There's the rub - seems EMC is good with servos. Everybody who says
there is no problem with CV in EMC is using servos. It's crap with
steppers compared to Mach.

I've posted code, videos and files highlighting the problems and there
has still been a total lack of response from the guys on the committee,
I mean total lack!! - I've been on IRC, posted in the group, asked nice,
insulted them - f**k all response. I'm still of the opinion that if it
doesn't affect one of them personally - they don't give a shit.

Last time I voted for one particular person who was vociferous in the
emc group. Soon as he got in - silence... You know who you are
spadnos...

Talking about voting - isn't it well past the next election, or has it
just become a dictatorship?
