Hi Guys,
I finished building my first cnc router (dremel) measures a 24" x48". The whole machine is made of Aspen wood. I'm using 425 oz stepper motors with 1/2 10 2 starts acme leadsrews. My x-axis is 48 inchs long and would like to put a timing pulley belt system on it for more efficiency. The gantry is 32 inches wide, there is some mass there. I've looked at timing belt pulleys, and not really certain what to use. Any suggestions would be appreciated.
