Just to completely address your point, there SHOULD be some open-source
hardware accessories
for EMC2. Samco has an open-source

But, I think the difficulty of making your own boards for FPGAs, and
then building them and
testing them may have made this too complicated for the average
tinkerer. Without a logic analyzer
and an oscilloscope, if it doesn't work, it could be real hard to

That's not nice!
I know that developing take time...

If you have enougth money to buy $7000 machine then there is stupid

Actually, the EPP is a real MESS! The spec is very poorly defined, and

Hello
I'm use EMC with 25uS base period. This came little coarse now as I get
stronger motors for my machine. So I look under the hood of emc how

Interesting.. But that line in docu seems taht something is strange here...
the stepgen outputs one complete Gray cycle (00 - 01 - 11 - 10 - 00)
for each step it takes.
I suspect a documentation error.
