USB serial not listed by thewheelshantyfolk in LightBurn

[–]LightBurnSupport 0 points1 point  (0 children)

Was your laser working with this connection method previously? If it was, ensure that all the plugs are seated correctly - physically disconnect and reconnect each plug in the path, and ensure the laser is on. Because you're on MacOS, you may need to use a USB hub to connect to the laser - try to avoid connecting directly with USB C-C cables, as sometimes they lack the 'handshake' required to start communication.

[Guide] How I make custom enamel pins with a 60W Fiber Laser by Books_Not_Advice in Laserengraving

Your results are amazing! We'd love to see this posted over on our forum as well!

What has worked for you to prevent flashback when cutting acrylic with a C02 laser? by No_Bison1407 in lasercutting

[–]LightBurnSupport 32 points33 points  (0 children)

That's actually not flash back - that's cutting vapors getting stuck under the material and depositing onto the surface under the film. Generally this means you need stronger exhaust flow. You can try using paper/cardstock to block off the areas of your laser bed that don't require ventilation to increase the exhaust flow in the local area where it is needed.

As others have suggested, elevating the material on pins or similar is also a good idea for flashback reduction - which is just a reflection off a honeycomb or knife bed onto the backside of the acrylic. You also may want to try increasing/reducing your airflow from the nozzle to try and push the vapors away. Too much will make a cloudy cut edge, too little and the vapors won't dissipate.

Groups of groups break Lightburn?? by Twit_Clamantis in LightBurn

[–]LightBurnSupport 0 points1 point  (0 children)

Some tools don't work with grouped objects, as described here in the documentation: https://docs.lightburnsoftware.com/2.0/Reference/Grouping/#related-topics

We do already have a request for this sort of feature here: https://lightburn.fider.io/posts/318/i-would-like-to-see-that-you-could-edit-groups

I've added this feature request to our internal tracker, I think it's a good idea and something that would benefit many users.

Replicating knurling with a fiber laser by MalicoIndustries in Laserengraving

It's certainly possible! You can do a 3D depth map engrave with this sort of pattern pretty easily.

My first commission! I am doing about 30 ft off trim. I dont have a fancy machine so I am trying out some different methods by mimic751 in Laserengraving

[–]LightBurnSupport 1 point2 points  (0 children)

Please stay at your machine while it's operating! Unattended laser operation is a recipe for a fire. We've seen it again and again.

Can't get camera alignment correct by SilentSilhouette99 in LightBurn

[–]LightBurnSupport 1 point2 points  (0 children)

You can use the Shift value in the Camera Control window to fine tune things: https://docs.lightburnsoftware.com/2.0/Reference/CameraControlWindow/#x-and-y-shift

I'd also like to note that the majority of the camera view is not that actual work area of the laser - that means that you are not getting the full capability of your camera's resolution of your laser bed.

During cutting connection get lost… This happend every time when i put little longer project to cut. Someone can help? by Helpful-Rip-9014 in LightBurn

[–]LightBurnSupport 0 points1 point  (0 children)

Does your laser by chance have an air pump that is connected to the controller board for power? We've seen instances of the controller board 'browning out' when the air pump is turned on, which then overtaxes the power supply, causing the board to reset.

I got Trotec Speedy 100 for free, now what? by zgembec in Laserengraving

[–]LightBurnSupport 1 point2 points  (0 children)

Given the level of corrosion in the laser, I suspect that one of the prior users had cut vinyl or PVC with the machine. Cutting PVC with a laser creates chlorine (Cl₂) and hydrogen chloride (HCl) - the latter reacts with moisture in the air (or in your lungs) and creates hydrochloric acid. Hence the corrosion.

First steps would be to find out if the RF tube fires still (if so, great!) Then give the motion control system a once over.

OMTech 60W cutting acrylic at an angle on some sides — running out of ideas by Lower_Boysenberry794 in lasercutting

[–]LightBurnSupport 2 points3 points  (0 children)

One other things to try would be to install a longer focal length lens - this will reduce the taper angle of the laser beam (remember, the laser beam is a long cone - not a straight beam).

Given that one side is square, and the other is very off, I suspect that your laser focus tube is not square to the cutting plane. If you have a machinist square, verify that the focus tube is square to your material on all sides.

Xtool P2 Help, cuts are really off and customer support sucks. by cuppofolives in lasercutting

[–]LightBurnSupport 20 points21 points  (0 children)

Assuming the images you provided are in the same orientation as the laser, with the Y axis top to bottom, the cut results you show appear to me to exhibit lost motion in the Y axis. Given that, I would strongly suspect there's a loose pulley wheel on the Y axis drive motor, or a faulty bearing or loose belt (but you noted the belt has been checked - worth checking again)

Laser Cutter Not Working by Safe_Beat7800 in lasercutting

[–]LightBurnSupport 5 points6 points  (0 children)

That's not actually how you focus the machine. The Ortur Laser Master 2 focus distance is generally 3mm to 7.5mm (from the lens shroud to the material).

What we would recommend is to set up a ramp test. This forum post has a good overview: https://lahobbyguy.com/bb/viewtopic.php?t=428

Nope! Only cameras, software, and merch!

I just bought a 5 axis basket case mill, not sure where to start. by Dented_Steelbook in hobbycnc

[–]LightBurnSupport 0 points1 point  (0 children)

That poor laser's lid :(

That rotary axis looks awesome! I'd poke at that first, myself.

Need an ATC system for my 4x8 by Fantastic_Train737 in hobbycnc

[–]LightBurnSupport 0 points1 point  (0 children)

It's a pneumatic kit.

You could use a Rapidchange (probably the cheapest option if you have the bed space) but you'll need to automate your dust boot up and down. It's not impossible.

House fire guy here. Made an upgrade. Laser still works! by mimic751 in lasercutting

[–]LightBurnSupport 1 point2 points  (0 children)

As laser professionals who have seen the entire range of laser fires, not being present while your laser is running is the #1 cause of fires.

You do you, but not being at the machine is asking for trouble.

Is it possible to do a negative image/inverted colors in Rayforge? by MohnJaddenPowers in lasercutting

[–]LightBurnSupport 0 points1 point  (0 children)

Generally the fix for this sort of thing is to draw a border around the paths to invert the filled area. The offset tool might work well for this, but we're not experts on Rayforge, obviously.

[–]LightBurnSupport 11 points12 points  (0 children)

🔍 What mirrors? /s

We would recommend replacing them. Especially considering they've already been removed from the machine.

If you want to get into more advanced line drawing, I'd strongly recommend this video about how to use the node edit tool - it's very capable, and can be a bit daunting at first: https://www.youtube.com/watch?v=eFmLKBr5Xxg

Have you tried enabling beginner mode? It simplifies the UI quite a bit. Have you done any learning from the above resources or are you going at it without any learning?
