General Mach Discussion / 3d Keyfobs

« on: December 10, 2010, 10:11:03 AM »

I am very new to this and have only had my machines a short while but I have been asked if I can make keyfobs with pictures in 3d on them  kids pets etc.
I am not sure where or how to start. I have solidworks and solid cam and a denford starmill. the fobs only want to be about 50x40mm and a base of around2-3mm.
Is it possible to do this and where would one start with this project would I need other software?

Please help if you can as I have a few people who would like stuff doing for christmas and the wife keeps dropping me in it by saying of course he can lol.

Iam reading the manual I am strugling a little to get my head round it.  I know this bit of code ref to offsets etc in the machine we are using but my main question is sort of I know
the program we use at college is alphacam and this outputs the code to the machine we use there.What do I need to do to get the code to output to a format that mach3 understands?
Or am I comming at this from thw wrong way, please tell me if I am being dumb on this I jst have not got my head round how things go, Hood did a bit of code for me and I was very greatfull for the pointers I get that I dont need the line numbers I think but the rest at the moment is I think over my head or I am just slooooow at this lol
