This is actually a continuing problem. I have the Ortur LM3, using Lightburn software 1.2.04 with a windows 10 laptop. I have the LM3 plugged into a socket with no other items plugged into the same room. I have run an extension cord from another room for the laptop. I have run another extension…

I finally fixed this problem with the help of all of you. I attached an upgraded USB I disabled firewall I disabled the sleep feature I installed the updated software… Nothing changed! Then I found this: I stumbled across this today, it may help you: ORTUR Laser Master 3, Connection Problem S…

This really isn’t a LightBurn issue. Here are the steps to install the firmware Upgrade on the OLM3. Long press on power button, keep holding the power button. Press the Reset button once. Release the power button, and you should see Red→Green→Blue flashing sequence. Drag the upgrade file to "Ort…

That sounds incredible. I will def give it a try this week. Thanks.

[image] Claude: Redirecting… Nice! I just posted about an LM3 issue I have with it powering off mid-job. I’ll try the grounding and see if that improves my situation.

Claude and Robert Engel I believe you are both posting to the wrong thread. I have not had any issues with finding my sd slot. Confused…

I’ve been having the same issue, sort of. LM3 stops in the middle of a burn. But for me it’s because it’s lost Wi-Fi connection. LightBurn seems worse than LaserGRBL, but they both do it. I’m wondering if it’s a power quality issue with the LM3. I live rural, and I know my power out here is bad. …
