Plasmac Post Processors

The error is from line #4 in the original gcode:

linuxcnc.org/docs/devel/html/gcode/g-code.html#gcode:g53

Thanks, got rid of that error but now there is another one.
Operator error:
G-code error
Radius to end of arc differs from radius to start:
rel_err=97.5794%
I have attached the error.
I have found a lot about this on linuxcnc forums and the solution given is to change the tolerance in linuxcnc:2.4. [RS274NGC] Section  n 
It says to add it in the ini file. I can't find where this is meant to go. I tried adding it but it didn't work. I couldn't find this center arc radius tolerance in any of my config files. I tried increasing the accuracy on the cam side but it didn't change anything.

 

A 97% error seems quite large.
Does the PP output the I & J values as absolute or incremental distances? The LinuxCNC default is incremental.
linuxcnc.org/docs/devel/html/gcode/g-cod...ml#gcode:g90.1-g91.1
 

I tried lots of different things and in the end I have changed to sheet cam.
I use the nestmaster to create a nest and then use sheet cam to create the gcode for qt plasmac... seems to be a good solution.

I am having the same problem with "Radius to end of arc differs from radius to start" with a +90% error rate, using the fusion 360 post. I am able to post out some parts that will run and some that dont. All of theese have previosly been run with no issues on a Mach3 plasma with the same cut settings. Files 1001 and 1005 runs fine. But not 1002 and 1006? Any idea on how to fix this?
 

SOLVED: Doug solved my problem, now it works great!
