So to start off

the Stepper Motor . - what would one suggest .. Servo or steeper -
what kinda Stepper size would i need.
the price diffrent of NEMA 23 seen much cheaper .. would it be enough for my task ..?
------------------
IF NEMA 23 is the choice . what Oz would be better . 270oz or 425oz ? the price different is not much .

----------------------
WHat is a Breakout Board . -????
-----------------
Can i use USB .. or upgarde in future if i need too .

---------------------------


I am also having problem to find a LEad screw for my cutting size --
can someone point be a direction ?
-------------------------------
more or less i should have no problem making the TAble for cutting .
but the technial aspect on the steeper and computer is a kinda confusing for me .
--------------------
what would be a good software to use - i am good at illustrator on adobe , but not sure if . 3d is the same ..
------------------
if you have package which you think is good or better please kindly suggest and put your reason why .
-----------------

well i am looking at about 300-500 usd for the 3 axis package . to start off .
and kelinginc seem to be offering alot of parts .
--------------------

Spindle
------
base on cutting MDF that is 20-30mm thick .
what would be a stable good spindle - hope to keep price below $200
with lot of option to upgrade or after market parts . some spindle might be good but the drill bits and parts is expensive - i am guessing .
do suggestion . what is good .or what is best for my project .
------

i am so new to al this please advice , suggestion correct me if am wrong in anyway .

I think you might be out of the hobby league trying to build a machine as durable as you're requirements. 6-10 hours a day is going to require a very robust machine. And MDF is a horrible material to route because the dust clogs up everything.

I would suggest you look for some good used routers or even a new one. Komo, Thermwood, Gerber, all make wood routers. It sounds like you'll be in a production environment so get yourself a production machine, it will pay off in the long run. Also make sure to get an automatic lubrication system.

If you're just starting out a new business you might want to save your money and until you can afford a production machine send your parts to a local cabinet shop.

Good luck.
