Google it for more , but it ' s the tool you use to turn veggies into noodle shapes ! <| sep |> It ' s okay . I was into Taylor ' s bachelor buddies in Vegas . We all have our unspeakable moments that we ought to be publicly shamed for . <| sep |> So , I think I was missing a little context from before . I had PETG in the nozzle before this ~ 245 degrees extrusion . I pulled the PLA out then did a cold pull with PETG as the pulling material . Then I ran a print with PETG everything went just fine . I think the source of the problem is that I printed PLA without clearing all of the PETG out from previous prints . What is the correct procedure to ensure all hightemperature material is cleared of the nozzle before swapping to lower temp material ? In this case it would be swapping from PETG 245 to PLA 205215 ish .
