Mach3 and G-Rex / Re: Mach3 Turn X Axis issue

Thanks Rich,

The machine uses stepped motors.

The motor tuning appears to be correct, but the movement shown on the DRO doesn't translate to the movement on the machine?

I'm a bit baffled to be honest!

Mach3 and G-Rex / Mach3 Turn X Axis issue
« on: October 19, 2016, 01:30:38 PM »
Hi all,

I'm relatively new on here and am after a little help.

I run a small machining business from home and have just purchased a Denford Orac CNC Lathe running on Mach3.

Z Axis runs perfectly and is bang on size wise, but the X Axis is way out and doesn't seem to repeat at all.

It was converted over last winter by the chap I bought it from and it has never really been used by him.

Any ideas on how to sort the problem, the solutions probably staring me in the face but I just can't see it!

Any help appreciated.

Hi all I'm new here and could do with a little help
I recently purchased a small milling machine equipped with mach 3
I've been using the machine manually with no problems, however today I imported a dxf file from autocad, loaded the g code and when I run the program I have found
that the actual movement of the machine is greater than the movement shown on the DRO.
Mach 3 is not something i'm used to, could this be a simple problem or something more serious, any help would be greatly appreciated.
