I am starting to crawl

[kool-lites]

Hey guy I am new here and will be starting a CNC Mill soon.
I trained as a Elect Eng but love mechanical challenges.
My goal is to build a routing mill that will make PCBs.

I have heaps of questions. Like are the Controllers on Ebay that use the Toshiba TB6560AHQ chip worth while?

how do I spec my PC? is a Compaq SFF 1800Mh P4 with 2G ram OK? it is probably one of the only one I own that has a Parallel port.

I stumbled across Small Parts & Bearings. is this the only supplier of Pulleys Belts in AU?

Cheers & Thanks
Matt

SPB is the only one I have seen. You could use a Smooth Stepper via USB http://homanndesigns.com/store/index...ain_page=index Breakout boards etc here

your pc will be great.
those toshiba chips are good value, i think ebay has 3.5 amp 4 axis cards which can take 50v. (i think thats right?)
most smaller nema 34 motors will party with that.
but, cheap drives all suffer mid band resonance, if you know a cheap way to fix that let me know.
