@Phaedrux said in How to limit extruder feedrate without limiting retraction speed:
They won't become more advanced if the limitations are hidden from them. If the extruder speed is limited as you suggest, then printing speed will have to reduce to maintain it.
I'm perfectly fine with max extruder speed imposing a limit on XY axis speeds. Car manufacturers often electronically limit max car speed to a specific value above which tires could break apart. Another example could be a combustion engine rev limiter which also in theory limits performance but also prevents mishaps.
I want to do something similar by limiting max extruder speed to a value above which the extruder will not work properly anyway by either skipping steps or losing traction on the filament.

Use a slicer with a volumetric limit function?
The feature is not worth enough to warrant a slicer change just for this feature (I would lose other important features to gain this one), which is why I'm looking for a way to limit this in DUET/RRF.
@Danal
Are You saying that if I use M203 E600 to limit extruder speed to 10mm/s, that limit will only work for printing moves and not for retraction moves? That is what I want to achieve but from the tests I run a few months back that wasn't the case with stock firmware at the time and retraction moves were limited to 10mm/s.
