Hi Larry:
I dont think there is a way as yet other than the GCode, or the arduino method. The problem is that GCode can provide triggers, but the arduino provides actual
power levels. Both the Mach's can handle binary laser control, but the arduino with Darwin is the only way to get instant power level switching and triggering only once per
step. This will eventually change when here is some agreed upon standard for a protocol, but in its absence I siimply went with what worked well. Im probably the only one
using it , but it does work well. I know theres at least 1 or two others using it really, but I know too its not easy for people to make such things.
Its probably be easier if there was just a protocol for a pwm power level which is specific to each trigger.. Im sure it'll come eventually, my arduino fix is just a holder till
M4 can handle a downstream pwm from image command. The arduino can change power on each pixel of the image, to do that in Gcode the code woudl be truly huge..
I mean 10's of millions of lines probably.. where the arduino equivalent is quite small, just a fast raster pass with power all taken care of.
