Take X axis scale mode and switch it from +1.000 to -1.000
Run the program mirrored 3 more times.
see what it does

Good grief my friend,

Simply supply the gcode for review ................................,

Heres the gcode as text.  Not sure how to get it into an XML file.  Export from Cad as a dxf, then post processor makes it a .tap, then straight into Mach3.  Sorry, pretty new to this.

That is actually not the Gcode for the piece pictured before, thats the gcode for another example I video'd the run on.  Just having an issue with the video right now.  You can see that in Mach 3, it is telling the X axis to move, but it is not moving.  Will try and get the video up shortly

N0050 G53 G90 G91.1 G40

Your G-code runs in Machine coordinate system: G53 Move in Machine Coordinates
Absolute distance mode: G90 (set absolute distance mode)
Incremental arcs: G91.1 - incremental distance mode for I, J & K offsets
Tool compensation off: G40 Compensation Off

Why do you run in machine coordinates? Do you have homing/limit switches?

Second, show us your code with circles.

Chech this: http://linuxcnc.org/docs/html/gcode/g-code.html or https://machmotion.com/cnc-info/g-code.html

1. Post the gcode file used in your intial post about drifting.
    It should be a text file and is not an xml file. Probably has the ext of  (.tap ) .

2. Post your xml file that you are using for you machine. The xml file defines all the parmeters
    that will be used by Mach3 on start up. The xml file is located in the main Mach3 directory ie;
    plasma.xml.

We will simply review the gcode. Then we can review your xml for how your machine is configured and
provides general understanding about your machine without asking you a lot of questions.

Stay focused..........,
RICH

xml file posted here

https://drive.google.com/open?id=1uwvsEUVPyV0TQtdnZtBcp3AsVNUf-65x

Also, the video in that share drive shows the machine running a pass for the previously posted gcode.  If you watch it, disregard the fact that it is not lined up with the previous pass as I started it from a different point.  At 26 seconds, you can see the display on Mach3 showing X being commanded to move, but no movement on that axis.

The video can also be seen at this link if it does not work in that file

There are no homing or limit switches on this machine other than on the Z for setting head height.  This seems to be a pretty basic machine, and was set up to be "plug and play" for the previous owner.  However, the previous owner is dead and the guy that set it up no longer does service calls, so were kind of stuck figuring it out.

Patience,
I think people here are losing that because all that was asked for was the g-code file that went with the pen output you showed first. Instead you are doing everything but what was asked and you are getting no closer to the answer.
