The machine was wired at the factory for 460 volt 3 phase and we use 230 volt 3 phase in our shop. Ed and Dean rewired the motor and controller box, in a temporary fashion, to use 230v. It had been using a 460 to 230 volt transformer. Ryan removed this 6/26/2015 and changed all three transformers to use 230V, and re-enabled the accessory outlets at the rear of the machine. He also moved the Heidenhain power source back to the Bridgeport control. PS:One has voltage approaching 250V, so in some cases the voltages at transformer taps are a bit high. However the Heidenhain power, and the external 120V outlets, appear pretty much spot on. | The machine was wired at the factory for 460 volt 3 phase and we use 230 volt 3 phase in our shop.
