I cannot envision having to scratch engrave anything more complicated than a dollar bill - how do I work backwards from the result to determine the type of motor and ballscrew I would need?
Is there a recognized calculation, or is this gut feeling?
range of applications - cutting PVC's .125 - .5", acrylics .125-.25, scratch engraving light metals, soft & hard wood milling up to 1".
Hoping to cutout aluminum, brass and other soft metals unless this bumps me up into the next bracket.
I am not looking for high speed - my intent is to have several machines dedicated to specific tasks.
