I think that's just a demo of there super fast pick and place machines, if you really want to see into the future of CNC then watch this video, No ball screws or bearing rails. Just don't know how you'd measure gantry displacement under a cutting load ?

What bit?

Pick up head will be vacuum, and it looks like some form of belt positioning for the axes.

tyhats all great, but the festo thing 'for the hobby bloke' simply has belts but no y axis motor [on the y axis]

the y axis motor is static 'like the x axis motor, but some how it works i dont know how!!!

some one draw me a diagram

i mean ideal layout for a plasma table if yuou ask me

i only ask as I just had a little festo linear combined must ne ball screw thing and I looked them up.

Post some pics or search https://www.google.co.uk/search?q=festo+linear+combined&tbm=isch&tbo=u&source=univ&sa=X&ei=3zptU8vqF-Ts0gXf04DoAQ&ved=0CFAQsAQ&biw=1564&bih=887 for one that looks like the one you've got. then someone maybe able to help you.

yes i have seen that

but have YOU seen their robotic bird?

hello, I simply bought on ebay one of these
http://img.photobucket.com/albums/v222/pantswagen/festo_zps9a42f8f2.jpg

to use as a y axis for a small 500 by 600mm plasma table, the end on it use aleen bolts that then are threaded to m3 I think tso I can simply recess the shape of the end into my gantry ends and bolt through = simple!!

1. plasma torch height simple electro magnet and spring up down in the torch holder
2. bolt the crash magnet straight to that mount and stick the torch holder to that.
y gantry ends 10mm aluminium with the motor like a trad machine.
have 45mm box lengths for the x axis - light and simple, don't know how to drive and bearing them though, 'typically' sold a pair of thk 32mm rails and slides = oops
------------------------------------------
------

then looked the stuff that they do up on the internet as this companys stuff is simply awesome!!

that then led me to that H set up, which I beleive has one continuous belt running around the 'H'

what is foxing me though is I doubt it could be controlled with sheetcam and mach3, as both motors would need to run in different directions for up and down on the 'x' axis

THEN in order for the y axis to move, one motor works and the other free wheels????

how it works when they both move foxes me

all I know is I need a light weight table that I can store easily

p-80 machine plasma torch? non scratch start, pilot-arc, £40 or a blow back? but they aren't cheap.
try a hydrovane compressor = no wetness or noise. 7 cfm

oh and a 'bed - o - nails as the bed, but nuts and bolts instead simply m6 by 50mm pan head posi's into a 8mm tapped alloy surface bent up at all sides so as can be a tank for water, that the cnc simply snaps into

anyways that was the plan till i see that H gantry doofer!!!
