Belt or Rack
 

Hello everyone

I am in the process of manufacture of my machine and I have a question about what kind of system I use for Transmit motion, the general specifications of my machine would be:

axis x 183 cm
axis and 244 cm
z-axis 30 cm

I already have the engines MotionKing ref 23H8603, the idea is to make the transmittance of motion directly, but because of the cost it would involve using the rack and pinion system intended to use timing belt and pulley.

Do not know if this is the better or for this size of machine is only recommended the use of rack and pinion.

If i can use pulley and timing belt which would be the appropriate size?

Thanks

Gustavo,

your engines look awefully small for the mechmate, what made you decide to buy these small engines?

The Mechmate is designed around rack+ pinion with a nema 34 size engine
With your type of motor you need to use a timing belt, 1:3.6 is a favorite here,
