The Polar has always had a genuine Ruida controller. I didn’t watch the video, but I know they’re not the same, even though obviously quite similar. It was more likely to crash with things near the edge(s) of the work area. Sometimes I could do 2 or 3 things first, but that was less common.

With 1.4.03, it crashed after almost any job.

I only ever had the one crash, which was after the job finished: the Laser apparently wasn’t responding, and clicking Z focus or other controls made Lightburn app crash, or at least that’s my assumption. I don’t have anything that crashes 1.4.01 consistently. I repeated the test 4 times, with and without stopping it halfway through, but could not get LightBurn to crash again. However, upon restarting LightBurn, the laser status was disconnected until power cycling the laser (I also restarted LB). I’m also not sure if any Mac users experience these issues.Īfter my diagonal line test & stop halfway through, LightBurn app crashed, and the laser status was normal (this was after 4 or 5 other jobs). From what I’ve gathered so far, it appears these issues less likely (if at all) to occur for those that use Send instead of Start. You can search for Polar on this forum and see other users experiencing similar issues. I don’t know if these bugs are exclusive to the Polar, but a lot of Polar users have experienced them.

LightBurn 1.4.01 instal the new for mac
