Country: USA | Posts: 373 spyder62 Crew Chief Posted - 02/23/2021 :  12:28:59 PM       with only 20 watt even cutting 1/16 basswood will be slow. Anything harder will take a few passes at least. plus being open like that you will need eye protection from the laser beam. rich In my many years I have come to a conclusion that one useless man is a shame, two is a law firm and three or more is a congress. --John Adams Country: USA | Posts: 681 on30vince Engine Wiper Posted - 02/23/2021 :  1:02:05 PM     I won't be cutting any thing thicker than 1/16" possibly 1/8" basswood I expect to make multiple passes. thanks, Vince Country: USA | Posts: 373 deemery Fireman Premium Member Posted - 02/23/2021 :  1:09:43 PM     What does that laser use for a design program? Make sure you don't have unexpected additional software expenses to be able to run the laser... dave Modeling 1890s (because the voices in my head told me to) Country: USA | Posts: 8840 on30vince Engine Wiper Posted - 02/23/2021 :  1:29:14 PM     Dave, I'll be using LIGHTBURN. Vince Country: USA | Posts: 373 MarcusF Engine Wiper Posted - 02/23/2021 :  5:20:48 PM     I have no experience with that cutter, but I've had a diode laser for a few years, and have had a lot of success with it. Most of them are the same, built around an Arduino-based controller board. I would approach that "20W" with some skeptecism, as these little diode modules (especially at this price point) are really only good for about 7W, and even then maybe continuous. The higher-powered diodes also sometimes don't produce a round spot, so you wind up (even with the best of focusing) with a kerf that's wider in one direction than the other. I've found making a spoils table by placing the work on some sort of honeycomb improves the cut, both speed and cleanliness. Adding an air assist will improve your cutting speed, and give you a cleaner cut as well. For thicker material, you'll likely need to do multiple passes, and having a z-axis keeps the laser focused at the cutting depth. Without it, you wind up with a beveled kerf as the cut gets deeper but the focus point remains at the surface (assuming that's where you set it to begin with). There's a good community at www.benboxlaser.us for these sorts of machines. I haven't played with Lightburn, at the time I got mine, I found BenCutLaser and T2 were the best available for cutting and engraving, as the Benbox software that came with the lasers was, ahem, fiddly. ;) I'll have to check it out.

Country: USA | Posts: 373 MarcusF Engine Wiper Posted - 02/24/2021 :  08:31:24 AM     I can't speak to the G8, but I did find a 3-element lens provided cleaner cuts than the single-element that came with the laser. Is that one focusable? Some of the higher-powered modules are fixed-focus. Country: Canada | Posts: 114 on30vince Engine Wiper Posted - 02/24/2021 :  09:30:42 AM     Yes it is focusable. Vince Country: USA | Posts: 373 Craig H Fireman Posted - 02/24/2021 :  5:11:21 PM     Never seen you Post Any of your modeling on this Forum at all? So just wondering what you would use the laser for? Country: | Posts: 1814 UKGuy Fireman Posted - 02/25/2021 :  12:02:28 AM         I need to get my laser out of its delivery box, it's been sitting unopened in the spare bedroom for 2 years, I got a 40W with several upgrades from the the basics for the, lens, head, cooling, air assist, x,y,z bed, etc... I really should get that thing out and set it up to play with sometime soon, now I'm doing some modeling again.
