Using S3d to slice, need an example

[thorkon]

I'm just getting started with using commands and gcode altering so this is still new to me but I want to start getting into color changing. I was wondering if I could get an example of what I would input into advanced options Find Line (regular expression) if I were using simplify3d and trying to pause at layer 14. Is this it:
; layer {layer},.*

Then I'm assuming I need to input m commands in the inject gcode. Are the base ones that are shown (M117 Change filament
M0) enough to get a basic color change?

I'm reading up on the commands now and see that m0 stops the printer and m117 displays the message. I'm guessing I would probably want to input commands that would move the hotend away from the print.

I'm using a anycubic Chiron. (Can't recall the exact Marlin its running at the moment until I get to it at home, buts its whatever comes stock). Thanks for any help!

Most of the times (?) M0 would do the “move head out of way” but it’s most of the time a “try and learn” game... it’s a matter of if you enjoy playing the game ;)

And yes, the regents should work

regents/regex/. (Thanks iOS spellchecker!)

Thanks for the fast resposne! I'll give this a shot and see how it goes :D.

Am I able to pause the layer height at different heights with this? (10,23,37,etc)?

Edit: I'm now seeing I just have to add a space between the numbers in the layer number field I think

Comma separated works well

I get the same error as @thorkon
Below is a piece of log. How can I fix it. What am I doing wrong?

I accidentally found a solution. I looked at the G-code and found that there was still a space before the layer.

G1 E-0.9000 F2400
; layer 3, Z = 0.600
G4 P1

Added a space before the layer to the expression and the plugin worked.
; layer {layer}.*?
