Hi,
I've read the assertion many times that ijk is better than radius and
always assumed it to be correct; but by how much.
Few of us run machines and are 'new' tigjht ;-) Maybe I've not looked
in the right place(s)
for an analysis or for demonstrated interp of circles with some kind of
error band. Any proof and or experimental evidence?
Just poking the bear. ;-).

One option is set your post processor to post radius not ikj values.
That helped me once.
They are much more forgiving

Something is fishy between the Y values.
You have Y4.xxxx in the first list and Y0.xxxx in the full listing.

I see it in your gcode file listing

Where is the decimal point in the X value of "End=(X14444, Y0.8964)"?
I would say it is X1.4444 and expect this is a typo when you entered
this
in the email.

We had been cutting with the same gcode when suddenly it came up with
an
error:
Radius to end of are differs from radius to start:
Start=(X1.4208,Y4.8728)
Center=(X1.4208, Y4.8964)
End=(X14444, Y0.8964)
r1=0.0236
r2=4.0001
Its got to some config issue. The same file runs in the simulator just
fine. That r2=4 is curious. We are cutting in a jig using fixture G55.
We had touched off the Y by 4 inches to run the file again. That worked
fine. We more the Y back 4 inches and touched off again to set the G55
back to its actual 0,0 origin. When we ran the time, we started getting
this error.
This is the code in question. Its complaining about line N70.

Any ideas about what is wrong? We are running LinuxCNC 2.7.15.
Thanks.
