How to change output voltage to 5v
« on: February 23, 2017, 07:59:18 PM »
First what with all the negativity these days, I want to say that over the last 9 years I have been using my G100 for hundreds of hours and still don't understand why the various parties gave up on it.  I run Mach3 on XP on Bootcamp on a Mac PowerBoook.  I run 2000 line (4000 quadrature) encoders on 1/3hp dc motors.  Not sure if anything today comes close to some of the specs of the G100.

Now to my question.  I'm trying to make this G100 brained Shoptask Mill/Lathe also able to 3D print.  To that end I need the 16 digital output pins to be 5V max instead of ~9V.  The specs and schematic indicate the outputs can be 5-24V.  Unfortunately, I can't figure out how to change this.

Any ideas?
