I designed a power supply board to make building power supplies easier. The PS board supports 4 axii. It has a screw connector for the transformer inputs to the rectifier, spade terminals to connect to the filter capacitor, a 35 amp 400 volt bridge rectifier, a current surge limiter, a 5W bleeder resistor, a fuse holder and spade connectors for power and ground for each of the 4 axii.

Here is the controller chassis all laid out and the parts mounted. My controller chassis has my PS board, an Antek toroid transformer 23V 400VA to provide power, a 35,000uf 80v filter capacitor, (2) Superior Electric SS2000MD4 drives, and a CandCNC mini-io breakout board. It outputs about 32V dc at around 16amps. Should be enough??

Here is the controller chassis wired up and ready to mount in a case. Now I have to design the case.

For the lathe I only installed two fuse holders and two drives. I plan to use 2 PacSci 253oz. steppers, one to drive the leadscrew, and one to drive the crossfeed.
