Im just about to do an upgrade on my CNC Lathe to a more expensive Centroid system.

I'll have my setup for sale if you are interested.

Its a Pokeys 57U board + Expansion board. It runs off USB, so need for serial etc, let me know if interested.

If you have an existing parallel port etc, you can just get a cheap BOB on ebay for under £10. Do you have any pics of the bit that has failed?
