> I have a use for a CNC plasma and need help. This is all brand new to me. I have the machinery necessary to build the mechanical end but the CNC computer end is beyond my current knowledge. I have very little electronic knowledge. From the research I have done I found this list and I am gathering info daily. I guess the real help is needed right now in figuring out do I need servo motors or stepper motors, ball screws or gear and rack assembly,

These decisions need to be guided by the range of speeds required, the accuracy and need for smooth cuts
on circular or sloping features. The rack is likely to have backlash, anti-backlash ball screws will not. Steppers
may cause undesirable vibrations at certain speeds, while a good servo system should be smooth at all velocities.
If you give us some info on your desired accuracy and required smoothness of edges, we might be more able
to help.
