Hi @gr5 I tried to get an employee on the phone multiple times and called them in the netherlands but I always got told that they do not give tech support via phone. Hi @Torgeir I will try turning off thin walls and will send the project files as well as some pictures

So Ultimaker support reached out to me and told me that they do not know what the problem is and I should pay a service 3d party technician who has the expertise to deal with that problem. I am truly out of words. I will never work with an Ultimaker product again. Do you know who would buy this peace of junk with 20kg of filament a few spare parts and a spare bed and a few printcores some new some clogged.

Hi @Torgeir I tried changing the values and got following result: The top surface looks way better, but is disconnected from the walls. Do you have an idea how to fix this? Thanks LJ

Hi @Torgeir I was looking at my profile again and every linewidth was set to the nozzle size: 0.4 for 0.4 nozzle and 0.25 for 0.25 nozzle The only setting I could find that was set to 1.2 is the wall thickness Thanks LJ

Hi I do not get error 65 and the mesh was okay. Also the print cores are clean. So this is very odd to me Thanks Leon

Hi I was able to do the test today. It was 17 seconds at 200°C using PLA

Hi @Dustin Thanks for your comment. I did not know that the post processing was broken for a time so that is really good to know. Unfortunately the problem still remained with other prints. The printcores were cleaned and even new printcores were tested, so I do not think that this is the issue The profiles are set up correctly (double checked that today) and the front fan is spinning and orientated in the right way. Even though I have no errors other than an occasional bedleveling error (mostly due to residue on the nozzle or plate). I was told by a third party technician that he heard of them failing from time to time. Can this really be the issue because the cable seemed fine to me? Thanks LJ

Hi @gr5 Thank you! I will try it ASAP Thanks LJ

Hi @Torgeir I tried diffrent printcores in different configurations and it did not change. the problem is independent from which printcore and printcore slot is used. Thanks LJ

Hi @Torgeir Sorry for the late response. -My firmware is the 8.2.0 for the R1 (double checked and yes that is the right one) -Cura is at version 5.3.1 (also tested 4.8 and a 5.2.X version) A project file can be found attached Thanks LJ UMS5_Part1.3mf

Hi. Thank you for your answer. So I checked these points: 1) Yes it is really PLA 2) The settings are the default engineering settings. I even did a clean new installation of cura just to be safe and checked with a collegue if it the settings are the same. Also got confirmation from ultimaker support 3) Front fan is new (orientated in the right way) and is working as intended 4) trying to extrude filament via the move command leads to grinding after a few seconds (prime blob works fine and extrusion when changing filament also looks right). I think it is because of the speed at which the filament is moved but the ultimaker support did not give me an answer on this issue. (They always ignore questions) Is there another test I can do? Maybe check the extruders with the bowden tube removed? 5) I did not check with weights but I could not stop the feeder from pushing filament with force 6)tried different cores: 2 Ultimaker AA0.4 and one Solex A0.25 7) tried four different spools of PLA but not step 4

Hi, The Bowden tubes are good and clean. The underextrusion happens on every print on the top and bottom layer. I switched back to using Ultimaker black PLA and the issue remains the same. I fiddled around with different slicer versions which did not help. I checked every moving component and everything seems fine. My collegues tested if it works for them and they have the same issues.

Hello everyone, Because our company does not want to put more ressources into our underextruding s5 (500€ in spare parts, about 100 hours of research and fiddeling and phone calls, project delays, etc.) we want to sell the printer and exchange it for something else. The next investment we could have tried, was replacing the extruder stepper motors. Does anyone know someone who buys old and/or broken printers in order to repair them and resell them? Thanks in advance LJ

Hello everyone, I again need help with my UMS5. This machine causes nothing but problems for weeks. Now the biggest one is underextrusion Things I checked -Cura Settings are Ultimakers recommended Engineering Settings -Flow tower looks the same at every level -Printcores are new and clean -Feeder tension is right and the feeder wheels are clean -Bowden tube is clean -No scipping or clicking noice So the next thing I would check are the E-Steps. Is there a way to calibrate those? Is it possible to see the current E-Step value? Thanks in advance So the next thing I would check are the E-Steps. Is there a way to calibrate those?

It did actually work. Eventhough it shouldn't it just worked without me changing something
