@Connor-6 this morning (UK time) I uninstalled & re-installed the app again. Since then, it appears to have been working ok & I have been able to sign in & print several things over wifi this afternoon & this evening... hope this helps.
The process is straightforward—download the installer from the link above, then follow the video tutorial to complete setup. Should you encounter any complications, let me know and I’ll guide you through.
@Karen Hi. Had same troubles during hours and jours ...
AND next day, tried to connect with bluetooth and it worked !
2 metters far from the printer.
Please let me know if it worked also for you 🙏
I had a similar issue with my printer. Middle of the night, it started jamming. I had to take off my hotend and remove the nozzle. Filament got dried up inside it. Try maxing out the temp and feeding filament through the tube into the hotend to unstick any filament inside. DO NOT LET THE FILAMENT FFROM THE TUBE MELT IN THE HOTEND. You will have a major issue if it melts.
A version of Cura comes on the SD card with the printer (5.2.0, I think)
Open any file you want to print (.stl / .3mf / .step) and select the scale icon on the left toolbar (it looks like a square with an arrow coming from one of the corners). You can then scale to a set dimension or percentage of original size.
You can download your favorite files from websites like:
ThingiverseCults3DFree3D
After downloading, you can either upload them to the app for printing or use computer software like Wiibuilder to slice and prepare them for printing. Here is a tutorial for Wiibuilder: Wiibuilder Tutorial
