:confused: When I first ran the roadrunner file on Mach 3 as a test it was very small when I had my machine draw it out on paper. But I loaded the nest circle file and it drew a 10" diameter circle. My step settings were incorrect and once
corrected the roadrunner was much larger( 2" verses 7.5 ") my table has a work area of approx 50"x50". Now when I load the circle file I can't get it within the soft limits of my table size. Any ideas? Very confused at this point.
When files are written are they done in differert sizes such as mm or inches and their placement on the work area according to the table size designated.
I hope this makes sense to someone. Whenever I load the roadrunner file it will go to the bottom left of the X& Y cross lines. The circle is way out to the right out of my tables boundries.

The location of the circle is in the g-code. Post it here and I'll explain it.

How do I post a G Code that is in a Mach 3 program?

load the code in mach3. then click the edit g-code button and it will open the gcode in text editor. Then select all, copy, and paste here.

If you have floppys, you can copy it to a floppy and bring it to the other computer.

Here is the g-code for "nestcircle.tap in Mach 3
g0x50y0z0
g0z-1
g2x50125
g0z0

If your machine is setup in inches, that's a 50" diameter circle. Depending on how your IJ mode is set in Config>State, it either travels from X = 50 to X = 100 (IJ incremental) or X=50 to X = 0 (IJ absolute).

Also, you copied the code wrong. It should be
G2 X50 I25
not 125

The first line of code takes you to X 50 Y 0.
The second line plunges the tool 1"
The third line tells the tool to go to X50 y0, in a clockwise arc. The center of that arc is called out by the I and J. Since there is no J, that means it's 0. IN incremental mode, the I of 25 means it's 25 inches from the previous X location, which is 50+25, or 75. In absolute mode, the I and J are the actual coordinates, or X 25 and Y 0.
