moves as it should. In picture, homing wires are removed for simplicity of picture.
Using Lightburn, if I hit the optional Fire button, the laser fire light comes on (blue cirecle) but Laser does NOT fire. Brightness of LED depends on % entered. This is the only time I have seen this LED come on.
Status LEDs are VMOT-Red, 3V3/L4/L1-Green, L2/L3-Flashing Green.
Due to my fault, I was forced to replace the tube & LPS. Went with 50W tube & MYJG50W.
I did NOT regenerate the firmware on the SD card.
Thank you very much in advance!
