Thanks for your reply MJE
I mainly want to do Vector cutting,and im hoping that my computer will just be reliable enough not to hang.
what do you mean by virtual controller? can i build one easily?
All i said about the 3D cutter is that i have designed a 3D model in Auto cad of the table that i want to build.its going to be a normal table design,i just made up plans for using cheap simple rails,i will share the drawings when i have finished them
