Smoothie with dual pin (non pwm) supplies

[ghost]

Need to add m3/m5 in LaserWeb's smoothie code too for users with two pin config (pwm into IN via capacitor + TH/TL on a smootie switch pin)

Thanks to TurnkeyTyranny/laser-gcode-exporter-inkscape-plugin#8 for bringing to my attention

Please note that Smoothie config will be need to have a switch to enable M3/M5 to fire. I've got a sample here (pin assignments may need to be adjusted depending on board and wiring)

And, all the two pin PSUs I've seen do PWM on IN. In some cases a logic level shifter is needed because some PSUs don't support Smoothie's 3.3v logic.

(: I have the level converters in my board, and we have it documented nicely on the SmoothK40 Wiki entry too: http://smoothieware.org/blue-box-guide

Thanks for the sample config. Will update the Wiki tonight

This just answered my biggest question on how to wire all this up. Thanks
for the post.
