Hi, I have a small cnc router that I am currently using, (mostly for drilling purposes), and I am considering building a larger 5'x9' machine to cut plywood and expensive veneered sheetgoods on, mostly on 3/4" material and long 8' cuts. My question is this:for example a nema 23 stepper motor with 269oz./in. What does that mean? What is the relationship between motor size and the workload? Is there a formula to figure out motor size to the load being cut by a cnc? Thank you in advance for your responses.
