  1. https://www.thingiverse.com/thing:4544757
  2. The Cable Clamp holding the Polybox tubing does not work. It slowly deformes the tubing until the filament is clamped too. I am using a tubing holder now that I made. If you are interested, I will upload it soon and post the thingiverse link here. The holder can be simply clamped into one of the slotted holes below the extruder.
  3. Thanks to your recommendation I have also bought a Polybox now. Because I want to use it mainly for 2,6kg spools I had to modify the box. The box is not high enough for xxl spools other than the 3kg spools from Polymaker. Fortunatly there are a lot of box extensions already on thingiverse. I also printed conical tubes for the rollers. My hope is that this will always keep the spool centered. I fixed the Polybox tubing to the S5 with a cable clamp zip tie. Otherwise the extruder pulls the tubing inside and gets jammed during printing. How did you fix your tubings to the S5?
  4. My S5 started to make some unpleasant noises when the print bed moved up and down. The issue was in my case that the white plastic cover at the back of the print bed carriage has deformed over time. One of the through holes in the plastic cover moved and was now touching the z-axis rod. This could also happen to your S5 printer over time. I will try to explain what I did to solve the issue. I also took some pictures from the parts inside with some comments. Before the repair: https://www.dropbox.com/s/nt96xhdoyvbb1ex/Before_repair.mp4?dl=0 After the repair: https://www.dropbox.com/s/21xoipf9ls8r62b/After_repair.mp4?dl=0 To remove the squeaking, I needed to drill the through hole of the plastic cover bigger: Remove everything from the backside of the printer (Spool holder and Filament Spools from the back, Cables…) Lay the printer with the backside on the table Remove the bottom panel of the printer (bottom panel is mounted with tamper proof torx M3 Torx screws) and break the warranty void seal (mine was already broken although I have never tried to open the printer before). I am also very surprised that the bottom panel is cheap plastic not metal and has big holes for the speaker. I highly doubt that this is according to instrument safety regulations. Unplug the speaker from control pcb (Wow, that is one big speaker for a 3D Printer, can be maybe used in the future for spotify music playback) From the bottom you can see two stainless steel sheet metal plates holding the z-axis rods in place. You have to remove everything in front of it so that you are able to pull out the rods through the bottom. In my case it was only the outlet fan on the left side. The fan close to the control pcb sucks the air in and the fan close to the power supply blows the air out Once you have completely removed the z rod you can turn the printer back on its feet. You have now access to the plastic cover through hole. I carefully used a step drill to enlarge the hole diameter. There is some kind of dirt gasket underneath the cover to prevent dirt coming into the linear bearings, so be careful not to drill into the gasket or the linear bearing. (The hole on the picture looks a bit horrible because I tried to use a scalpel before to cut away some material, which did not work.) I would not recommend a normal drill for steel. It will suddenly dig into the plastic and most probably damage the linear bearing. Then I removed all plastic chips with tweezers out of the linear bearing and blew it out. I applied some new oil on the bearing Put the printer on the backside again and carefully insert steel rod again. It must move freely through the linear bearing otherwise you have not removed all chippings. That’s it. I mounted everything back together (Make sure that the fans are oriented correctly, and the speaker is connected again, and the job was done. Some interesting side notes: Good Meanwell PSU USP-500-24 (Scheduled for obsolescence and will be discontinued by the manufacturer). Will most propably be replaced soon by something else. Great Trinamics TMC 2130-LA Stepper drivers (Heat from the drivers and the whole pcb is transferred by a thick silicon pad from the pcb backside to the aluminium dibond panel) Motion Control is still done by the classic 8-Bit ATMega2560 The rest of the firmware is running on this Olimex A20 OLinuXino Lime 2 board SparkLAN WUBA-171GN WIFI Module Great MOSFET for the 24V heatbed. Very low on-resistance of 0.4 mOhm Not that great: Power Cables for the heatbed are heavy stranded cables, not very flexible. I wonder how long they will last before they break. (Good thing: the WAGO Connectors for the heatbed wires on the PCB are great (I think they are rated for 30A or something) Some components are not populated on the PCB. Which could be a hint for future 3D-Printer design plans e.g. a second heater connection (Maybe the next printer will have active heating for the build chamber. There is also a connector for another temperature sensor) Not so nice: Some cables are not assembled that great e.g. the heat shrink tubing was pulled off on one fan cable. The soldered cable shielding was exposed. And The USB cable for the wifi module is too short and under tension. Overall, I can say: Very good, and high-quality electronic components like the above-mentioned parts but also e.g. the SUNON Fans or the MOONS Stepper Motor. The assembly is good but could be a little bit better. The mechanical design could be definitely better and is a direct result of excessive cost-cutting measures. I am confused that the electronics where not affected by these measures.
  5. In unserer Firma haben wir alle Arm-Türgriffe (ca. 40 Stück) aus Tough-PLA am Ultimaker S5 gedruckt und an diversen Flur-Türklinken montiert. Stabil sind sie auf jeden Fall. Sie helfen aber auch nicht zu 100%, wenn sie nicht regelmäßig desinfiziert werden.
  6. Paketklebeband verwende ich zuhause z.B. bei TPE. Das Transparente ist aus PP und sollte für sehr gute Haftung sorgen. Überprüft habe ich das leider noch nicht, da ich zuhause kein PP drucke. Das MAGIGOO PP lässt sich feucht mit einem Topfreiniger-Schwamm wieder entfernen.
  7. An der Arbeit drucke ich viel mit PP, dafür nutze ich immer den Magigoo PP Klebestift. Schon mal Paketklebeband probiert?
  8. Because each line of printed filament is not prefectly rectangular but more a rectangular with round edges, the line width is reduced to really fill the gap between lines. The main issue is not the smaller line width but the auto leveling height of the first layer. The distance is too close for all materials. There is a z offset plugin in the cura marketplace. Try using this and increase the gap size. The waves that you have at your first layer are typical for overextrusion with PETG. When I see them printing with PETG I always change the z offset.

    Cura Slice Problem

    Wie vermutet, ist das Problem schon im 3D-Modell vorhanden. Hier zusehen im 3D-Builder Ich habe das Teil im 3D-Builder (übrigens kostenlos) jetzt einmal reparieren lassen, siehe Stl im Anhang. 158657429_covermirdynamischenfuteilnichtdruckbar.stl

    Cura Slice Problem

    Schmeiß es doch testweise einmal in einen anderen Slicer. Dann dürftest du ja sehen ob es Cura oder das Modell ist. P. S. Lade doch einmal dein Teil hier hoch. Dann können wir es probieren woran es klemmt.

    "Print thin walls" aktiviert?

    Cura Slice Problem

    Ist das Modell irgendwie defekt? Hast du mal im 3D-Builder von Microsoft geschaut. Der versucht das zu reparieren sollte es defekt sein.
  13. Also, ich habe mit der 4.3 unglaublich viele ärgerliche Bugs erlebt und war froh als endlich eine neue Version herauskam.
  14. Great mod! How far could you reduce the retraction distance with your mod? Have you tried using the the Z offset Plugin from the Cura Marketplace.
  15. Using the external marketplace also does not work, I have tried that before. If I click on install it shows me that it was added to Cura. But the material is still missing in Cura. Do I need to connect Cura to the Ultimaker Cloud to get this working? I can't connect to the Ultimaker Cloud this is also blocked by the company firewall.
