The framed layer burns exactly as it should, but the text layer, that is centered in the first layer, can be off by a few centimeters or just burn a straight line. Everything looks good until I start the burn. I home the machine before every burn and reset the origin, frame out the layer with the laser on, go back to origin and start the burn.

The rectangles are centered inside of each other, largest to smallest. The layers consist of 3 rectangles and text in the center of the smallest rectangle. I am getting inconsistent layers and missing layers.I closed out LB with the machine on and the other way around. I read in another thread that if I turn LB off and then back on it should correct that. When I go into Machine Setting, I get only get “Communication with Controller Failed”.Does LB automatically default Marlin as GRBL? When I tried to edit the settings to Marlin, the Machine doesn’t respond. When LB scanned my machine, it detected a GRBL-M3 (1.1e or earlier), I thought it was odd because it’s Marlin firmware.

I am able to control the printer and run burn jobs, but there are rabbits running around. I’ve searched the forum with varies key words and nothing is turning up, maybe I’m searching the wrong topics.

There are a few rabbits that I’ve been chasing for the last few days that I’m confident are not machine issues. I’m using Windows 8 Enterprise 64 bit OS. This is my first laser and I’ve only worked with Marlin with my 4 3D printers. I’m running an SKR Pro 1.2, TMC 2225s, Atomstack 5A 20w (PWM), with modified MPCNC Marlin firmware and LB 0.9.24. I converted a spare 3D printer to a laser engraver. I posted this in the LightBurn forum, but haven’t gotten any responces.
