So i have a Rapier 2 rotary machine gifted to me to start practicing. I havent done anything on real skin just the fake silicon skins. I run my machine at 8 volts for the lining. works out pretty decent. can get clean steady lines with it. But i have absolutely no idea what cps it is running at. Does anyone know this? tried to contact the builder but did not succeed. Tried some shading with it running it a ~ 5 volts. Not so good it went way to dark to quick maybe its just the greywash is to dark maybe the voltage is to high not sure. How can i figure this out except lightening the greywash wich i will try now.
