And yes guys take it on board I pissed you all off, sorry :-)
Ok that takes guts its a bit like letting the magic smoke out of the drives.

Not sure what you mean by high precision when talking about a plasma. What sort of precision are you looking for.
Steppers are very easy to setup unlike servos and are cheaper and will also provide more than enough precision
for a router or plasma.
How about starting a build log to keep all the questions in one place and start with (if possible) some cad drawings so as the forum can see what you are trying to build.
