I’m trying to get my machine to print a gray scale image. I seem to be having an issue getting the setting dialed in?? When I printed a scale test it seemed to be a failure.
My machine is
Rambo board 1.3
Running Marlin firmware
J Tech Photonic 4.8 watt laser
When I run a test program it is only printing at the 100% power and doesn’t seem to translate any of the gray scale in.
