I want to write code that will take a .txt file that may look like: N1 G1 G90 X0 Y0 Z3. N2 X1.2751 Y1.82 (G Code - can be thousands of lines long. Each new line starts with N__. Leading and trailing zeros are omitted.) Find every instance of X(and the value attached to it) and add a U(with the same value) afterward. For example, after running the software, the above will now look like: N1 G1 G90 X0 U0 Y0 Z3. N2 X1.2751 U1.2751 Y1.82 If been chasing various ideas and haven’t gotten very far.
