Jon,

I'm confused ( no surprise there ;-) ). Does your board simply output
independent channels of step pulses, possibly with trapezoidal accel/decel?
If so how does it handle curved paths? Hopefully I'm missing something here.

On a slightly larger topic, what must such a device be capable of doing to
handle the capabilities of G-codes? Is it limited to linear and arc
profiles? That's all I'm seeing in the G-codes (granted helixes are just a
third axis in synchronized linear motion).

Thanks a bunch,
