wird sich defenitiv lohnen, da man durch die Unterschiedlichen Yokes schon einen bestimmter Druckbereich vorgegeben kann und man innerhalb dessen sehr fein einstellen kann.
Danke dafür. Dann werde ich das auf jeden Fall demnächst machen. Ich habe mir die STL heruntergeladen. Die Datei "YokeAndHub" gibt es mehrfach mit unterschiedlichen Maßangaben. Worin liegt der Unterschied? Ich nehme an, eines davon zu drucken genügt?
Hoi! Copperfill by Colorfabb is one of my favourites! I once printed a model in it, and the client could not believe it was possible... It is just fantastic!Q
Yes it is! I also use Bronzefill. I printed both on my previous printer (Creatr from Leapfrog) without any problems with retraction.
Now: My advice is to turn off retractions (yes, there are some bad-asses here who manage to print this material with retraction), but I dont.I use the stock feeder.
I already tried this. It maybe works when you print "easy" objects like a vase where you actually don't really need retraction. Most of my objects are scanned people. I need a lot of support structure for the prints. Here, it doesn't work without retraction. After a while the nozzle starts to clog and you have to pause the print and clean the outside of the nozzle. Otherwise the print fails. This is quite annoying if you have a 20h print and need to set your clock every 2 hours to clean the nozzle (especially at night :angry:)
If you have printed PLA, then ABS, then PLA (or Copperfill, which is PLA) then you will have carbon sticking inside nozzle. Clean it. Else you will suffer with every print, regardless of material.In that configuration you will find yourself in an upward spiral of temperature and downward spiral of speed, ending with 235/40 which is an unhealthy setting (and blood pressure), because cooked filament clinging to inside nozzle walls hinders the flow greatly.
On my previous printer I changed my material very often. Using all famous filaments I never had any problem with the nozzle after changing. Maybe that's an Ultimaker thing but I don't hope so. And so far, changing the filament on the Ultimaker wasn't a problem either.

Hi,
ja der Stock Feeder vom Ultimaker ist nicht wirklich einstellbar, da gibts nur sehr hart und noch härter.

You can only go from PLA to ABS if you first perform 1-10 Atomic Pulls. Epic instructions in English at www.3dverkstan.se.
