Hi
I cant say how greatful Iam for your input.
Been posting on cncforum but never got any answers.
I am a sculptor and I been working with 3d and I want to get things
from my computer to the real world, visit my website
www.perpetersson.se
Its comming more 3d there soon...
But for the 4:th axis, I want to make pillars and pillar heads, but
also negative moulds for concrete, wax etc and also moulds for
vacuumforming etc
But also work with colleagues ideas, so no 3-axis limits.
My friend who is helping me with this project recommended me to buy a
used industriel robot 5 6 or 7 axis but I cant afford that.

But to the build: Can the computer run 2 parallel port
simultaneously, and will 2 parallel port be enough for 4 axis?
many thanks
