I have been reading the information and guides on this site to help me clime the steep learning curve of CNC conversion. I have a Amadeal AMD25LV mill that I wish to convert to CNC on 3 axis the M/c will mainly be used for making clock parts in brass and some light steel machining. Using the very good tutorial and spreadsheet by irving2008 I have calculated I need 3.1nm stepper drives for the x and y for the vertical Z axis I am considering using again a 3.1 stepper with a 2:1 timing belt to give more torque and also position the drive out of the way of any counter balance that I may need to fit, I plan to use the original lead screws but change the nuts to control backlash.

Firstly does the above sound sensible?
Secondly I have seen stepper motor and drive kits at CNC4YOU at what looks a good price! are they a good buy?, if not can someone recommend a good motor/control combination.

Lastly all my computers run on Ubuntu which is a Linux operating system so naturally I am looking at LinuxCNC, any comments please.

Thanks in anticipation

Steve
