Out of nothing - at least for me - Cura AppImage fails to start. When starting via command line, the following error message appears: ./Cura.AppImage PyInstaller/loader/pyimod02_importers.py:352: DeprecationWarning: the imp module is deprecated in favour o f importlib and slated for removal in Python 3.12; see the module's documentation for alternative uses Cyclic dependency detected between "file:///tmp/.mount_Cura.Ay7SrYx/share/cura/resources/qml/Actions.qml" and "file:///tmp/.mount_Cura.Ay7SrYx/share/cura/resources/qml/Actions.qml" QQmlApplicationEngine failed to load component System: Linxu Kubuntu 22.10, kernel 6.2.10 Anyone any idea what happened and how to solve?

ok, that (stream directly Gcode) I did not know.... the only thing I am expecting is, that Cura works with an Ultimaker Printer via USB - so you are absolutely right about third party printers .... and as far as I understood, the third party printer manufacturer could provide by himself the necessary USB connection software in Cura, so it is anyway up top him to fix and care about this.

I would think it depends also on the hardware. My S3 has an USB port - and the data sheet says also that there is a USB port. So - I have to admit I did not grasped all the complaints - if Cura and an Ultimaker are having USB problems, then it should be fixed asap. If it is another brand, than I fully agree that there is no support. Again, dropping USB is not an option as long as the Ultimaker Printers have an USB port ... And no, you are not 😊 a monster , but Ultimaker as a company should give a much clearer statement about such things. I worked for a big IT company (two characters) and I know that not all HW and SW configurations can be economically supported... my last words regarding this ...

USB printing may also be a security topic. LAN and WLAN are not so secure than a PtP connection .... But anyway, the discussion about the development approach in Ultimaker is not a very useful one. At the end everybody who is not in line with the approach can select another software where the developers may be more "user friendly". But also, if USB is an option in the software it should work and be supported - else it should be removed. ( I personally use LAN due to the printer being located in another room...). My 5 ¢

Well, the size is ok but the color .... instead of being black it a very light gray. And the rest of the GUI is also not very rich in contrast. Seems that it switches als to - when using this theme file - light background etc...

Hi, one thing which made my life complicated with the new version - used OS is Linux (Kubuntu 21.10) : - Font size on a 4K screen tooo small. The work around I found for Version 4.5 (put a themes.json file ...) is basically applicable, but now the font color is "light grey" and not easily to read. Is there any documentation how to make an own theme ?

I got a replacement (collet + bowden) - due to warranty - but it showed after a short time the same behaviour. Ultimaker is invited to send me a second spare part set, but I doubt, that it will fix the issue. Since the bowden and collet was replaced, without a lasting effect, I would suppose some tolerance in the feeder itself may be the problem. So again, it seems not to be an collet/bowden issue ... I think it arises when someone is printing with the nozzle doing small, fast movements - ike zigzag. And that at the end is loosening the bowden from the collet. By the way, it shows only, as I mentioned above, on the first feeder on my UM3 - the second one is not affected.

Not sure, maybe the feeder for the UM2+ and the S3 are the same - but I am not sure.... As it looks, the printer of catalancabreado is an UM2+ - maybe you ask him directly....

Congratulations! For me it works since months... Well, so maybe this is a real improvement proposal for Ultimaker.... Feel free to put it on Youmagine- at the end you have finished it.

Great ! Please let me know if this fixes the issue also for your UM

Yes, for sure .... As youcan see, it bulges a little on the right side (in the photo). Maybe it would need a little more space at that side, 1 mm or so would do it I think.... Since it was the 5th iteration and does the job I let it as it is....

I already got a new set through warranty - collet and bowden. But after some time the problem came up again. On one hand I would doubt, that I would get a second warranty replacement and secondly it would not help after the end of warranty. So I did a deep dive problem identification and found, that it always happens when printing a long time with many short movements of the print head. The solution is, aside from replacing the colletm, to longen the short tube, where the collet is placed in, on top of the feeder. So the movement is no longer this hard. By the way, it only shows up on the left feeder (looking from front), the right one never showed this behaviour. Any rewards for improvement proposals?

Thank you very much - yes, that's it. Well, it uses a lot of material and normally I don't have have a problem with contamination, but good to know, just in case. PS: since there is a plethora of settings, I am sure I did miss over 50% even after reading the normal guides....

When using support on a dual extrusion (S3), Cura generates a second part: I only need support in the hole at the top of the red tower. The blue tower is generated by cura when using the second extruder for support. Red tower is printed by extruder 1, Blue support by extruder 2. When using only extruder 1 for printing AND support, no second tower is generated. How comes?

Hi, I had the same problem. I created a bowden support, so that the bowden is not moving at the outlet of the feeder. I own an S3, so I do not know if the support will work with your model. It is a bit tight at the right side with the lever, but it does the job for me. I created it with FreeCAD, so feel free to adjust to your needs. To apply you have to remove the bowden and insert it into the tube part on top. Then reattach the bowden and finally slide the part over the feeder. The movement of the bowden, especially when doing tiny zigzag lines is slowly loosening the bowden and then the pressure from the feeder and material is pushing it out of its hold. At least this is my diagnosis. UMS3.zip
