    Default Scales on 4020

    Hi!

    is it possible/meaningful to equip a 4020 HT (1999, AC axes) with glass scales?
    Or is that too expensive?
    What else do I need besides the scales and cables?

    On an AC machine , I would think it would be fruitless to do so. They were offered on older dc machines to bolster accuracy , But they also caused many problems.

    I am a real fan of linear scales, I have 1 micron magnetic scales on all of my machines. About $120 / axis. They automatically correct for backlash (within reason) and any ballscrew error. On the issue of backlash, there is no substitute for having a tight mechanical system.

    Having said that, I have no idea what wiring and setup / calibration issues you might run into to install on your machine.
