New Laser Still Burning While Traversing White Space

LightBurn Software Questions
1

OK, so I removed the OxLaser 2500mw that was giving me the above issues.
I went directly to SainSmart and ordered a new 5500mw laser that I was advised was compatible with my SainSmart 3018 CNC.

Well I plugged in the new baby and tried to engrave an image.
Guess what? The same issue…Continues to burn in the white area while traversing.
any suggestions?

This new laser has a separate controller with fan that is wired between the Woodpecker 3.2 control board and the laser itself.

No matter what I try to change in the Lightburn setting, nothing changes.

I need some serious assistance please.

“No matter what I try to change” - can you elaborate on what you’ve actually tried?

Your profile lists 1.1h as the firmware, so what are the settings on the firmware? (type $$ in the console and press enter, copy & paste the output here)

Here are the firmware settings you requested.

Check this to make sure it’s also 255:

Hey Oz,

I checked my settings and I had the max power set at 1000 so I changed it to 255.

No change in issue, still burning in white space while traversing.

Getting frustrated.

The only thing I can suggest at this point is a possible wiring issue. Your settings look correct.

Hey Oz,

I have read is a couple of posts on the web that this company’s wiring has been reversed.
The posts state that the PWM and GND wires are reversed.
I hesitate to swap them as I don’t know what it would do to the Woodpecker board or laser.

ok moi aussi j’ai un problème avec le traçage installer sur windows 10 et imac et ca fonctionnait tres bien mais la les 2 ordi font le meme bug et avec le programe GRBL tout fonctionne bien assez bizzar non…que faire…

This is your problem. Your controller is not in laser mode, which you set by $32=1

Voilà votre problème. Votre contrôleur n’est pas en mode laser, que vous définissez par 32 $ = 1

11

Pierre,

Laser mode certainly is set to $32=1

12

So, The laser is ignoring M5 in the G-Code.
How can this be fixed?

13

I would contact whoever you purchased the board from and see if they can help you troubleshoot. It doesn’t seem to be a settings issue, so my guess is wiring or hardware.

I have a K40, that came with the M2 Nano board. I replaced it with the MiniGrbl.

After the installation of the MiniGrbl was complete, I decided to tinker a little bit with the wiring. I installed a 3 way switch, so I can have the laser activated by the Grbl using the PWM wire (for cutting jobs), or have it fired using the original K40 wiring (to be able to use the TEST button, for mirror alingment, for example).

However, if I send a design from LightBurn when the switch is set to the original wiring, the laser will be always on, even on blank spaces.

Hope this contributes to shed a light on the problem.
