I've been watching Hoss' ZX45 and clocker's Zay7045 CNCing thread with great interest (amongst everything else). Seems like there are tons of x3 threads, but less so on the RF-45 side (which leads to many clarifications vs x3 mods). I'm about to purchase a Machine Tools Warehouse RF-45 clone. In my neck of the woods, it's only $50 more than a super x3 ($1650 CAD for the RF-45 clone). Seems like a no-brainer there.
I'm a research like crazy b4 I buy type of person, but i'm itching to order things right now (especially with some sales going on right now). I'm a complete newbie, hence a lot of questions. Generally, i'm trying to clarify a lot of threads+website links that i've been investigating..
Our electrical guy is coming over tonight to sort out the 220V stuff to see if it's easy to deal with our stuffed electrical board (100+ year old house divided into 3 apts).
1): the base/stand. Hoss' version looks to be 86 inches from floor to max Z-axis extension. MWT says theirs is about 80 inches extended. My basement workshop area is 80 inches max in height. Are there shorter stand heights that i should consider to get some clearance (the stand MWT has is 27.5 inches). I'm not planning to CNC right away, but that's the goal. Will I need the max Z in most cases?
I'll be working mainly on aluminum parts for video+camera mount/support equipment. The largest piece I want to build currently is 5x7x1.5" and may need to be vertically mounted for some parts. Seems like i'll need the extension for this orientation? Will probably be working on steel/iron eventually. Do any of you use 24" or the like?
2) CNCing - if my goal was to go the full 9 yards, ATC, coolants, etc
In regards to Steppers vs Servos, gas struts, counterweights - aside from pricing, are those more of a personal choice here? I'm assuming all the add-ons to the head won't affect the weight too much - any other considerations?
Seems like higher voltage steppers for X+Y in the ~500oz /in and ~1000 oz /in Kelings for the Z-axis, 0.200 in screw threads, Gecko 203 drivers seem to be the general consensus.. any other ideas (I'm open to crazy ones)
3) Tooling - for a vise, what's a a minimum tolerance for precision? and what's a good size for the main vise?
The Glacern Vise looks pretty sweet - any other suggestions around this price range?

or do most of you have wider jaws?
