Hi,

Thanks for the info. I am thinking 3 to 1 on X and Y and 2 to 1 on Z as my Spindle will be large about 15 kg. I see they offer grub screw and key cutting service as well so will have key cutting on the servo side and grub screws on the ballscrew.
I understand from your info given ( 20:30) that you calculate the gearing ratio by the tooth count?

I see you are using on your new machine the west systems 105+209 wich I know is ideal for this application the only problem beeing that here in the uk the weather isn't ideal :) Do you think I will be ok with the 105+207 or 206?

Thanks again,
Vass
