I am a crazy hobbyist attempting to build a cheap and precise machine in my house.
precise enough to cut parts for plexiglas enclosures at least
I want to use rack and pinion drive, where the motor would drive the pinion directly over the rack.
Can you check my math please:
I am really not sure how I know the carriage acceleration. My machine will move the dremel tool over the material most probably.
Thank you.
