Problem/ Question: Converted my K40 last October. I’ve used it 15 or so times since then. Fired it up the other day and the control still homes the machine, moves the axes, triggers air assist, but won’t fire the laser.
The laser does fire if I use the test fire button on the physical control panel of the machine.
The control thinks it is firing the laser as shown in the console, but the Laser Fire Status LED on the corner of the LaserBoard does not light.
Removed the board from the machine and have it on my electronics bench. PSU is connected and USB to computer is connected.
Placed a meter in continuity mode across the 24v and GND on the laser connection at the board and ran a test program as well as used the test fire button on the move tab. No continuity during firing, or when not firing.
PSU that came with the board is outputting 24v as expected, all other LED’s on the board are lit solid and/or flashing as described in the troubleshooting documentation.
Seems to me something has died. Inspected the board under the microscope and no obvious signs of damage or magic smoke. Solder joints look good. Nothing dropped or cold.
If there are any test points or locations on the board where I could hook up my scope to sniff out where the signal (see if the SOC is actually sending the signal in the first place, etc) let me know.
If not, seems a pretty clean case of: it probably needs to go back to have you look at it.
I look forward to hearing back. Thanks!
