Ups, that's not good ☹️. Have you enabled prime plob for the second extruder? If not, that may be the culprit. Regards

Hi, whic Cura version are you using? I guess 4.9.0, which had that bug and acually is outdated. Try the new version 4.9.1. Regards

In the new "Mesh Tools"-plugin there's also an option to choose the desired unit: Regards

There was a beta release, as used to, but obviously, the beta testing users didn't do a good job... I guess Ultimaker is working for a bug fix with high pressure.

Hi, not exactly, but there are a lot of versions online at Youmagine or Thingiverse. For example: https://www.youmagine.com/designs/easy-clips-for-ultimaker https://www.youmagine.com/designs/ultimaker2-bowden-cable-clip https://www.youmagine.com/designs/ultimaker-2-bowden-clip https://www.youmagine.com/designs/ultimaker-bowden-holder-clip Regards

Hi, the Ultimaker part number for the ball bearing (F688-2RS) is 1220, according to the official parts manual (see page 7) UM3_Parts_Manual.pdf The official resellers should have it, even if not listed on their HP, all they need is the part-#. Regards

If you think so .... I'm out.

I'm sorry to say so, but you're wrong. If the distance between lowered bed and head is shorter than the controller thinks (which means, shorter than it should be), the bed hasn't lowered enough, it didn't lower too much. Check the Z switch as suggested, as it's easily be done, also check, if the Z enstop works at all (in systems menu).

Hi, it sounds a bit confusion, as moving past the Z end stop (lowering the bed to much) would normally result in to much space between print bed and printhead at start of print. Your problem may result in the bed stopping before the Z end stop is reached. So you should check the small pit where the Z end switch is located for debries blocking the Z switch. Regards

I can confirm that.

Indeed, prime blob of extruder 2 is not performed. For extruder 1 it works as used to.

Hi James, what's happened is called layer shift. The reason is a lose pulley or a skipped belt, so you should check that. Ensure the set screws of the pulleys are tight and the tension of the short belts is ok. https://support.ultimaker.com/hc/en-us/articles/360011598659-Check-the-tension-of-the-short-belts https://support.ultimaker.com/hc/en-us/articles/360011490220-Check-for-play-on-the-axles-of-the-Ultimaker-3 Regards

Hallo, der erste Check wäre zu prüfen, ob der Federspannungsindikator am Feeder auf der mittleren Position steht. Beim Neuladen von Filament ist das Problem, daß der Schnelllauf nach der Bestätigung nicht die gesamte Länge des Bowdenrohrs überbrückt. Vor dem Bestätigen sollte sich das Filament also bereits gut 5cm oberhalb des Feeders im Bowdenrohr befinden, dann dauert es auch nicht ewig, bis das Material aus der Düse kommt. Der Ladevorgang ist im Übrigen für den Drucker unschädlich und bricht auch irgendwann von selbst ab. Grüße

Ok, I understand. I misunderstood your question. If it' just one object on top of another (and another object ontop...) and each objects has an unique material and colour, you could try to do it "manually" by stacking the objects in Cura and manually change the filament, using post processing scripts (for example "pause at hight" or "change at hight").

Multi material with a single extruder? I think this only works with a special setup as the Prusa MMS or the Palette. But that's totally out of my knowledge. Regards
