Behavior

• Describe the problem
  The Filament Settings/Advanced/Print speed override setting does not seem to produce anything different.

• Steps needed to reproduce the problem
  In the Filament/Advanced/Print speed override box enter a value, say 75
  Slice
  Observe that there is no gcode change in the file. The only change is in the metadata at the very end of the file.
  Please see the meld diff attached.

  • If this is a command-line slicing issue, include the options used

• Expected Results
  Per the tooltip description, I've expected that M200 is generated for that filament wipe in between
  ; CP TOOLCHANGE WIPE
  ; CP TOOLCHANGE END

• Actual Results

  • Screenshots from SuperSlicer preview are preferred

Is this a new feature request?

Project File (.3MF) where problem occurs

Upload a SuperSlicer Project File (.3MF) (Plater -> Export plate as 3MF for Slic3r PE 1.41.2 and older, File -> Save / Save Project for SuperSlicer, Slic3r PE 1.42.0-alpha and newer)

It is again super useful feature.
There should a usable, very good speed control/settings for the wipe tower.
Currently, it seems to be fixed , depending on the filament type.
For me, it would decrease the filament switch time significantly.
I recall others complaining the petg not printing because the wipe speed it too high.

Okay, I axed my code when I merged with the new prusa wipe tower (new files, and I forgot to find a way to re-implement it, as the previous hooks doesn't exist anymore).

I'm trying things to re-create it.

Also, the previous behavior of default slower print with flex filament seems also axed.

Keep up the good work.
Just a feedback, not sure what the behavior should be preferred.
Prusa has chosen a fixed speed and slowing down via M220 for the wipe tower.
I believe it does obey the volumetric speed limit though.

My speed preference would be
1- The print speed/vol speed limit defined in the print/filament settings
2- Optionally a speed percentage via "Print speed override"
3- The same print speed/vol speed limit/print speed override should also apply to the empty grid
Currently , I am doing this (item 3 and fixed speed up from current feedrate) via a post processor.
The time wasted at the wipe tower is pretty significant, especially when printing small one-off , single copy models.
My post processor cuts it down a bit, quite worthwhile if I recall correctly.
Though , it is the slicer that should do it in the first place.
