How to achieve a “4th” axis on a regular 3axis router CNC - just came over this video showing the technique and dont recall seeing it here on the forum:
That is cool! Nice find
at first I thought that wouldn’t stand up to large forces but upon closer inspection it seems very well engineered.
Very cool idea!
Aside from just a simple cylindrical shape, I can’t even begin to comprehend how you would design something with this method.
