i got this as a reply wich solved the download speed, after this i reformatted the sd card and the degredation message was gone, i did notice the speed difference between the stock card and a Sandisk ultra:
For the connection please try this:
I understand that you have already tried many things, but please try my suggestion in the order I have wrote them even if you have done it before.
As a first step to solving the issue, I would like to ask you to:
1 : Unbind the printer from both the Handy App and Bambu Studio.
For the APP, you go to the 3 dashes on the top right of the screen and select “remove device”.
For Bambu Studio:
- go to the devices tab
- open the printers tab (top left corner)
- hover over the printer en click the icon with the arrow
2: sign out of Bambu Studio
3: remove the BBLprinter device from your phones Bluetooth settings
4: reset the printer to factory defaults
5: start the set-up and bind using the app when requested
6: when this is done, sign in to Bambu Studio again and the printer should be there automatically
Could you test the above and let me know if it helped?
Should it go wrong in step 5, can you please make a video of what is happening?
Regarding the wifi network: it should be a dedicated (so not dual) 2.4Ghz network broadcasting on a separate SSID.
Should you have a firewall installed (either software or hardware) make sure to open these ports: Printer Network Ports | Bambu Lab Wiki
Should the above not work, please try the exact same thing in the same order, but instead of connecting the printer to Wifi:
1: set up a hotspot on your phone with wifi turned off
2: connect the printer to the hotspot during the setup process
If my response helped solve the issue: please let me know which step helped.
If it didn’t solve, please let me know at which step the process failed.
