The first custom machine running on G-RBL starts to produce some very stable burns.

It wasn't easy to get it running and the code had many changes that will be part of the next release. I'm impressed with this build.

It uses a TB6600 driver ( don't use them! Don't look at them! Maybe pretend those things don't exist at all! ) the step resolution is 346 steps per mm. So it is hard to get a stable burn at all as a single step can be enough to go from the lower setpoint range to a short circuit.

The pulse circuit is a little different from what is used in the G-EDM. It is currently a power resistor based circuit and the feedback signal doesn't measure the voltage drop on the PSU but the spark gab voltage.

It even uses high precision cutter-mud as dielectric.
