sometimes slowing down a print doesn't really help when printing a single object.
Take this one for example (Ieyo Bust, https://www.thingiverse.com/thing:297846):
Depending on size/model there's sometimes very fine features along Z which need a certain amount of time to cool
down. Slowing down the print using "Speed Overrides" on the Speeds tab doesn't really help here - because it will
keep the extruder above the object even longer, making matters worse.
In cases like this I ended up using a simple thin walled box, scaled to a height to fit the object. While this does work it does
come with some drawbacks. How long it will take to print that tower depends on various settings (perimeter speed). And unless
you're into modelling a specific "cool tower" for certain objects you end up with more material and time wasted during the
print than necessary.
So what if instead of slowing down the print there would be some kind of "cooling tower" option inside the speed overrides?
It could generate some kind of "U"-shaped single wall feature which adds/removes print time depending on the set layer duration/threshold.
So instead of slowing down 30% because of reaching the limit -> add the difference (actual vs. threshold layer time) to the "cooling tower".
A solid base for adhesion would be a good idea. And I'm suggesting the "U" shape because thin objects (box, 1mm x 10mm x z height)
tend to wobble a bit after reaching a certain height on printers using a moving bed as y axis. A simple cylinder would probably also
work for this.
Trying to explain this:
Instead of slowing down the print, print time is added to the "cooling tower".
Seen from above:
Simple base for adhesion and single extrusions (current or minimum extrusion width to save material) at a given speed.
"Cooling Tower" is printed at 5mm/s -> each second below the speed overrides threshold adds another 5mm to the "U"-shape (maybe including necessary travel times).
