I have a chinese 60 watt laser (1200mm tube) The machine was purchased in April 2021 and has had very light usage.
I use the Cohesion3D LaserBoard and lightburn software. I installed an mA Meter. I have my laser power (on machine not software) at 45 and the mA meter never goes over 20ma
Water cooling CW5000
I have have used this no more than 75 hours in total (this is a really small part of my business which I wanted to increase for Christmas)
So very little use
This has been working like a charm, no problems at all until yesterday
It seemed to be missing parts of a fill and the meter at some points showed no current at all even at 20% which is what its normally run at
I have added a couple of picture for you to look at. Not sure why but the line lasering seems ok but fill is just not working correctly
I really do not know much about electrics so if thats an issue I need to be very careful
I am not sure if this is a tube issue (hopefully not) a power issue or a software issue
You’ll need to google search for how to align it. It might not even be misaligned, I’m a rookie and this is just my opinion based on the burns you showed.
I’m assuming you didn’t move the board in between test burns, and as the head get farther out of alignment you are seeing these artifacts. To me this indicates it’s out of alignment. When you increase the power, even when it’s out of alignment, enough power gets by to compete the engraving. At lower power it’s more sporadic. But it also appears to wobble a bit and the missing bits and laser dragging are perplexing.
There’s no shortage of video explaining how it’s done, but please wait until a more experienced member comes along with some advice, because you might make it worse trying to fix it.
But basically everything including the tube need to be perfectly aligned with one another and level. It can be simple or perplexing like my own CO2 laser which is still not operational due to being out of alignment.
Thank you for your answer.
I have checked and the mirrors are all aligned correctly
I also started to do another test after I cleaned the mirrors too and noticed that the error is in exactly the same place (see the last line on the board is missing at the exact same parts in the lettering (it crashed due to I turned on the exhaust vacuum system)
So I am back to the beginning
Tricky this lasering stuff…
