Hello,
I have a weird bug occurring when printing with dual extrusion.
I will describe the circumstances:
I'm printing parts combined out of Ultimaker Nylon (Print Core 1) and Ultimaker TPU 95A (Print Core 2).
The parts come out nicely, but when the print is finished, the Nylon always gets stuck in the print core. The core even gets pulled back into the print head. Then the wizard for stuck material appears.
When i follow the instructions, print core 1 gets heated up again and clicks back down hard when the Nylon is hot enough. (It seems to be free at this point)
I still have to remove the bowden tube and cut the material to finish the wizard. Then it gets unloaded.
As if that wasn't enough, after finishing the process, the print bed violently falls down without much resistance from the Z-steppers.
Long story short: I think the printers workflow when unloading the material has a bug. After printing the last layer with TPU, print core 1 doesn't heat up again and therefore fails to unload the Nylon properly.
I would appreciate some help - maybe i'm doing something wrong. If not, maybe this could be looked over for future bug fixes.
Thanks in advance.

Thanks for that.
I see a lot of logs about things timing out, both network requests and processes inside the printer itself. I'll forward these logs to the embedded software team so they can have a look what's going on.
In the mean time, you could try a firmware factory reset via the display and see if that improves things?

Thank you for the help.
After resetting the network connection everything works again. It was a problem with our local network.

We are having exactly the same problem - ethernet connection works, i can view the camera over the network.
In addition the print over network in cura doesn't work anymore.
Reset both the printer and the digital factory didn't help.
All of this worked until last week, i don't know what happened in the meantime.

Sadly i didn't find a solution - now I even have the problem occurring with another Filament - Polymaker PA6-CF.
I remove the tube so the Feeder doesn't Push the Filament through the nozzle with the wizard. Then it can be unloaded.
The print bed also falls down after the wizard finished.
What i did is replace the front fan because i thought the filament gets stuck in the tube of the core.
Nothing changed - the printer seems to make a cold-pull but can't do it because the PA is too sticky.
Is there a way to override this cold pull?
It's not very efficient when i have to remove the filament manually after every print - if i wanted to do that i could have bought a much cheaper printer.
