Hey Coolantman,
Thanks for that. There are an amazing variety of talents and skills here. Some very bright bunnys and I have been astounded by the abilities displayed.
I hope my CNC will be "up to standard". Its not just a thing you can throw together. I have already decided that the drawer slides are not good enough for what I want and I will build mine with flat steel and aluminium blocked bearings like at
www.cncrouterparts.com .
I am looking at bigger stepper motors too and want to drive them off of a nice home built PSU. (My background in in Electronics...old school analogue mostly, but some digital now......Have to keep learning.)
Thanks for the welcome.
Cheers, Kehla

(BTW its pronounced "keshla" just in case anyone was wondering.)
