    Re: DIY CNC not cutting correct size

    Chains, direct connect, it doesn't matter. All machines have backlash. It all depends on how much is present and how it is managed.

    But, I think you are on the correct path to fixing it. Keep...

    Re: DIY CNC not cutting correct size

    I think wizard has it right. Another thing you can do is cut the square and the circle forward and backward (clockwise and counterclockwise). If the two cuts are both off in opposite directions...

    Re: David A's New 2x3 Bench Top CNC

    I agree, just saying that its the only Haas machine that actually presents a problem with twist. Anything with a cast base can ALMOST be done without thinking. I'm not sure what Haas' reasoning was...

    I acknowledged that he had adjustable feet, that's why I asked about twist. It is possible to level a machine and take the twist out of it. The only one that I ever had problems doing both was on...

    Yes, it is a 3D problem. I actually had a customer that cut some insanely small profiles on parts and I went in every six months or less and checked / adjusted the machine. They were quasi threads...

  21. Re: 10k rpm greased packed spindle, how to make it quieter
