red text blocks

[Battwell]

i ran some code yesterday with lots of tiny movements- a carving which was very detailed but shrunk down to pretty small.
when running the code i noticed a fair few blocks of code highlight red instead of white as it was running. - generated with vcarve pro
was wondering if it was because the line lengths were shorter than my cv settings so it was being ignored?
block rate was so fast i couldnt go back to check the code
first time ive ever seen this during a run.

by the way- came out lovely!

You mean the g-code view showed some text lines in red color?
The red colored text is always something which the UCCNC does not understand or in other words it is not code to be executed, e.g. notes in () and line numbers etc. or code with wrong syntax which the software don't understand.
The texts are colored when the file is loaded and not on g-code file runtime, so it can't be machine settings problem like CV problem, it is simply that those lines or text chunks are not interpretable codes.
E.g. with the code N010 G0 X10 the N010 will be red colored, because there is nothing to interpret and run in that code.

Ok.
Never seen it before while running
I.e. Chunks of code showing red while running.
In the middle of the program- making extremely small moves I presumed.
