True 8bit photo engraving on chinese laser cutter - maybe a worlds first?
I see and also can I know which version of Marlin is that? I am currently using 1.1.0 RC7.
That will be great and I will for your update and test. I am thinking with the higher PWM resolution,the print out will be nicer? :)
I only have access to a 250mw LD over my place. It is kind of restricted to get higher power LD. I had tried engraving a photo on wood using the image2gcode software but it turn out that the whole engraving is the same tone. I think I am missing the TTL driver to have toning. Still looking around if I can do something with the ramps D9 output to around 5V to drive the LD. That way I can PWM with M106 S for the toning. Not sure but I hope it can be done.
Can I know if this modified Marlin file still work on a 3D printer? I do not have a laser cutter. I just want to mount a laser diode to work on my 3D printer when I want to do some engraving and switch back to 3D printer when I need to print 3D model. Thanks
