It's unfortunate that there isn't a way to approximate closed loop control with
steppers and encoders in EMC2. I have read that EMC2 can detect a following
error using steppers with encoders and trigger a fault which is great but this
doesn't really allow the use of steppers in larger or high

On the other hand you can do a lot with a embedded 32 bit processor in a

is BSD licensed and has a GCC toolchain)
Which again, sounds like a plus till you said 100mhz. That might do for
