The most interesting part of your output is the two longer traverse (slightly diagonal) lines are not engraved. I found the link, read it, and edited your response to include the Hyperlink. Am i missing anything from the Lightburn software?

In other words, i got white letters and black shadow outlines. It looked like it was etching what the preview window showed as laser transverse movement instead of laser burn. Clicked run gcode which opened the saved gcode and instead of etching the words, it etched the outlines and the shadows around it. Saved the gcode, opened notepad, replaced M106 to G6, saved again.

I checked the preview window how it will be lasered and it checked fine. Problem: I imported the bmp file (pendant 5) which is only a text image, simple. I have read the old forums related to this machine and problems to fix and one of them suggested using the Knutwurst firmware Marlin v1.4.4 (which i haven’t yet) and replacing M106 to G6… So I got the Lightburn Software v1.2.04, on a 30 day trial. I think the sd card reader on the Mega Pro is kaput. I have been etching with only the sd card on bmp files for a while, and now the sd card reader on the machine no longer reads any bmp files.

Hello, I’m new here in the Lightburn Forum, so I’ll try to clarify my problem(s):įirst, I have the Anycubic Mega Pro with laser attachment (1500mW), Marlin Firmware v1.2.9.
