I am a bit confused about those motors... is there a way to calculate how much torque I need per axis? I tried posting a question about wich motor to chose under the sticky thread "What stepper motor should I use" but havent got any replies.
I am also considering using steel for the mainframe since it is cheaper and more sturdy (but can also rust...), but use aluminium for all the moving parts...
I really woud like some help with those motors though... I have tried to read around the forum, but I cant seem to find what I am looking for. I see those cnc made from wood use around 200 oz. in., but since my is gonna be made of aluminium it is going to be heavier... |
