    Mach 3 feedrate displays wrong on X axis

    Hello everybody...

    Does anybody know why Mach 3 would show a faster feedrate on my X axis then what I have set in motor tuning? I have it set to 400ipm and its shows 1077ipm when jogging around the table. Ive run a few test cuts and everything comes out great. If anybody has any ideas please let me know. Thanks! :-)

    Are you jogging the X axis only?

    What are your default units?

    It moves the correct distances?

    What version of Mach3?

    Yes... when I jog Y and Z indvidualy they both display correctly.

    What are your default units?
    Inches

    It moves the correct distances?
    Yes.. it seems to be very accurate.

    What version of Mach3?
    1.83


    Thanks.

    Could it be that I have two motors on my X axis and its throwing Mach off in some way?

    Has it always done this?

    You're using a 3 or 4 year old version of mach3, so I'd suggest a newer version.

    It didnt do it on my first machine but it only had one motor on X. If I remember right it started when I added the slave motor for X on my second machine. The version of Mach that I have was on the computer when I got it from a friend... Im not sure who its licensed to or how to go about updating it.

    If it's working fine, except for the feedrate display, you might want to leave it alone.

    I thought though, that I vaguely remember that as a bug, but it's been several years.
