Got it. Thanks Jazz.
X and Y are cool. For me now it's just the Z that changes after each tool change.
Have you got an automatic tool change system - Is that another ball game ?
Where would i start with that ?
I am (EDIT:: reasonably) pleased with this, but it took me a whole week to design and make. Hence the 1/2 million lines of gcode and 9 Hrs + machining.
Onto the next idea...
Do you think i could make these out of moulds using the CNC to make a plug?

As you get more experienced you'll be surprsied how much you can fetch Cycle times down. If your doing 3D jobs it's worth Re-tuning your motors biased towards acceleration rather than velocity. It will bring cycle times down considerably.
I was increasing my acceleration and velocity as I went along. Bit at a time.
What i noticed was that the Z axis was the limiting factor, so i increased it, and then obviously my job completed faster, but I felt sorry for my machine. Everything was very warm. Spindle, steppers etc.
Not boiling though, but very warm.
Also I only have one 3mm ball nose bit and i didn't want to break it. I roughed with a 6mm ball 2.5mm stepover, 5mm DOC and then finished with a 3mm ball with a step over of 0.75mm.
Forgetting the design I did, what is the optimum tool size / Stepover for this kind of thing?
Something tells me it's better to design something that allows you to use a bigger tool.

One other thing was that the amount of clean up I had to do was a significant pain in the ass. I wondered if running the spindle faster or slower might reduce that. I tried a range of speeds, but settled on about 15000 as it sounded nice.
PS. Can't sell the wife, she looks after the kids while i'm CNC'ing.

I would like to thank mturneruk, Jazz and eceryone else for the amount of information contained within this entry.
I am at the same position as mturnerUK and just building my control panel and using Jazz's wiring diagram.
Will post images as the build goes on (own thread) but the information has been priceless ;-)
