I moved up to a 0.6 nozzle and was going crazy with not getting the same quality as on the 0.4.
Any and all changes such as temperature towers/arachne engine/halving acceleration did not produce a good result.
The only thing that helped was slowing down the printing speed which kind of defeats the purpose of the 0.6.
Then when trying a calibration vase cube at various speeds i noticed the following.
It prints perfectly at under 70mm/s speeds but above that i get bulges in the corners.
After messing with it for several days i tried setting the fan to max and at 100mm/s speeds i got the result on the left with the stock 40% fan and 100% fan speeds.
Are there any changes i can try here? It’s currently looking like the cooling is insufficient opposite the AUX fan and the only option i have is slowing down the print. At that point i might as well go back to the 0.4 nozzle as it’s way better tuned out of the box.
This is all with BASF Ultrafuse PLA at 0.2 layer height, 0.62 width, 220 temps
Small prints like that especially in vase mode do not allow enough time to cool between layers.
The filament profile has ‘Max fan speed threshold - Layer time’ and ‘Slow printing down for better layer cooling’ option. They are the options you should be using to allow sufficient cooling when needed not an overall speed reduction.
That said the print speeds are fast enough at 0.4mm to be slowed by filament volumetric flow limits which means larger nozzles don’t reduce print times by very much. The only good use case for larger nozzles is not getting bunged up by filament with stuff in it and for wider walls in vase mode.
I had similar issues with the 0.6, I am really struggling to get decent print quality without slowing it down too much.
Considering how nice 0.4 prints out of the box just at 0.98flow settings (bambulab filaments)
I am giving up on the 0.6 and wait for bambulab to make it more “plug and play” since I am using bambulab filaments
