Very much so. Could it be the opposite problem then? What’s the slower speed look like?
@Justin_Nesselrotte 10mm/s so perhaps the nozzle oozes during the slow parts, and is refilled during the fast parts, making the print overstuffed during the slow printing and overlean during the fast…?
@Mark_Wheadon @Justin_Nesselrotte that would go some way to explain what I saw where the first 50 layers were overall faster due to a third speed/colour (F1000) and zero underextrusion … only in later layers where there were just the 2 speeds of F1600 but mostly F500 that I got underextrusion at the beginning of each F1600 block.
Very interesting theory. What happens if you scale the speeds up?
Wow!
I’ve released the code into the wild: https://plus.google.com/+MarkWheadon/posts/5PVTBnXKU2E
interesting
So nice
