Laser stopping mid-burn

Image files attached for reference. Genmitsu Jensoku LC-40. Lightburn 1.15.01. Newbie trying to burn bed grid onto plywood underneath laser.

Problem #1: Laser stopped about 4-5 times during the grid burn. Able to restart with the preview window to finally finish.

Problem #2: Cannot burn numbers. Getting some error messages that I’m not able to figure out. Attached the console log and lightburn project file for anybody that wants to take a look.

Laser seems to work fine otherwise on smaller projects as I’ve been able to burn several images and even cut out the hexagon from cardboard.

I would check my USB cable and connection. Seems like a communication problem.

Well, if anyone is interested, problem #1 was due to the “Standard Serial over Bluetooth link” being assigned to the same COM port that my laser was occupying. It was fixed by assigning that to a different COM port.

And problem #2 seems to have been caused by there being a non-zero number in the “Offset” field below the Serial Number setting. When I changed it to zero, everything burned correctly.

Thanks for the update. May help others with similar problem.
