I have been a long-time lurker, and will be pulling the trigger on a ZX45 sometime next week (i already have a non-CNC-G0602 and figure i should have a mill too . At the same time, I intend to buy all of the stuff to do the CNCing, and was hoping to get some feedback on my parts list. I have been scouring this forum for a couple of months and have a spreadsheet of other's builds and the parts they used. I am sure I am missing some stuff, but they are unknown unknowns.

Automation Technology 3Axis 1125oz Servo Kit
3 ballscrews 2005-750/940/1100mm endmachined + 6 nuts
UPDATE: Some Type of Enclosure (not a computer case)
Timing Pulleys from sdp-si.com (not sure of the size)
Belleville Washers (from McMaster (part number?) - 140lbXY 180lbZ, 5 each axis)
Timing Belts from sdp-si.com (not sure of size)
Limit Switches

If the AutomationTechnologiesInc kit is undesireable, I will go with these:

Automation Technology KL34-180-90 1125oz
Gecko G320X Drivers
Digikey encoders 102-1307-ND
CNC4PC C11T breakout board
70VDC 1000W Antek Power Supply
