Hi forum, I’m starting to pull the little hair I have left soon if I can’t solve this
I have OLM3 (ORTUR LU2-10A 10W Laser Module)
Running with lightburn since ~1 year and been working solid, now coming with a problem I’ve not encontered before.
So I recently started to see ‘shadowing’ when cutting / higher power. As you can see in the pictures, I’ve checked the belts / nuts and screws and I can’t feel anything that is out of normal. Alignment is good aswell.
I was considering the lense so I did cleaning, I opened up and cleaned it both ways. Are there more lenses / mirrors further in by any chance?
When I engrave/fill it works like a charm, even when I pull down the power and write texts or such, then it wont show up (perhaps not enough power to shadow/reflect?)
EDIT:
It’s 1 pass, 99% power, 3mm plywood.
As you can see, it’s giving a second line and it drives me nuts.
Not sure if this helps with some more information.
Sometimes I wonder if it’s mechanical, and sometimes I still think it’s lens.
The engraving on the black slate here, it’s done with 5800 mm/m, 90% power. I see no issues / shadowing or such. But this is engraving from one side to the other, back and fourth.
The cutout on a piece of 3mm ply I just did is 200mm/m with 99% power, 1 pass. Here you can see the ‘extra’ line, any clue? Lens? Some screws I’m missing? Faulty laser?
And something that baffles me here is that I see no shadowing after cutting this piece out. Not sure if it has something to do that it’s straight line and not curve/circling. I’ll test that aswell.
But clearly something is off. I will take another look at belt, nuts, pullyes etc. And also check that guide aswell you linked.
Test below is how I place it and the result. Ideas?
I used 1000mm/min and 50% power.
