I have played around a bit with sketch-up. This is what I have so far.. I would like for you all to over look it and add any suggestions. My plan is to design around the equipment I would use on it.
Plans on using
1] 4 pcs Nema 34 stepper motor 1600 oz.in bipolar with single shaft 4 pcs Stepper motor driver DM860A, peak 7.8A, 24-80VDC 4 pcs Power supply 350W 60V 1 pc Breakout board & 1 pc parallel cable. [ will buy from amazon]

2] CNC KIT FROM AMAZON LIST BELOW

1 x RM1605--300mm ballscrew ball nuts + end machined for end support bearings(BK/BF12)
1 x RM1605--1750mm ballscrew ball nuts + end machined for end support bearings(BK/BF12)
2 x RM1605--3000mm ballscrew ball nuts + end machined for end support bearings(BK/BF12)
4 x BF12/BK12
4 x 6.35*10mm coupling
2 x SBR20--300mm liner rail
2 x SBR20--1750mm liner rail

12 x SBR20UU
Note: The ballscrew kit is C7 standard with standard machine end.
All the length of the ballscrew and liner rails kit can be cut at any length.

I have not pick the spindle yet, to design around it. So any design ideas you fellas have would be nice to hear them. Also I would like to know what other electronics I would need, so I can budget my spending and source them while I do the rest of the build. I was thinking about appox $3000 to $4000 U.S.
