Laser issue Jackpot LR4 - no beam

Software / Firmware Jackpot Board / FluidNC
1

Setting up a Neje E40 laser with external 12v 5a powersupply connected signal wire to gpio.26 on board Also tested gpio.27. I have made a config only for laser. Both lightburn and LaserGRBL connects to maschine and moves it as it should. The laser does not turn on. If I press macro.3 on dashboard it enables laser (M62 P0) and macro.4 (M63 P0) off. I have tested all combinations recomented but I am missing something with M commands and also err: Pin is already used ???

Thanks ! please look:

Fancy!

(Sorry, I can’t help you with your laser :slight_smile: )

Welcome to the V1 forums.
That’s a beautiful machine build! Do you have a build thread here?

Your configuration is invalid. You have GPIO 26 and 27 defined elsewhere besides the laser section.

E.g.

digital0_pin: gpio.26
digital1_pin: gpio.27

You need to remove those.

You also have a laser config with an enable pin. Did you hook up the enable to the NEJE adapter board? (Pics of that wiring would help)

Did you tie your laser 12V power supply return to the jackpot power supply return?

I removed gpio 26/27 from user outputs and it helped. My spindle output is not defined I do not know what that to type.

[MSG:ERR: Laser spindle output_pin not defined]

gpio.26 Yellow wire to laser (signal)
Ground from laser and from powersupply to GRD on jackpot next to .26 (black)

You had that pin listed.
This config error usually happens when you’ve got an extra space or something in your config.yaml. Double check that you don’t have extra spaces/tabs/etc in your config.

Hard to see with eyeballs.

Thanks Got a little further now and a little happier but. Laser lights up when g-code is send from lightburn but only at full power I have tested diffrent S values in LB and in config no difference. It moves to starting point then lights up but I can’t controll output and it dosnt turn laser off in travel, the wood has a line along travel between the two squares that should not be there.

This is the Laser section from my config file.
Your laser may work better if the 100% is set to 1000. I don’t have a Neje, so I’m not sure.

Thanks for all the help. Now it runs as it should and I can finally finish building my lowrider. I have newer done cnc stuff before but when I saw the lowrider on youtube I was hooked and bought a 3D printer without realizing what I was doing. It took 6 weeks to build only starting to learn.

It can work fine either way, as long as both Jackpot and LightBurn are set to the same settings for the max. I prefer 1000 in either, but 255 steps are better than most systems can actually control the level so it really doesn’t matter.
