Precision for internal calculations (gauging issue

Today I got an issue where the controller was complaining about an arc that would trigger the gauging error.

The code is automatically generated, that normally do not present errors, but I was checking it with the help of a CAD.
At the end the issue was that one off the coordinates needed to be:

-2.2614
instead of the value that was being used:
-2.261
that was rounded by the software that generated the software.

So, for this particular job, I needed to have 4 decimal places.
My question is where can I change the trigger condition of the gauging error? There is any config value or it needs to be changed on the source code?
Thank you

Hi

My question is where can I change the trigger condition of the gauging error? There is any config value or it needs to be changed on the source code?

It is in the source code, see
src/emc/rs274ngc/interp_queue.cc
src/emc/rs274ngc/interp_convert.cc

I think it might be a lot of work to change that, can you prevent your CAM from rounding down on arcs ?

regards

Thank you for the reply.
Yes, I can change the CAM as I made it, but I was hoping that there were a setting on lcnc, as this issue is only a problem on lcnc. Others controllers use the code without triggering the error as I tested, and normally all use only 3 decimals. This way I need to add the number of decimal places to display on the CAM that also give me a lot of work.
