I am building my first machine. I Am a team leader for a cnc laser cutting department, so I am familier with cnc just not the building of the machines.
I am building my machine based off of the plans at http://www.scribd.com/doc/2999440/cn...-plan-cnc-plan Difference is I am using a mixture of 3 mil and 4 mil instead of Wood. I have my eye on a set of used steppers the stats are.
Superior Electric Slo-Syn stepper motors:
NEMA 34
Model# M092-FF-206
370 oz-in
4.0V
4.0A
4 wire
by the time the gantry is finished I figure it will weigh about 30 to 40 pounds. I will be cutting 4mil mild steel. Speed doesnt really matter at this point but price does. They are ASKING $180.00 for three of them. there used. My question is are these over kill can I get away with some thing less powerfull and therfore cheaper? Or are even these ones not big enough?
Ill post pictures as soon as I find my camera.
