Hi guys, i have been messing around for the past few months with a idea in my head to a design i made up as i went along
acquiring bits and pieces from eBay.
I originally thought that thing would work out cheaper if i had made allot of the components myself and it was, however i was
lumbered with more work than i hoped for.
x axis 35mm linear beating 1.2 meters in length with 425 0z nema  4:1 timing belt and gear set @ 5mm per rev ballscrew
y axis 30mm linear bearing  860mm in length with 425 0z nema 23, 1:1 @ 5mm per rev ballscrew
z axis 25mm linear bearings 200mm in length with 425 oz nema 23 on top 1:1 @ 2mm per rev ballscrew
a Axis 6 inch vertex rotary table 90:1 ratio with a futher reduction gear and belt of 2:1 giving me 2 deg per rev from a 425 oz nema 23
power supply home made tordial 35volts @12 amps
drivers bipolar microstepping 50 volts @ up to 4.2 amps per phase
table frame made from 50mm square tube tig welded together and the rest from aluminium off cuts found laying around.
PC is a bitsa i put together out of parts i had floating around p4 2gig 512ram.
I have yet to wire it all up and get it going with the mach 3 software that i recently purchased.
So far it has been an interesting exercise, and i can see where i made mistakes and avoid those same mistakes on the next machine i build.
It could have turned out a hell of allot better if i had all my bits together and planned everything before i started, but hey you live and learn

Looks like it has lots of potential.  Looking forward to seeing some parts cut with it!

Looks nice ............................................. and clean. Good job.

Thanks guys, now its time to get my head around the mach softare before i even think about cutting any parts.

cheers
