Not perfect but I think I have got it down pretty well.

I don't have a 3D probe yet so whenever I reset the machine I am obvious out somewhat.
The last operation of cutting out the case was well out for some reason..





I am working now on setting up a spoil board underneath the stock to then super glue my stock to.
This means I am not cutting out something floating in mid air.

Just another bit of aluminum stock will do that I can then glue my work stock onto with super glue?
