Hello, lightburn stops in the work

[fjdemontis (fco javier)]

Hello, I am using lightburn normally, and at the moment the machine has started to stop after 90 minutes of activity, what can I do?

[gilaraujo (Gil Araújo)]

I am unfamiliar with your machine so will be of little help

However a few things would be helpful

a) When machine stops do you get any errors in console
b) do ALL jobs >90min stop? or just that one
c) if you run the same job at 1% power does it also stop?
d) what lightburn version and controller (it might help)

I was going to ask a similar batch of questions…

Does the laser module have the ability to turn itself off if it overheats? This isn’t uncommon.

And is what I think @gilaraujo is driving at with the 1% power question.

What power are you running the laser?

Is it this animal?

@jkwilborn

And is what I think @gilaraujo is driving at with the 1% power question.

I tend to use the 1% as a catch all test to validate power issues too. Power adapters can become “lazy” overheat and giveup. More specifically warm up and have a voltage drop that leads to controller crashes that lead to no error halts on engraving.

Plus, a bonus, saves materials

Yes, that is precisely the machine I use, also the machine came with a 40w power laser and they changed it to an 80w laser, is it overheating? how can I solve that?

[gilaraujo (Gil Araújo)]

You must diagnose first
if the job does NOT stop running at 1% it might just be your power adapter is under sized dor the laser output

What is the output specs of power adapter

Also do you have a label of the laser module, it should say there how much it takes as input amps wise

[gilaraujo (Gil Araújo)]

Edit:

if its a 5W output which is what it says
Your power adapter should be
24v 2amps
or 12v 3amps (unsure which it uses)

if its a 10W laser output
Double that
24v 4amps
12v 6amps (doubt is 12v though)

If it is 12v with a 10w laser, the machine is a flyingbear laserman that came with a 4.5w laser.

[gilaraujo (Gil Araújo)]

Maybe i am miss understanding

Originally it was a 5W module, lets call it that
Then they changed it for you for a 10W?
But did you upgrade the power adapter?

If the above is correct, and you did NOT update power adapter that might be why you having issues.

Their website is not clear on specs so i would do the following
a) take an image of the label on the module
b) take an image of the label of the power adapter
c) take image of any specification label on the frame

Then we can double cross specs between all 3 components

I mean, if I change the adapter to a 10A power one, will the problem solve?

Ideally we want to understand the problem first before starting changing things or you will just add more variables on the problem.

So, which power adapter you have now exactly?
What input power does laser state it needs

All this should be labeled and is easy accessibly by just checking

The adapter has a 4A output, which works for a 4.5 laser, but for a 10 laser it would not work.

[gilaraujo (Gil Araújo)]

@fjdemontis

The adapter has 4a output

I would strongl suggest you are precise

What output voltage, what output amperage

By the same token
check your machine and module and check the reverse specification
Which input voltage and amps do they require?

[fjdemontis (fco javier)]

The machine does not say anything, it only says input rating 12v 4A DC on the label

[gilaraujo (Gil Araújo)]

ok so… If we are correct and your issue is power

The same project ran at 1% power cannot FAIL and stop at all

then it would confirm you have a too low output power adapter

Easy test. Once done you can raise it to 50% and defocus the laser too so it doesnt engrave.

if that does not fail either, then is for sure an issue of power adapter
You would need a stronger 12v power adapter, 6-8amps
Would be peculiar though.

[fjdemontis (fco javier)]

Ok gracias

There is a simple relationship between current/voltage and wattage.

You really don’t need to know what comes out, as it states it needs 40W in for the module…

The module itself is 40W / 12V means it will require 3.3A just to run the laser module. This doesn’t include the motors and control board.

Does this new 40W laser module come from the same vendor? I’ve seen many of these and they all used 24V. Is the laser module marked as to a supply voltage?
