G-EDM EVOIII board - Low budget DIY Wire EDM machine

G-EDM EVOIII

The new EVOIII board provides a single PCB containing the pulse stage and the sensing stage. It replaces the EVOII pulseboard and the EVOII sensorboard.

The motionboard is still required:

The EVOII Cube is a cool looking piece of Art but it is hard to manufacture. To reduce build costs and make it easier to produce the EVOIII PCB was designed. Specs and performance of both versions is the same. There is one difference: The EVOIII uses a single gate driver IC while the EVOII cube has a discrete gate driver circuit. At higher frequencies they don't switch identically and the cube needs a slightly higher duty cycle.

The board provides two isolated analog feedbacks and also isolates the PWM to drive the mosfet gates.
