2023-05-2233010Having a issue wit line offset in lightburn. I got the offset where i wanted for the speed/power i use for NWT It looked great. Then I switched to doing painted glass different power/speed. Set the line offset for that speed it looked great. went back to doing NWT and the offset is waaaayyyyyy off now. Now that I have 2 different speeds set up do I...
2023-05-2238910For example, if I cut out a square and the cut begins at the top left of the square and cuts CCW 3 times, the square cuts out fine, but there’s almost always a little material left at the top left where the cut began (which stops the piece from dropping free after the cut - annoying). Not enough material to justify an entire new pass (would a...
2023-05-2224510According to Longer, my Ray 5 10W laser has a maximum speed of 10,000. I don’t see any speed difference between 5,000 or 10,000. Doing some research, I know that when in console mode and I enter $$, I get a string of settings. According to everything that I have researched online, $100 & $111 relate to X and Y axis speeds. When I entered ...
2023-05-2232910Hello, I am using foxalian mastur 20watt laser. before upgrade i was not having any issues, now with 1.4 upgrade its burning teh hole frame not just the image. i was doing a gray scall test and it did the hole image. i have posted the $$ below… i also confirm S value is set to the same has $30. i have looked at other posted and still no help...
2023-05-2223010I opened (and also imported) an SVG file and found out the hard way it had scaled the original by about 75%. I saw elsewhere in the forum that this might be fixed by changing the units in the import setting dialogue. The contributor from Lightburn said to change under Edit>Settings using the file dialogue. That doesn’t seem to exist on my ...
2023-05-2226710The first generation of industrial blue lasers based on semiconductor laser diode technology was first launched in 2017. Since then, these lasers have mainly been used in copper and aluminum applications such as welding and 3D printing, which benefit from the increased absorption of (infrared) lasers relative to infrared. Even so, the brightness of...

2023-05-2038910New here, new laser. 10W Amazon/China, called T1 4045)Jobs often ‘wander’ and must be stopped or the machine crashes into a rail. This does not happen every time.Could this be a loose belt? Or deeper? Thanks
2023-05-2024510Is there a way to increase the laser position time it stays active? It seams to cancel itself right before I click. Example: I click a location I want to verify, go over to the machine and check laser head position, return to lightburn when laser position button is still active, but then sometimes it deactivates before I click the next location I w...
2023-05-2037210When I purchased my laser and downloaded the LightBurn software, version 1.4, my laser did not seem to be cutting very powerfully. I contacted Longer support and they indicated that I should set my S-value max at 1000. When I did, everything I engraved seem to be too powerful and dark, burning a lot of wood material. So I scaled it down to 550. See...
2023-05-2022210I am looking for help.I am trying to make my setup process a little easier but more importantly more accurate.I would love to be able to put the object I am going to burn in the center of the work area of my Ortur Laser Master 2 and import my design and use the same center point to center the design and then start the laser.Can :Lightburn be set up...
