RE: What are all the parameters that control tip thickness?

- As I was fixing things, I would find that sometimes the filament would fuse two different colors together, and have either a blob or stringy hairy bit at the tip that was being ejected from the printer. These bad “tips” are a common thing that is discussed on Prusa message board and all kinds of ideas are out there what to do about them, including very fancy post-processing python scripts for GCODE. I was going to do that, and I was also going to print a mod for the selector that many people seem to swear by, specifically because of the misery with the tips that kept on clogging up everything and causing numerous problem. BUT! There were two secret things I found.
- *** EXTREMELY HELPFUL MOD: The following settings change my tips from being terrible constantly to being perfect ALWAYS. Go to prusslicer, filament settings (for EACH filament type you use with MMU!)—>Advanced —>Number of cooling moves CHANGE THIS TO 3. Then click RAMMING SETTINGS, and change Ramming time to 3.0s. The former was recommended deep in some support document from Prusa, and the latter was recommended by a Prusa support agent via email. Therefore these are not HACKS, these are suggestions from Prusa. They are so incredibly helpful, they should have been default.
- I wanted to print a modified selector to help with the tips issue, but I decided against it because as soon as I did the software change above, I no longer had ANY problems with tips. At all.
