    I've only got the parts list for the stepper version, and it uses 12:30. Chaz has a servo version, but I don't think there would be much room to go for a higher ratio.

    What size timing pulleys would you suggest for 200 or 400 watt servos? I was thinking that 5M 9mm wide belt should be about right. Centres should be around 100mm.

    I'd say 15mm belt width minimum.

    If you download the Gates DF software, it will generate suitable drive options.

    Hi guys, I'm going to build a machine to drill and tapping one part, I'm thinking use a servo for tapping and a regular spindle for drilling. Using a regular servo I can do rigid M3 tapping on 2mm aluminium sheet? Have anyone experience with something similar? Tks

    To do rigid tapping you will need a quadrature encoder on the servo and some thing like Linuxcnc to control it.

    Here is a link in Portugal where you can buy the Mesa cards 6i25 with 7i77 bob will do it.

    Are you think of having the spindle and servo on the same gantry?

    You can also do rigid tapping with UCCNC, and with Mach3/4 with the right motion controller.

    Yes, spindle and servo on same gantry.. Ok, I have a lot of questions but i will study quadrature encoder and servo first, and do stupid questions later.. Thank you for the help.
