# linuxcnc-rosh-laser
|
|
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, `pgmlaser.py`.
|
|
Contrary to the name, it can accept any image type known to the Python Imaging
|
|
Library.
|
|
|
|
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".
