Hello I am a Tool&Die Maker by trade, evolved to C.N.C. Cutter Path Developer. Going to be retiring soon and I want to build my first robot. Would like to know about programmable software. It would make my world simple :-) to find something that uses X axis Y axis grid design using a common start point referencing to a X 0.00 , Y 0.00, same as what you would find on C.N.C. machines . Since I will soon be retired I will need to keep the cost low. Any advice you can give would be greatly appreciated.
