1 week of usage and the laser seems to be losing power?

[thehodge (Dom Hodgson)]

Hey folks, this is a strange one, I have the Ortur Laser Master Pro 2 (S2) that comes with the 10W LU2-10A.

It’s been running fine until I upgraded to the latest firmware (as I bought the enclosure with the fan and light)

Since then I’ve noticed that the cuts have been a lot less powerful, at first I thought it was because the unit was powering both the fan and light so I moved them onto a separate circuit but no difference,

I then thought it could be a dusty lease so I took some cotton buds and alcohol and did a bit of cleaning, no difference

Finally I added an air compressor with air assist but it doesn’t seem to have made much difference.

Here is a LightBurn materials test a few days ago on 3mm plywood

And here is one just a few minutes ago using the same wood and settings (it does have an aircompressor added)

Just for reference here is a materials test for 2mm plywood

Now if these results are what is to be expected for these materials (and we just had to burn the laser in) then that’s great but I just wanted to make sure I’m not missing anything or I’ve forgotten a step in my debug process?

Hello, clean your lens. You will see a white spot on it, you need to wipe it with isopropyl alcohol.

If the firmware update was causal, this could be the result of a mismatch between the Device Setting for S-value max and the Machine Setting for $30.

In the Console in LightBurn request the Settings from the engraver by typing the Following:
$$
then press enter.
Note the value assigned to $30.

Click Edit, Click Device Settings

Compare the value assigned to $30 to the value for S-value max.

These values should be identical for almost every use-case.

Hey @parkoof, I tried that before posting but I thought I’d try it again!

Here are is another material test (and a picture of the laser after this test to show there are no white marks on it)

If you can think of anything else for me to try and please me know!

[thehodge (Dom Hodgson)]

Thanks @JohnJohn They are both set at 1000

Your test in 2mm plywood seems to be much cleaner.

Did you adjust your focus for the thicker plywood?
Is the Plywood from the same source?

[thehodge (Dom Hodgson)]

When you say focus do you mean do I reposition the laser with the attached leg because if so then yes.

The cleaner burn might be something to do with Air Assist I’m still trying to work out how that effects cutting vs engraving.

The 3mm is from a different supplier but compare these two 3mm plywood material tests, this is the same supplier and same batch.

This is from last week

This is from a few minutes ago

I’m ignoring the burn marks around the engraving but it’s more the cutting power has reduced dramatically, if these results for 3mm ply for this laser are expected then I can work with it but it’s just the dropoff from that first picture is a fair amount.

Great.

Is the air assist being used in both material tests shown in your last post?

@thehodge

The cleaner burn might be something to do with Air Assist I’m still trying to work out how that effects cutting vs engraving.

Air assist can reduce the scattering of the laser from smoke and debris. It makes very clean cuts and allows higher cutting speeds or lower power levels to be used.

[thehodge (Dom Hodgson)]

The first one had no air assist, the second did.

I’ve just run another one without the compressor attached and here are the two together you can see that the cuts are a lot nicer but still much less power than last week?

[Djodjotje (Erik Janssen)]

Power supply still OK ?

[thehodge (Dom Hodgson)]

the light is still on, there hasn’t been any cracks or bangs of it, I don’t have a spare to test though, Happy to order one and see if that makes a difference but I get the feeling I’m getting close to a Ortur support ticket.
