    I see ... I'm expecting to see an extremely rigid machine then, otherwise it's not worth it.

    You could consider calibration to compensate for the inaccuracy in a C7 screw. Mach3 allows you to do this in a couple of different ways...

  5. I dont use Mach3, The machine is being made out of solid steel :-) So rigidity is very high. Machine is powered by servos!

    That sounds generally awesome! I'm sure screw calibration must be available in EMC.

  7. I dont know about EMC as i use USBCNC

    Oh, fair enough. Don't think that can be calibrated, without writing your own program to edit the Gcode... which is tricky.

    I can supply C5 and C3, but it is not a stock item.

    Marchant Dice have rolled C5.
    I can remember in the distant past finding a site that listed far more ball screws, but can't find it now.

    Any more details about the mill?
