Hi, all; I’ve recently installed my new JTech 34-Watt laser, and made a few test cuts in the 3mm ply I plan to use. I’m having a few issues, and I wonder if anyone has work-arounds. I’m using the VCarve laser addon. My issue reduces to the fact that the app doesn’t allow the addition of tabs to a pr…

Scott, thanks again for your input. I went ahead and ordered some valves. I had to look hard for metal ones, but they are cheap. I’m going to go ahead and call this thread closed, but if you (or anyone else) has comments or suggestions, I’d sure like to hear them.

I would suggest getting a honeycomb table and doing your laser cuts on that. Though I don’t laser cut with the 1F, with my lasers it’s what I use. Generally if your air assist isn’t cranked too high the parts hang out after they’re cut. You’ll still want something ‘sacrificial’ underneath it, most l…

Thanks for the quick response! Please be reassured that my first purchase after the laser was two pair of goggles rated much higher than the ones JTech sent, and I can wear them over my shop specs. There are great deals to be had on EBay. I have downloaded Lightburn’s demo, and as far as I can tell…

I took a quick look at both LightBurn and Xtool Studio and agree those wouldn’t be good solutions, since they appear to add the tabs on output and don’t seem to have an export function that would allow you to modify a vector then export it with the ‘gaps’ in that would represent the tabs. Regarding…

[image] SailorMike: I have downloaded Lightburn’s demo, and as far as I can tell, it’s mainly for use at the machine in real time. Apparently, G-Code files can’t be saved without going through some gyrations. That won’t work for me, as my computer is in a separate room, I don’t want to learn ano…

Are the configuration files for the 1F readily available. I can see from the screen shot that you have a laser config for 1F as a GRBL laser. Would you consider pointing out the link to the setup file or exporting your own and posting it? While I personally don’t need it, for the sake of anyone fo…

I’m so glad I started this thread! I went ahead and bought a lattice that comes with a metal backplate. I’m not sure about the hold downs clearance from the laser head, so I’ll try something else instead. Based on what you guys have said, I’m going to give Lightburn a shot. Funny, I watched a bunch …

Second take… Lightburn, out-of-the-box doesn’t know a thing about your OneFinity CNC. It doesn’t use post processors like VCarve does. So, we have to tell Lightburn about the GCode that our CNC understands, whether we’re using imperial or metric measurements, the size of our work area and where ho…

Tom, your link sent me to an ask permissions page, which I did. Well, I’ve been fooling with LB, and I might get it if for no other reason that I plan to cut out some tiny parts, and I need the tabs, which I finally figured out how to apply. I ran a test program on my machine with my plotter attach…

SailorMike, consider using magnets on your honeycomb pushed up to the sides of your workpiece. They work great for me. Also, I find that Lightburn has a lot more versatility than OF laser add on. The laser power levels are much different in the two as well. OF add on laser power precents are more po…
