I have ran the same program now 10 consecutive times. Of the 10 times running 6 of those had "%" sign added randomly when machine is reading the code and not in one specific place which is really strange. I am stumped at this point on what it is. Any ideas ?
Thanks in advance

Need more information before I can suggest what is happening.

I assume you have a G-code file (Without % signs) and you are sending the file to a machine via a serial link (possibly dripfeeding). If so, there could be an error with the Communication setup itself either cable not correctly wired or incorrect serial communication protocol. "%" was often used to replace an unknown character in the data.

It is normal to program a % sign at the start and end of your program, in some controls it will put it in if it is not there, I always use it even if the control does not need it, you set this up in your post processor

What it does is signals start of data during file transfer.
