Re: [CAD_CAM_EDM_DRO] Bridgeport series I to servo motors

I did exactly what you are contemplating. Have been using it daily for the last 17 months with excellent results. Look for brush-type Nema 42 DC servos in the 100volt/15 amp range (not stall current) on Ebay or elsewhere. Usually rated V/Krpm, so a 40 volt/k rpm motor with a 2500 rpm would be a 100 volt servo. Gecko 320's will control large servos at lesser voltage sacrificing a bit of speed and not any torque providing you have the neccessary amperage from the power supply. 15 amps is probably plenty from the power supply for all 3 axis.

A 1 Ghz or better PC running Mach2 with Bob Campbells breakout board(interface between PC and Geckos). Check mine out at Yahoo groups CNC-pics under rogersmach. It's a very easy retrofit.

What is the best electronic hardware to convert Bridgeport series I
to brush servo motors? Would it be geckos and what do they plug
into? Which power supplies are best choice for about 20 amps? Three
axis is required but may wish to add a fourth later. Who are the
best suppliers?
