Comment line in Gcodes

Hi, I need to comment this lines in my gcodes

REGEX
^M220 S100 ;Reset Feedrate

by that

;M220 S100 ;Reset Feedrate

I tried to use the Replacements but i think this does not work.

That is correct?

  • Looks correct if the spaces are matching. You can easily verify in https://regex101.com/ if an expression matches.

    Only thing is in replacements no further replacements may occur. Otherwise endless recursion would be possible.

    I try this

    Regular Expresion: /M220 S100 ;Reset Feedrate/g

    Gcode to execute
    M220 S80 ;FEEDRATE 80 Personalizado


    this matches on regex101


    But not work.

    for this Gcode

  • You need to omit the javascript marker / and /g in your expression. Also you should start with ^ if it matches from line start to improve comparison speed.
  • I try that and not work.

    Can you check that on your test setup?

  • Set replacement to: M118 Replaced M220
    So I can better see if it was executed. Then executing your demo code above and as you see in output it got replaced:

    So not sure what you are doing wrong. I assume you have no trailing space and are using latest 1.2.0 release.
    If you want to replace all M220 S100 you can omit the ; .... part. Just in case comment got stripped, but it doe snot get stripped in my version so at that stage it is still there.
  • I have great news.

    Replace code works.
    I did not realize it because the speed is not updated in the interface.

    But yesterday I put the same file to print on two different machines and one finished before the other. So it works ... I don't know if it was when I removed the part of the comment or something else. But it works.
