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?

Are you jogging the X axis only?
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.

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.
