Re: faster steppers

Henrik, List,

Although the 297/298 chips are ubiquitous(everywhere), the drivers
made with them are NOT ALL the same. This chip set responds well to
good design and layout, and PUNISHES poor layout/design! So,
comparing different mfrs. 297/298 bds is not often apples/apples...

Hope this helps.

P.S. So Henrik, if those ARE 297/298 boards, you must be pretty
good :-)
