Hi,
the Roadrunner program is in inches. A g20 code should allow the program to run on a metric machine though. You should try some other tests before worrying about the Roadrunner.

Jog the machine to roughly the center of the table and zero X, Y, and Z.

MDI:
G0 X100
X0
X100
X0

That should cause the X axis to move back and forth 100mm. Does it do it?

Do the same thing with the Y axis:
G0 Y100
Y0
Y100
Y0

Now you need to make sure the Z axis works:
G0 Z50
Z0
Z50
Z0

Let us know how you get on.

Can't believe it. It ran and cut. I used g20 and then ran the roadrunner. Worked. I think I might redo everything (reload nach3) and set it ton inches. Probably better off.
Thanks so much for your help, although not sure if I'm out of the woods yet, But going to have a martini.
Thanks again.

Hi,
NO!....don't do that. There is no need. If you are happy in metric leave it that way.

If you have a Gcode job in inches you code G20 at the beginning and Mach will interpret the numbers as inches.
If you have a Gcode job in mm then code G21 at the beginning and Mach will interpret the numbers as mm.

How does one know what the units are? and why wouldn't Newfangled Solutions caution folks about that. I've been trying to get it to work since Feb this year. You solved my problem in one post. I agree, although I'm in the US, I think metric is so much easier than standard. No fractions to deal with.
Thanks so much again. I hope some day, I'll be able to help others the way you helped me. This a great site with great people.

Hi,
this is a Gcode problem not a Mach3 problem.

To be effectective at CNC you are going to have to become familiar with reading Gcode. There are online tutorials.
Or  'The CNC Handbook' by Peter Smid is sort of the CNC bible.

I was going to post images of my Gecko build, but having some issues. Will return.
