Gecko 201 & Gecko 210

Hello!

This is my first post. I am also new to the step drivers, CNC
software, milling machine (ordered an Eldorado milling machine)
etc. I am researching on stepper drives. What is the difference
between the Gecko 201 and 210 steppers? I went to their website to
find any answers, but no luck. I know that the 201 has the
microstep abilities, but the 210 doesnt say it has microstep,
but "acts" like one. Could anyone have an answer between the two?
Thanks for any feedbacks.

Sincerely yours,
Mac
