Some design questions

[cropwell]

I hear what you say Eddy, and I might go that way, just take off the motors and spindle mount and sell the frame. I don't actually use the T slot bed, there's always a sacrificial MDF board.
I want to keep the controller box I made.

I am probably going to have a twin screw long axis and would need to buy a stepper and driver. I have got 4 Astrosyn MY103H702 steppers sitting in a box (bought for a project which never happened - cos I bought the MD machine). These are smaller than the 57BGYH7630's on the MD machine, but two of them should be OK on the one axis, but it might be as easy to get another 57BGYH7630.

The driver is a Tonman PD2064M and I will need one to drive the slave motor - anybody know a supplier that is not in Exeter ?

If you're going to eBay it, sell it as a complete working system and you'll get a lot more for it. CNC Routers seem to go for over the odds on eBay at the moment, regardless of the build quality...
