Try this, load the program and edit it, go to the end of the last line and hit enter a couple times.
save and run again.

Pete,
Did you get it fixed yet?
I have almost the same setup you do and all of the same problems that you do as well.
the only difference is that I use Copley amps and and have had no problems with them.
I have the C11G board (random Estop), Teco VFD (sometimes the motor just growls and doesn't start) and Mach goes into Estop every time I edit a program (computer problems)
It sounds to me like you have encoder feedback issues. did you coil your wires and zip tie them together when you were getting ready to sell?   Richard

Yes, moving the z axis upward will make the angle steeper, pulling the cutter away from the sides.
Sorry about the photo's ,that was as close as I could get with my camera, download them to your computer and you should be able to zoom in.
My machine cut this pretty good, maybe just 3 or 4 thou into the corner and equal on both sides.so I think the gcode is ok.
your machine looks as though it is cutting more into the x axis than the y axis so you may have some x axis issues.
as far as machine setup goes, my settings are - no backlash comp.,exact stop(CV mode off),everthing else is pretty much default settings
my motors are tuned with the amplifier software, so that woulld not help you.
Remember, once you get your axis set up good you have to change the gcode back to original settings                       Richard

Here is the gcode back, I added spaces and line numbers. I annotated where you need to raise the Z axis.
Make sure you are satisfied with your XYZ settings and that the angle of your cutter is correct before making changes to the program.
There two pictures to show what the wrong angle will do.

Hope this helps

Two More Things
make sure backlash comp is turned off
If You can post the section of code that is the problem, some one here may be able to see if there is a problem
I can also run it to see what I get

After reading my own post I was wondering if someone changed the amount Z is raised when this was ported?
That would change the angle of descent and give you nothing but problems

this is how I programmed it
Cutter moves into corner and stops (bottom of cut)
Z raises (top of cut) (do not move this position)
X and Y Move (these are what I adjusted)
X Y Z move together downward to the same position as "bottom of cut"
program proceeds
Notes
My divit was tapered, it cut off to much at the top of cut but was ok at the bottom, so adjusting the x and y values was all I had to do
If the tool is off at the bottom that means it is not going back to the position it started from (mechanical problem?)
You could adjust both values( the same amount) but you would have to set them back to the original position before proceeding, I would want to why it did it in the first place.

I had the same problem you show on the corners, I think that my problem was caused by the EM (spiral tapered) sucking itself into the material as it went down.
There was enough flex in my Z axis to allow it to do this. I solved my problem by adjusting the X and Y values at the top of the cut until I got the corner I wanted.
Good luck.

I posted the last file while at work, I was just looking at it and it looks like this is possible
My only question is about the enable and exception pins, I have four solid state relays on
my system ( I only need 2 ) and there is not enough pinouts listed. I will get my meter
out tomorrow and see if I can figure that out. I do have a mobo that might work for
you, Myself I am more interested in getting this machine to work with mach, I have
programming to do, and do not want to work in dos and learn artisan gcode. Eventually
I will put servos on this machine and get rid of the remaining artisan hardware.

I found this doc on the web, it describes a bridgeport conversion to artisan hardware
