What's it for Rod ?

It's for controlling amongst other things a rotary table and supersedes the use of something like this:
http://www.ebay.co.uk/itm/like/37041366 ... =83&ff19=0
The controller operates the stepper motor which can be connected to the lathe spindle or rotary table.
So if I'm cutting a clock wheel with 100 gears say (100 divisions) the controller when "dialled in" will rotate 1/100th at a time.
This is a well known made up version:

This set-up can cost up to £300 just for the controller - my version using some of Steve's ready made boards works out much cheaper - less than £100.

Hi Rod,
A mate and I are making the exact same thing. We have gone for the mebrane keypads and making our own boxes. If you are interested I take a pick (I don't want to try and hijack you post).
Please keep us up to date on progress

Yes please James.
Good idea to make your own boxes, the Farnell ones are one of the more expensive bits of kit at £24!
The Motor Driver is on it's way from HK only £10.
My friend has the Division Master and it's a nice bit of kit - saves a lot of hassle.
Hope this works as well - they are supposed to?

Hi Rod, which motor driver are you going with?
We have chosen to stick in the UK and will be buying from here http://www.diycnc.co.uk/index.html.
I will get a quick picture of our progress tommorow evening.

The motor driver was based on the Stk672-080.
Caused me some grief as I was trying to wire it up bipolar but this will only work unipolar!
Here it is test wired up - will have to replace the 4pin XLRs with 6pin ones.
Will also need some more heat sinks and perhaps a fan but the case is rather small
