I think I am going to go for the conversion of my RF-31 clone, a Jet JMD -15 round column mill/drill.
I will be using the plans purchased from Jeff Davis at: Learning Home CNC with some modifications to the parts listed on his plans.
I am very interested in the DMM Technology Corp. brushless AC servo's and controls at: Servo products
Mr Li was very helpful on the phone.
with 300W AC servo motor (57DHT04E) Standard NEMA23 - 48V, Max 3000rpm, rated torque: 1.14Nm(160 oz-in), peak torque: 3.0Nm(423 oz-in)
OR
250W AC servo motor (57DML2530L8LK) - 48V, rated 3000rpm, rated torque: 0.8 Nm(114 oz-in), peak torque: 2.38 Nm(340 oz-in)
The complete kit with all wires, power supplies, e switch, limit switches, drivers, 300 watt motors, encoders... Approx. $1100.00
The plans call for Geko's 320's, DC servo motors, and power supplies all sourced from different vendors. Being new to CNC I anticipate a few mistakes in sourcing parts form different places so I feel more comfortable going with a complete package like above.
Keling has a DC setup $1000.00 but the motors are 350 oz

Ball Screws and nuts per the plans from Jeff are approx $230.00
Misc materials I will put at $200 - $300.
Software: MACH3, Autocad, Cam - ??? CamBam, Lazycam or something else.
Opinions and thoughts are welcome
