The script searches for the retractions and primes and changes the Max E Speed before and after. The speeds of the retracts and primes are not affected. The rest of the gcode will have a limit on the speed of the Extruder.
For example:
M203 E50
G1 F2400 E672.2831
M203 E5
G0 F3600 X248.112 Y134.88
M203 E50
G1 F2400 E672.8831
M203 E5
The script is compatible with Absolute Extrusion and Relative Extrusion and Firmware Retraction. The speed conversion takes filament size into account.

The settings:

I can't recall any of you being "Not overbusy".
I've been going through old feature requests. This one seemed to be doable in post process so I gave it a try.

Sorry for that 😅 we just released 5.9 and we are currently finishing the conan migration, which is a huge work and really needs to be done very soon. So hopefully in a few weeks we can have more time for side-tasks 🙂

I'm not pushing. The feature request is many years old so it just doesn't matter. I had the idea for a fix and ran with it.

I know, but it bothers me that we still don't have a decent Cura team and we don't give the community the attention it deserves. 😞
