The basics
Will_D:
Thanks, it seems there is a lot to learn still.
Its not just about engineering the mechanicals is it?
PK:
A machine controller is a fairly simple thing. You can expect.some minor frustrations as you learn how it does.things. Hobby level Geode is so simple you can almost ignore it's existence. Most of the grief comes from electrical noise and idiosyncratic software.
Joules:
Will, start out with something really basic like a desktop router. Forget limit and home switches, play with belt and lead screw designs. You can try out different arrangements based around the same basic frame, add bells and whistles as you like. Get a grip on the software side, see how much force your drive can produce (luggage scales) then move onto a mill or lathe as the fancy takes you. Even start with just one axis !!! Most of all, have fun playing.

Funny, it's the mechanicals that usually turn around and bite me - not the electronics and software. I blame myself for this though, as my shop space and access limitations give me a legitimate excuse to avoid quality (big and heavy) equipment.
Wanna team up? :P
John Stevenson:
Good advise from Joules. Convert a dividing head or rotary table into a 4th axis.
At least this way you will still have something of use.
I never fit limit switches to my machines or homing. Homing wastes far too much time. just set work co-ordinates and machine co-ordinates to the same point and then zero on the corner of the work or vise and you always know where you are.
OK for the big boys who use the bottom paddock as a bed [ you listing Mawson ? ] and use G53, G54, G55 etc to machine 10 of the same item at one setting.
Us mere mortals are had pressed to get a fag packet central on the bed and under the cutter.
