so see what your C compiler thinks of /* this is a /* nested comment / which "shouldn't" break things but will /
fwiw lines like that should use a ;semicolon comment so the firmware can skip the whole thing
You are quite right : I can't think of any language that does allow nested comments like that.
According to "The NIST RS274NGC Interpreter - Version 3"
3.3.4 Comments and Messages Printable characters and white space inside parentheses is a comment. A left parenthesis always starts a comment. The comment ends at the first right parenthesis found thereafter. Once a left parenthesis is placed on a line, a matching right parenthesis must appear before the end of the line. Comments may not be nested; it is an error if a left parenthesis is found after the start of a comment and before the end of the comment.
So clearly it is a bug in the software generating the GCode. The generator was BfB Axon 2.0 beta 2. The previous version I used did not have this problem. I will raise the issue on the BfB forum.
Therefore I will close with "Not a bug".
A comment such as
( fill DiaphragmPeriod(layers): 100 )
is parsed incorrectly, leading to incorrect commands being executed.
