Hello all,
I know there is a huge amount of knowldege within the minds of the members on this forum so I thought I would ask for some input. The owner has decided that he wants to build/have built (the frame with us/me doing the controls) a CNC Router for cutting plastic. We have a small tool room with a mill and lathe but we have been sourcing out alot of cutting work. The CNC will be large enough to cut 4x8 sheets with a normal thickness of 1/2". There are a large number of sites for homebuilt CNC Routers online. But, I have been unable to find much on Stepper/Servo setups. I know servos tend to cost more and the decision on which to use depends on speed,accuracy and load. How do you calculate the load, how many in-lbs would be needed? I know with most things you get what you pay for, but there is a huge differenc in price from one brand to another....where is a good starting point.
Thanks,
Micheal
