Laser moves, laser does't fire

tried to burn txt It would go to position, the laser would lite but wouldn’t burn!

Can you confirm that you updated S Value Max to 255 in Device Settings? Doesn’t show that in your screenshot. Make sure you do this first or else you’ll have a bad time.

This is likely an issue of your cut settings. Power too low or speed too fast.

This is what I wrote in a previous post. Did you make any adjustments?

What power setting is your layer set to?

Where do I find that

Yes

Set max to 100% min was at 20% still no burn
set min to 50% now burn
Is that normal?

[Bill_L]

Sorry I Didn’t see this earlier

Send a screenshot of your cut settings. I’m guessing you are going too fast. It’s also apparent that your laser module power is fairly low given how high you need to set it to get a visible light.

In Inch

In mm

It says 3000mw
Do you mean 3000mw is low or that it’s on its way out?

@anon88048707

I’d cut that back to 85% power, and 600 mm/minute, otherwise you’ll be replacing your laser module soon. (mine lasted for 285 hours under this sort of abuse). Your mileage however, may vary.

That should get you through 3mm plywood (with air assist) with very little trouble.

I’ll give that a try

In mm

O…K
I got those Backasswards mm/in

@anon88048707

3,000mw = a 3.0 W laser.

This is a perfectly capable laser for engraving … and even cutting very thin material, such as cardboard, paper etc…

But don’t expect it to burn through 25mm thick hardwoods.

No prob
No I wasn’t expecting that

[Bill_L]

@anon88048707

that actually says: inches / minute)
(and the other one says: millimeters / minute)

Q: have you added an air assist nozzle / air pump to this system?

What I meant … I put the mm capture under in Inch and the inch capture under In mm

Air…Not yet

I got this a few days ago and just got it working with the help of berainlb

What are you trying to engrave to? 1794.4 mm/min is on the higher end of speeds for engraving with a 3W laser but I’d expect it be making a mark at 100% power on most materials.

Keep reducing speeds until a mark is made. That will give you a sense of how much power is required.

You may want to try running one of the many different test patterns that are available on this forum. Will help you understand effect of speed and power.

[Bill_L]

@anon88048707

Is your plan to engrave, or cut?

Eventually both … I do know there are limitations with 3w, so that’s 1 (of Many) learning curve, till I upgrade to more wattage lol

Eventually Whatever I can lol
That is the speed that showed up after installation, That’s the first time I’ve seen it… I think…

I’ll do that
Is there a thread for the test patterns?
I have a very good understanding on power and speed (I weld, same idea but different lol)
Now comes the Fun Part … Experimenting. I’ll keep the fire extinguisher Right at Hand and Not walk away for more then 30 Seconds

[Bill_L]

@anon88048707

At least you have a path, and can get one hurdle at at time cleared…

Thank You for Your help

[berainlb (PY)]

@Bill_L

Is there a thread for the test patterns?

There will be many if you do a search. I don’t have any specific ones referenced.

[Bill_L]

Thank You again for your help

[Mattl (Matt Langlois)]

check out the Louisiana Hobby guy. I found him to be a great help

[Bill_L]

I will
Thank you
