Summary
- Improved Wi-Fi (ESP) flashing
- UI fixes
- Known issues
This is the second release candidate of the upcoming firmware 4.4.1 focused on fixes and optimizations. Kudos to the community for reporting the issues!
Improved Wi-Fi (ESP) flashing
Previously, in some scenarios, flashing the Wi-Fi ESP module failed after the firmware was updated. In case the printer was restarted using the hardware button below the LCD, the ESP remained powered on and didn’t power cycle. It was necessary to turn off the printer completely and turn it on again.
The issue was found on the CPU pin shared with the RTC (real-time-clock) and in some random scenarios, it was impossible for the system to send a “reset” signal over this pin. Developers have fixed this problem and now the ESP reset should work correctly.
UI fixes
Overlapping buttons fixed
The dialogue for credentials creations sometimes showed part of the button from the previous screen.
Button displayed outside the screen
While trying to print G-codes sliced with a filament different than the one already loaded in the printer, the printer displayed one button partly outside the screen. This issue was affecting all languages except English.
Known issues
This release is affected by a bug, which prevents the printer from overwriting the already existing Wi-Fi credentials file on the USB flash drive with a new blank one. This will be fixed in the upcoming release. For now, if you want to create a new credential file by the printer, make sure there isn't any on the flash drive.
