Some of us already HAVE machines w/ high speed travels;)  Hossmachine
claims his X3 sized mill does 300ipm (and others videos report similar) =
127mm/s.

What are the acceleration rates on the dedicated machines?  That might be
more of a factor w/ the back and forth fill that the slicers appear to
generate.  The dedicated machines will prob have the advantage there.

Live Security Virtual Conference
Exclusive live event will cover all the ways today's security and 
threat landscape has changed and how IT managers can respond. Discussions 
will include endpoint security, mobile security and the latest in malware
