I was able to cut a 10mmX10mm square using a 7 Watt Longmill Laser after about 30 passes at 100 mm a minute using 3mm Birch plywood. The secret is to get the laser in focus. I use a "Ramp Focal Gauge from Lensdigital" (which is pricy and you could probably make your own.) Some material cuts better then others. I can cut cedar in 3 passes and felt in one pass. I just ordered some smoked acrylic 1/8" thick and will be trying that next week. I promised to make reindeer in February and will probably have to cut it using a 1/8" CNC router bit. I will keep you updated and let you know if I can cut the smoke acrylic in a couple of passes.

Nice video, and I really like the versatility you have being able to switch between the router and laser! Speaking from experience, having a good air assist nozzle greatly increases both the quality of engraving, and the speed of cutting with the laser. The advantages are many: when engraving, the stream of directed air blows smoke away from the laser lens so that it never fouls; when cutting, the air stream functions as mentioned, and also clears out smoke and charred material from the cut, giving the laser an unobstructed path to fresh material still needing to be vaporized. Although I'm using shop air as a source with a regulator and water trap, it seems like a tiny aperture on the nozzle is MUCH more important than having a powerful supply. I can put 150psi to the nozzle, but this breaks things, and there really isn't any increase in efficacy above 15psi. Using a 5000mw, 445nm laser module at 95%, I can get thru most 3mm plywood in 4 - 6 passes @ 500 - 750 mm/sec.

A 7 watt diode laser should be able to handle 3 mm laser ply fairly easily. I think the plywood in this video may have been regular ply that's typically bonded together with formaldehyde based glues rather than the urea based glues used in laser friendly plywoods. Formaldehydes are hard even for relatively powerful CO2 lasers to cut through, whereas ureas are easy. You can tell the difference by looking at the glue layers between the plys, formaldehydes are dark brown/black, ureas are white/clear.

Given how close your laser is focused to the wood, I would try to cut a few passes, then lower the laser before making a few more passes. Also, the soot left from the laser should be easily sanded off or you can mask the area before cutting.

I'm using a 2.5 watt Eleksmaker laser and had the same issue of not being able to cut through even 1/8" plywood. I recently added air assist to it and it basically turned the laser into a blowtorch. It blows all of the charring out of the way and makes the point where the laser contacts the wood a lot hotter. I noticed that the cut is cleaner and finer as well. You might give that a try. I'm now able to cut through 1/4" wood in 2 to 3 passes. One pass on 1/8".

I have watched a bunch of diode laser videos on youtube and many have the same results you found. One common thread is that the actual power of these units is all over the place when properly measured by a precision meter. Jtech has a good reputation but it is still hard to know if you are actually getting all of the rated power. I also hear that your mileage may vary between brands of plywood owing to the different adhesives used. I suggest that try some 1/8th crafting basswood and see if you fair a little better. Also, just as jsellers202 mentioned, dropping down a touch with each pass would seem to be a good idea to keep the laser focus at the level where the actual cutting is happening. I keep looking at lasers and I really want one.

@Hernandezjv2 3 жыл бұрын
Paw Paw, you may want to try dropping the laser down a bit after each pass. Your focal point for the laser changes with each pass, if your first laser pass/cut removes 1mm of material your focal point for the second pass is 1mm lower than the first pass. You may want to also cut at 100% speed up a bit so you don’t burn the material. Also be careful not to crash the laser into the surface of your material.

@charlesbrewer6552 2 жыл бұрын
This is what I think. I am just starting with my diode laser but from what I have learned so far the focusing is critical. As you cut deeper the focus goes out. By dropping the z axis down to equal the depth of cut, quite deep cuts should be possible with multiple passes. I will find out soon because this is what I want to do.

I have a 6W opt laser that will cut thru that with no problem. When using lightburn you have to enable your z axis and step-down on each pass. For plywood I usually step down about .25mm. Number of passes would be thickness/.25 or 8 in this case. You can play with speeds to try and find a clean cut that will cut .at lease 25 on each pass but not burn around the edges. Different materials my cut deeper than .25 on a pass or less than .25. This is hard to measure so its hard to figure out. My lasers shield sits 35 mm (60 from the lens) off the surface of the material I am cutting but it is mounted beside my dewalt 611. The spindle sits lower than the laser, so I have to make sure it can step down the thickness of your material without the spindle. (remove bit) or the laser hitting anything. If it does I have to remove the spindle. Lightburn can also be told to raise or lower the head more on the first pass and continue to step down from there. I assume this could be used if your your material burns around the edges too much on the first pass. The manual says this can be use for deeper cuts which I don't really understand. I have aways left this at 0 mm and not had a need to use it. Love the channel and have learned a lot of things watching it.

The problem is that once you make the first couple of passes you are trying to cut through a layer of carbon laid down by the previous cuts. The layer of carbon is much harder to cut through than wood. The more cuts the more carbon. If you can get things lined up correctly you can try and flip the piece and cut from the other side, this should double your cut depth there are videos on how to do this on youtube. It involves both software and jigs for alignment. Multiple cuts will work better on something like acrylic because they do not create a carbon layer.
