No, you have to buy the CC Red core for the ruby nozzle.

If you mean the AirManager and the MaterialStation, then no, they are only for the S5.

I think it's easier and safer if you buy a whole PrintCore. It's questionable if the parts are available at all, because it's not intended that you can exchange single parts.

Please post here in English or post it in the language specific area.

For me, the selecting issues are fixed in 4.3 beta, haven't seen it anymore.

Just an idea, haven't tried it yet : Clariant PC-ABS https://www.igo3d.com/mediafiles/Sonstiges/Clariant/TDS/PC+ABS.pdf

You must always load an STL file to be able to print something. Cura is only a slicer but not a program to create 3D models. This was not possible with version 3.x and never will be. Is it possible that you mix Cura up with another program?

You should be aware that abrasive materials will wear out your feeder and nozzle very quick. So if you have to print with CF or glass filled materials, you should upgrade to a Bondtech feeder and a hardened nozzle.

Can you elaborate your issue a little bit more, currently I have no idea what you mean.

If you can't loosen a part well, then heating up is the wrong way. You should let the printing bed cool down and if that is too less, put the printing plate in the freezer for a few minutes. It can also help if you put an extra layer of glue (UHU stick) on your bed. This layer then dissolves more easily and if necessary you can also help with a few drops of water around your object. These printing plates such as Buildtak are quite useful for problematic materials, but for normal PLA the adhesion is too strong.

I would get a spare cable to be on the safe side, if it ever causes problems, it will come again.

Ok, then I guess it is also the cable.

Good to hear you fixed the issue, and thanks for the feedback. Can you check these instructions: https://ultimaker.com/en/resources/19485-stopped-temp-sensor-bed So you get also the BED TEMP Error?

This corner looks generally a bit strange. I would say that your bed is not very well leveled, but the S5 make the active leveling, so this could not be the reason. So maybe your glass is not really flat? You see it in the whole corner, that the first layer is not squished into the glass as on the other corners. (or maybe it looks like that only on the photo) Another issue could be that the glass was not clean enough, some grease from the fingers or something like that. You could try to turn or position the model on another place on the glass, to see if it makes a difference and if the problem is only in that spot.

It is more like the engine humming sound and thought that this sound cannot be the steppers. Then I checked the back fans and they were on full speed. After I aborted the print, the fans went back to normal speed and were not noticeable anymore. I could just feel the airflow. I wouldn't worry about that anymore, the sound is unusual, but certainly nothing to worry about.

So, I have tried now to start a print and paused it after some layers. The head goes in a parking position in left front corner and the print core cools down. After some time the hotend fan in the middle of the head stops (this is when the temperature of the core is < 40°) The noise I hear after that is in my opinion a mix between the two back fans and the stepper motors, but I have the feeling that the bass or the "body" of this noise (I hoper you understand what I mean, I have no idea how to explain it better in English) comes from the fans on the rear of the printer. I mean I can hear also the steppers but when then they are very silent compared to the two fans. Maybe the two fans also stop after some time, but I haven't tested it. The sound itself, I would say it is unusual, but not alarming, so I have not the feeling it sounds unhealthy or something like that. It may sound like someone has the engine running from their car, but this car is relatively far away. Somehow it has something of a dull engine noise. I hope it helps a little bit.

Never heard about it, that the message comes up during a print job. Should not happen and seems that this is a bug.

The sound from a stepper sounds not healthy, but I haven't heard it yet on the S5. I can check it in the evening if my S5 makes a similar sound when I pause a print. I guess homing the head is not so accurate to get then back to the correct position. The home switches are only normal microswitches and they have some tolerances. So it is safer to keep the head in place to guarantee the next layer starts exactly where it should.

OK, then I was wrong, thought that the print core remains on temperature. So when all fans are off, the sound can only come from the steppers. I guess they are still powered to keep the position. Because of your Z-screw I take everything back again, on the video it looked very dirty, but on the photo it looks good.

Hmm, it is correct that the Nylon filament absorbs a lot of moisture from the air, more and quicker than PVA, so you have to keep both spools in a very dry place and depending on your air humidity also during printing. But I think you mean if Nylon absorbs the water during the dissolving process of PVA. Good question, but I don't think that this is really a problem, but haven't tried it myself yet. And in case it absorbs a little bit, the model dry again when you have dissolved the PVA supports. If that were so sensitive, you wouldn't be able to expose nylon printed objects to higher humidity, but that's no problem.

But when the estimated print time differs, then you should also see a difference in the preview after slicing. In most cases and especially when your model has thin walls, the slicer ignores these walls, resulting in a semi-finished object.

That's good to hear. So you have a little army in your desk drawer.

Maybe I am wrong, because I don't do it often, but normally when you pause a print, the print core remains at temperature, or not? And if it remains on the temperature, then also the front fan runs. And for me it sounds like a fan, but that could also be caused by the video. BTW: You should clean your Z-screw 😜

Yes, I thought so, my answer was meant more for the OP, so it is clear that it does not work with the UM3. 😉
