Can't even cut a simple 3x3 line grid. When cutting a letter "a" (not pictured) the inside is misaligned, too. Please help I have the V4.2.7 silent board, with unmodified Marlin version unknown. Screen says it's 1.0.1

Hello,

I would really like to use this software to run my cheap laser attached to ender 3 pro. Unfortunately after days of set up, it cannot handle even simple shapes without mysteriously being very inaccurate, messing up a simple letter “a” drawn in LightBurn, where it messes up the inside bit of the “a”, as well as disconnecting curves.

I think, because of the log, it is an issue of communication between the software and the printer board where some of the language gets garbled. G-Code version? Not sure

Please? I think it’s a g-code issue

I replied to your reddit post, but you need to uncomment LASER_SYNCHRONOUS_M106_M107 in configuation_adv.h on Marlin 2.0.8+
