Hello everyone, I'm facing some persistent issues with my 3D printer when attempting to print new car models that have curved surfaces. Initially, my prints with flat-bottomed models went smoothly. However, with these new curved designs, despite adding supports, the printer frequently fails, grinding the material. Here are the steps I've tried so far: Lowering the retraction speed to 35mm/s Cleaning the feeder and the wheel Cleaning the bowden tube Hot and cold pulls (core cleaning) Adjusting the tension on the spring screw by loosening it incrementally Experimenting with printing speeds of 90 ..read more

Hi   I am experiencing an issue where when my filament runs out, the printer pauses awaiting a filament change, I change the filament and restart the printer.   When the print continues i have notice the layers have shifted considerabley as shown in the images below, This happens on a number of Gcodes with different models, these models also print perfectly fine when there is sufficient filament without stopping.   It seems like the print head looses the positional data and restarts offset   Does anyone know why this is happening and how it can be resolved.   Cheers&nb ..read more

Ultimaker's new Factor 4 model continues to use 2.85 mm filament. What is the rationale for this choice, aside from maintaining compatibility with the existing Ultimaker ecosystem, such as print cores interchangeability and their material portfolio?   Moreover the Method line uses 1.75 mm filament.   Considering that 1.75 mm filament allows for finer control, potentially better surface finishes and access to even more materials, what advantages does sticking with 2.85 mm offer ..read more

Hello, I have a problem with the Extruder 2 motor driver. For this reason, I want to use the Extruder 2 connector on the motherboard for motor connection. I made this connection, but ext1 is still active in software, so the engine connected to ext2 does not work. Extruder number 2 cannot be selected for the Ultimaker 2/2+ printer on Cura Software. Therefore I cannot activate ext2. How can I solve this problem? Thanks in advance for your help. Can ..read more

Hello, because I wanted to replace my heater block, I had to replace my heater cartridge and my temperature sensor wire. These were stuck firmly in the block. Everything is connected as it came out, but now it won't start at all. Very disappointing of course. Who knows? Thank you in advance ..read more

Buenos dias desde argentina , estuve imprimiendo bien todo este tiempo y hoy al generar un stl nuevo no pude imprimir mas, si cargo un stl anterior la maquina imprime pero si genero un simple cubo y lo compilo en cura ya no lo imprime, primero pensé que era un problema del archivo que modifique que era uno descargado, así que opte por crear un simple cubo en fusion 360 y exportarlo como stl ... tampoco me lo imprimió, incluso los parámetros para que empiece a imprimir como temperatura del extrusor o de la cama caliente llegan a los rangos indicados y la impresora no se mueve ..read more

Hello there   We're using the first version of the S5-Modell in our Company (The one with a Robot-Logo on the Side). Recently like 1-3 months ago the Connection went randomly lost. After checking the Logs, I couldn't identify the problem at first sight, so I contacted the Ultimaker-Support Team.   A young Supporter was answering me 3-4 hours after my mail and wanted to see the logs, so I provided him with those. He told me afterward, that the WLAN Card couldn't connect properly, so he sent me the safety instructions to open the bottom Cover of the P ..read more
