Re: first layer supports not sticking

.... I slowed down the print speed to 60, ... 60 what ? percentage setting at the printer ? with which print speed has it been sliced ? do you use linear advance settings ? for such a structure I wouldn't print faster than 30mm/s for the first few layers, without lin-ad. furthermore I would recomme...

Re: Hilfe gesucht zu 3D Druckertest und Passgenaugkeit der Teile

Hier ein paar grundsätzliche Überlegungen zum Thema Passgenauigkeit: :idea: Man muss beim exakten Designen von Objekten die ineinander passen sollen immer mit berücksichten, dass die eingeschränkte x/y Wiederholgenauigkeit bei der Positionierung des Druckkopfes prinzipiell immer dazu führt, dass Löc...

Re: Layerverschiebung

Ist der Layer Shift in x oder in y Richtung (also rechts/links oder vorne/hinten) ? Die Antwort auf die Frage könnte schon mal einschränken, wo man nach eventuellen losen Ritzeln oder sonstigen Problemen suchen könnte. Manchmal gibt es auch einen Layer Shift wenn du mit einer zu hohen Volumenfüllrat...

Re: life adjust Z - my way

... So I backed up and tried -.910 and -.905; both seemed pretty damn good. But for some reason -.910 was smoothest, so I've stuck with that. But still has a few rough spots. Does it sound okay? yes, sounds ok for me. if you still have a few rough spots, it might be a good idea to check the filamen...

Re: Print curling

:idea: did you thoroughly clean the pei sheet with 99% isopropyl alcohol ??? or even acetone ? and didn't touch the surface with your hands before printing ? maybe your pei sheet is a little bit "worn out", so "refreshing" it with 000 steel wool might be a good idea. by the way: at the thread, where...

Re: life adjust Z - my way

I recommend to "fine tune" it down to +/- 20µm. check out -920 and -940. you should get a closed and consistent surface, without seperated strains, at a thickness of 0.20mm. remember, if you still got strains but no closed surface even when lowering the tip of the nozzle much further: check and cali...

extruder printed in orange, a real problem ?

Hi guys, after printing the extruder parts for the MK2(s) -> MK2.5 upgrade in orange abs, I noticed that prusa doesn't ship the upgrade anymore with orange filament. they are only going to be shipped with black petg now, due to issues with the optical filament runout sensor. is there a real problem ...

Re: Why is the extruder pulley made of Brass ?

Joan is right (as usual), the brass hobbed pulleys are no longer available at the spare-parts section of the prusa shop. :roll: just noticed that because the brass pulleys of my two printers (genuine MK2 and selfmade clone) are worn out now and at my clone I get extrusion interruptions during the pr...

... Could the extrusion multiplier be the culprit here?
yes, might be.
