A "better pause/resume script" question


What is the problem?
I use a combination of absolute- and relative-extrusion GCODE files. Upon pausing a print, I notice a string of filament as it pulls off the part. I'd like to compensate for this in the built-in scripts but I can't just do the following in the pause script:

G91 E
G1 E-1
G90 E

...because this would potentially wreak havoc after the resume because I didn't start the job with absolute extrusion in half the cases.

I noticed some snippets are available. Is there one for remembering the previous extrusion mode setting?

What did you already try to solve it?
I searched in Google, the FAQ/Guides here.

No, this is currently not tracked by core. But since you can extend GCODE scripts and their available variables through plugins you could write a plugin that takes care of that for you.
