-its ugly the motors to be at the front, put them at the back
-> Yes I correct that on the latest design I put the motor on the back

-100x100x3 is well enough for the base
-> really, I could be a more economic choice and easier with my 160A TIG. But in this post Dean recommend 6mm tick on simular structure ?

-invert that motor on the Z so it's not so ugly sticking up, also all would look more compact
-> Look at the latest design #6, I done like you suggest

-This machine looks much like my first build combined with Deans Gantry design, so you can check how i made the z and maybe all the build log, furthermore i have the plans in sketchup for free
-> Thank you, I also read and probably be inspired by you design also... Can you send me you plan in private message ? I try do download it by the link don't work or I don't find it ... I am not certain

-invest in a proper straight edge and save on that epoxy, by just shimming the rails. Long ago when was making mine 1st build, i was insisting on the epoxy and wondering why Dean shims the rails, now i know, 200e in my pocket. i would buy calibrated steel bar say 40x6mm and epoxy that precisely to the frame and mount rails on top of ut
-> Finally I change and go on aluminium bed with 160x80 X. It is cheaper and simpler than steel plus epoxy.

-check the Youtube video of that one i am talking about https://www.youtube.com/watch?v=C9hT...ature=youtu.be
-> Yes I already view it, I will look at again

-for a serious Z axis you would like to move the rails not the bearing carriages, furthermore overhang should be as minimal as possible and that a key in for a perfect finish on metal.
-> Could you develop, I write than both mount have their own pros/cons but don't remember that it have impact on finish.

-servos are 10x upgrade over steppers IMO, go for it, 2:3 is the correct ratio for such machine, 400w 230VAC
-> have you recommandation on model and provider ? Dean advice to go on closed loop for the ease of wiring, setup and reliability, I am interested to have different opinions !

Thank you for you help
