Hello,
I'm building CNC plasma and i need a gear reduction ratio 3:1, for my nema 23 stepper motor 3Nm, my drive system is rack and pinion Mod 1. I have difficulty choosing between:
- planetary gearbox PLF60 from china
- or just using belt reduction based on 2 pulleys (GT-3MR) 20:60 tooth and gates power grip belt 3MGT width 9mm !!!?
What is better ?! Does anyone have experience with the Chinese planetary gear ?!
