Hi Silyavski,

I see you have used HTD pulleys and belts on your machine. Did you get those from Zapp?
Also I see they do key cutting which makes it easy to mount the pulley to the servo but how did you mount the pulleys on to the ballscrew. I know its a newbie question but that is what I am. I am thinking to use 3 to 1 reduction and trying to figure it out. Also do you need any special machining for the ballscrews when using pulleys? HTD belts are a good option for me as they are rated to -25 Celsius.

Thanks,
Vass
