    great information and ideas I found here.
    For plasma CNC ( stepper motor 1.8° with planetary gearbox 3:1 + micro stepping probably 10x) what you recommend me to use, rack and pinion module 1 or 1.5 ?! And what is the best (ideal) pinion diameter (number of teeth for the pinion ) ?!
    What is the advantage of helical rack ?!
    Appreciate your help!

    Assadi - Plasma is a different machine with different requirements. Anything I could tell you would be just a guess on my part. With that said if I were building one I would use regular straight rack and not helical, or even a good belt drive system. You want speed more than rigidity (to a point). And use good shielded cable on all your wires. There's lots of electrical noise on a plasma machine.

    Helical is quieter, and can carry higher loads.

    Number of teeth depends on the motor and drive, gear reduction, and how fast you want to go.
