Re: Direction follower ?

Dave:

I can almost picture the cutter on a swivel like a ball castor on a
chair.
You would have to figure out how to compensate the tool path, because
the cutting position is offset from the tool holder position.

Then also, If your cutting stain glass, the parts need not be super
accurate and the cutter/holder offset can be very small and track
good enough.

The only alternative I see is to mount the cutting wheel directly
under a rotatable tool holder and rotate the tool holder in the
direction your moving.

However you do it, you may find yourself writing your own controler
code.
