I’m now in a position to actually start the CNC conversion of my milling machine.

CNC4PC site has a  LOT of great stuff to get. Between it and the Keling site, I should be able to get all that I need for the conversion.

What I should need:

3 x KL-5042 or KL-6050 : $41 ea
3 x KL23H2100-50-4B : $55 ea
1 x KL-350-48 : $50

Total = $338

And From CNC4PC

C35 Breakout board : $39
Limit Switches : Mechanical or Optical : $78
E-Stop button : $10
3 x Ethernet to Keling driver adapter : $4 ea

Still need: cable for power from controller to motors.
Also posted a question on CNCZone.com to see if I’m missing anything critical to my parts list.

So far by my calculations, the total is US$569
