    Re: PM-25MV Spindle Drive Replacement

    Nope. But I'll be replacing my drive/motor with a Delta AC servo kit at some point. Might be worth looking into.

    6.8mh inductance?. Ouch!. You'll be lacking at high velocity. You will just constantly stall out.

    Re: Z Height Inaccurate As Job Progresses

    There's a grinding noise every so often. That's prob not so good. Sounds like motor step loss. Check your coupling isn't slipping too.

    Re: Mach 3 Issues - Pirate Version?

    I never had any issue with Mach3 when it was used with a pirate license.
    But.... I also only used Mach3 on WinXP operating systems via parallel connection (32bit only).

    Will help to tell people which control board it is using?.
    Mach3 is OK but as Craig said. It's old and Mach4 has replaced it so it's Mach4, uccnc or LinuxCNC for options.
  30. Re: Leaving Mach3 for UCCNC - Hardware migration question

    Another option is to get hold of a retail version of win7 sp1. Once it's installed that's the end of it. You don't get the updating, it stays as it is and doesn't mess Mach3 up.
