LinuxCNC configuration for a $100 chinese "laser engraver" using 7i92 ethernet motion control. I nickname it "rosh" because it came with what was looks like a regulatory compliance sticker that says it is "ROSH" (not ROHS).
As shipped, it has a microcontroller (arduino pro mini knock-off) with GRBL pre-loaded. Right now, my setup consists of point-to-point wiring to the microcontroller daughterboard to use the supplied stepper and laser drivers. It bypasses the microcontroller by tying its reset pin to GND. Later I hope to desolder the microcontroller board and replace it with a DB25 adapter.
I'm creating raster images using a little bit of custom software,
Contrary to the name, it can accept any image type known to the Python Imaging
While the software was written to support PWM laser control, I have found that this doesn't give good results on wood. The result just is converted from a 1bpp dithered image and rastered at 450mm/min at a size of about 1" x 2/3".
