Hello,
Iam building my new cnc machine, In this moment i have a JGRO Type cnc machine, powered with 4 axis Hobby CNCPRO controller card and 305 oz/in unipolar stepper motors.
I want to build a 4th axis, My idea is use the reduction with timing belt, and two pulleys.
My stepper had ¼” shaft, I think to conect a little pulley of about ¾” external diameter and ¼ bore
.
The big pulley I think that can be a 3” or 4” inches diameter. For the bore I don’ have Idea.
Distance betwen pulleys aproximately 8-9 inches.
I don’t have idea about number of teeht in pulleys, timing belts, etc.
May somebody help me? Please sugesting me kind of pulleys and timing belt and in your opinion best suppliers?
Thanks in advance
Rene
