Hi Peter,

I don't know if this will help, but there is a home built CNC controller box being sold currently on this forum which includes a UC300-USB as well as stepper drives, PSUs and so on. Might be worth a look as an instant source? Have a look at http://www.mycncuk.com/threads/11465...8299#post98299.

Hope that helps!

Cheers
Graeme
