Firmware 1.2.3-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?

• Fixed tilt jerk in calibration
• Fixed rehoming tilt when printing
• Others

A detailed description of changes:

Fixed jerk in calibration

Some machines have encountered problems during the calibration process while measuring tower height. The tilt mechanism couldn't handle the pressure from the printing platform and skipped a few steps. The current in the tilt motor is now increased to withstand the applied load.

Fixed rehoming tilt when printing

The printer now properly rehomes when it loses a step in the movement up (e.g. printing extremely thin layers using tough resins).

Others

• Removed unnecessary movement in Home Tank function
• Prevent rehoming while measuring tilt times
