Arduino Due Mach 3 Laser
Here a simulation from the software in the Arduino Due I use to control the laser.
with the input "mode", I connect it to an output from my breakout board, and I make a button in my Mach 3 screen, to control this output. so with a button, I can make this output low/high, and so I can choose the mode on the screen. In on/off mode, the input on/off controls the laser from 0 to 254 ( 0 to 100%)... in the other mode, I use 2 outputs, like a stepper motor... One Dir and one step input... and then u can use the laser output like up/down your z-axis... do you understand this?
