Hi all,
I'm currently building my first cnc machine. I've absolutely no experience (of cnc - my job is PLC controlled automation).
It all started because my best mate bought me an Arduino for Christmas.
Funnily enough, I'm not going to use the Arduino in the main build - I'm running it from an old PC running LinuxCNC via a parallel port to a break-out board.
Anyways... I started thinking about what I could use the Arduino for and wondered if there would be a benefit to having a variable speed spindle?
I could control the Arduino from a pot on a control panel to alter the speed of the spindle?
I'll mainly be cutting wood (maybe a bit of engraving on aluminium?).
Any benefit to this or would it be a waste of the Arduino?
Thanks :-)
