Setting up and using parametric macros using OctoPrint and various plugins. Along with other hints and tricks.
Run, don't walk, to https://plugins.octoprint.org/
and get:
OctoPrint Gcode Macros Plugin Create custom commands you can add anywhere: in your gcode file, OctoPrint’s terminal, gcode scripts, or other plugins to run a configured script.
Use macros for preheating your printer, levelling the bed, changing filament… Possibilities are (nearly) endless!
This OctoPrint plugin adds the ability to define GCode commands that execute local system commands.
You can also use this plugin(maybe)
Makes custom controls editable via the settings dialog.
This plugin helps you create, edit and delete your custom controls. You can easily access all the options in the settings under “Custom Control Editor”.
Also extremely helpful
Ok, first, I walked away from using Microsoft products in 2004 or so and have never looked back (except to laugh!)
If you want to do this on Windows (without loading up some Linux compatability programs) you are on your own...
That being said - Welcome!
Note:
To save yourself some heartache, place ALL your bash shell scripts in "/home/$USER/.octoprint/scripts/"
Why?
The directory is backed up and restored with OctoPrint Backup command! I even put my boot and crontab files there.
Here is my Controls Page using Custom Control Editor
That's a lot of stuff! Need it? No. But it is what led me down this rabbit hole...
And this is the little trick it taught me!
This is configured in Custom Control Editor plugin.
This was derived from GCode Systems Commands plugin.
(See the stuff in red at the bottom?)
So it calls "Variable.sh"

eval $cmd
exit
Specifically, this lets me edit my runtime variables file from the Control Tab.
It also lets me edit them from the Gcode file!
For example:
;TYPE:Custom
; custom gcode: start_gcode
; Inserted from post processor script in SuperSlicer that converts a text file of
; layer based actions manually entered from the slicers preview screen.

OCTO400 File=WhyMe.data Name=mine.my_State Value=false
OCTO401
OCTO402 Name=64 Value="Place O-Ring"
; The only action is to place an O-Ring at the start of layer 65 (see notes)
; I always stop after Layer 1 cause I ain't gonna print with a shitty first layer.

Each subdirectory contains my code and explains how it is used and how it is related to the other parts of my "system" (I am so funny). Enjoy!
