I seem to recall the cutter rotates about the vertical axis - and if the wheel is small enough maybe no lead in/out required?
Neat project - what do you plan on cutting/making?

about 1/2 way down a good shot of the mount for the cutter - its directly mounted to a stepper! (well it sure looks like it anyway). That should take care of lead in/out - the blade would always be tangent to cutting line - an interesting 4th axis to solve! -- Jim
Experience is the BEST Teacher. Is that why it usually arrives in a shower of sparks, flash of light, loud bang, a cloud of smoke, AND -- a BILL to pay? You usually get it -- just after you need it.
