Dynamic speed vs nozzle temp - firmware or slicer or both?
-
hello
FDM/FFF Printers are getting faster and faster by every week in the community.
Carbonfiber rods, Mosquito magnum+ with almost 100mm3 flow allows for extremely fast extrusions even with small nozzles.
Printing large objects fast generally isnt a problem. But once small detail is introduced (benchy roof pipe for example) that requires lower speed for cooling, or lower speed for the fine details.
So what if we could type in the Slicer:
Detail temperature
Speed temperature
Heater VIN readings (to accruately time the temperature changes)Slicers already have Minimum layer time for cooling. But when I print PLA at 280Celcius to match the flow, that is just waaay to much for that benchy pipe.
So if the slicer could set temperature to 210C some time before the pipe comes, the printer could gradually slow down the speed match that temp.
at 280C it runs 300mms
at 250 it runs 200mms
and at 215 it runs 60mms (just exampes)That way we theoretically would get a perfect benchy at the highest possible speed.
Thoughts on this?
am I being uselessly creative here?
best regards

Is the Mosquito magnum+ watercooled? It would make much more sense then...
Otherwise with a heaterblock wrapped in a silicone sock, it would take forever to cool down. (*)
Anyway it's an idea which might already be achievable with a daemon.g macro? Unfortunately M220 (print speed factor) only works for *all speeds including travel speed*) Oilcooled heaterblock would be the best way. (...runs to the Patent office

@o_lampe watercooling the heatsink would make little difference in my opinion. As the magnum already had very low thermal transfer.
So that's why I thought the speed could just dynamically while the temperature is decreasing and increasing.
It also cools a lot quicker while extruding, since new filament will absorb the heat
