    uccnc (cncdrive) is popular and looks pretty painless. I'd probably look here first if determined to use Windows.
    linuxcnc also popular but maybe a little more pain...
  2. Re: Think something went wrong with my ballscrew

    Looks like some heavy grinding(?) on that flange. If enough heat is generated it could cause problems ? Just a guess based on no experience.

    Re: Some CNC'd signs

    Is all the finish work done with a brush or is something else going on ? To make that farm sign I would have to paste in a picture :)
    If it's all brush work that's some high level skill.

    Re: Reinforce X2 mill

    Here's a mod I started on my X2 but never completed. The idea was to have bolts or set screws coming in from the sides.

  21. Re: What did I buy? Old machine, new tech, take a look.

    If it's a Kerk lead screw it will have some form of anti-backlash. You could ask the seller the screw/nut model # as Kerk has several.
    My preference would be a ball screw over acme.
