I’m new to laser cutting and tried cutting and engraving on plywood - the first cut came out perfect but then I tried to cut the same thing twice, but both came out wrong. Is this due to the laser getting stuck whilst moving or what might be the issue? Had a similar issue when engraving a photo, where it was fine, but then halfway up the imag...

LB 1.4.04 GRBL on Win10 via USB.Not sure if I’m missing something, but I have been able to set up any project with multiple fill layers, all set to “fill all”, so that it scans all layers in one pass.I can achieve this if I flatten the fill layers into a single layer.For example, I have four fill layers with the only difference b...

I doubt this pertains to Lightburn directly but I’ve tried other groups and zero help. I have an OMTech 60 2028 red n black. I find that it if set multiple passes on a cut line it ‘appears’ to be ok. if i set multiple passes on an engraving, the head goes back to origin then proceeds to perform second pass. It’s always off j...

I currently have my laser engraver (atomstack a5) out in my shop, and it requires a USB connection, as I only have one computer I have to leave it out there until it is finished. Is there any laser engravers that I could hook up to my computer (whether by USB or wirelessly) send the commands to it and take my computer away from it.

Using a basic rectangle as an example, how can I remove part of one of the lines; i.e., cut an opening in the side. Also can I drag a corner to change either the shape of the rectangle or make one of the walls go at an angle?

Just updated Lightburn (not used it for months while moving from one location to another). The version I downloaded is 1.4.04 running on Mac Os Big Sur version 11.7.10. Homing is correct. Z direction is correct. Jogging in X or Y direction is wong. Both directions are opposite to the expected. I engraved a project and the laser worked fine. The ima...

Christmas ornaments for example, kerf so tight, having to manually push out most small pieces. So I decided to raise laser height off work, thereby making a wider beam thus wider kerf. As I understood the kerf offset, it just moves the cut, not widening it. I am buring through on multiple passes, work looks great, just not seperating like I want. I...

Is it possible in Lightburn to create an array or object in a circle like in the image?Now that I type this, I suppose I could do it with a rotary pointed up toward the laserBut is there a way to create an array and curve it into a circle like you can with text?

I recently bought a new 100w power supply for my 90w Cloudray tube. The power supply has a remote adjustment for power. I find that I cut paper to cardboard to engrave and cutting that all take different power settings. I don’t like to blast thru materials at full power. So from Lightburn I could need various files of the exact same vector to...

Hi there!I wanted to see if I can have some help with my engraving. I’m using an ORTUR laser to engrave my yeti cups. I’ve engraved over 30 WHITE cups and everything turned out fine until I needed to engrave a black one. I don’t understand why it’s not working. I decreased the speed and set the power to a higher setting. I e...

Since LB can not create a spiral easily, I made one in Inkscape and then placed it in LB.I then applied text to path, which works, but its written from the center out.I need it to be written from the outside.But nothing I do will get it to do that.I figured the answer to this would be the Set Shape Start Point tool.Which if I use that, it will plac...

Hello. I have an OML3 and would like to know how to control air assist from lightburn so the air flows when cutting and stop while engraving without me having to turn my pump on and off manually. I need to know about configiuration and hardware needed for this if it is possible. Thanks.

I’ve been doing experiments with Image engraving. I’ve done a lot of my general fill engraving to high DPI (usually as high as 600). But two things occurred to me. 1.) after doing a proper DPI test based on an Imag-R file, I found that my machines DPI is roughly 242-254. Though, I just realized that this was based on Image Pass-Through ...
