Firmware 1.2.1-FINAL for Original Prusa SL1
Hi guys,
this is a final version of the firmware recommended to all users 😎 Note that this update is sent primarily via OTA (over-the-air). Before flashing the firmware manually, check your internet connection on the SL1 first.
What is new?
This is a bugfix release
- Fixed UV LED exposure timing
- Auto adjust tower profiles for reliable homing
- Fixed bugs
- Others
A detailed description of changes:
Fixed UV LED exposure timing
An integer overflow, which prevented longer exposure times, was fixed in the motion controller firmware. Now the exposure time set in the printer's interface should match the real exposure.
Auto adjust tower profiles for reliable homing
Homing of the tower uses a new algorithm that finds automatically optimal axis sensitivity. This feature allows the printer to home reliably, replacing the old system which required manual tweaking in case of unreliable homing. All the issues with tower homing should be resolved by this change.
Fixed bugs
- Fixed missing sleep in tower/tilt sync wait
- Fixed ALSA state restore in new systems
- Erase MC EEPROM on factory reset
Others
- Various improvements in test code and build scripts
- Improved log extraction speed
