finally getting on with this.

Going for a rig thats 2000mm double x 1200mm y 300mm z

ordered this lot

supported linear rails SBR20-300/1200/2000mm rails(6 supported rails+12 SBR20UU bearing blocks)
4pcs of ballscrews RM1605-350/1200/2000/2000mm overall length-C7(4screws+4ballnuts+4end-machinings)
4 SETS OF BK/BF12(with locknuts and cir-cplis)
4pcs of flexible couplings 6.35mm*8mm

am building a base similar to the above mentioned thread, with a few modds for rigid bed

am going for duel x motors, so heres my first question.

There now seems to be nema23 and nema24 motors, with the latter having more power eg
4 Axis Nema24 Stepper Motor 567oz-in CNC Controller Kit With Display And Keypad | eBay

so, is it worth the extra for the nema 24s, or is there something am not seeing ?

I want the Y gantry to be heave duty so i can maybe strap a B/C head on,

question 2 would a nema24 be overkill for a y axis at 1200mm travel, would i be better of with nema23

Question 3, i want to build a heavy duty rotary table on part of the bed, for stone carving. would nema 34 cause me any problems with lighter weight things like wood or foam and what gearing would you recommend.

i sort of need to order the motors over the next 2 days
