Forgot how noisy ver 01.04 was.
Loaded defaults but had problems linking in iPhone app. Have to:
Turn off router Wireless 5G.
Remov printer in Bambu App.
iPhone: “Bluetooth settings-> My Devices” Forget This Device
Followed your same steps:
Load Firmware 1.04 via iPhone Bambu app:
settings->Firmware Version->I want to downgrade to a previous version
Factory Reset
Setup and Calibration
Test Print benchy (excellent result. Just like new first print)
Update to 1.05.02 via Smartphone App
Calibrated using onboard display keypad
Test Print again benchy (excellent result. Just like new first print)
Printed a multi-color clock face.
Wanted to test with something with a lot of platter coverage.
Very good even print across face using textured plater.
So far it looks like the issues are gone.
