Description of changes with respect to RC2:
Check if file is complete
In previous firmware version, there was bug which caused that some complete files were wrongly reported as incomplete by the printer. This was happening with files sliced in S3D, because of slightly different end g-code. This issue has been fixed.
Sorting files in SD card menu
In previous firmware version, files order in SD card menu reverted to unsorted when print was finished. This has been fixed,
PID calibration safety check
At the beginning of PID calibration heating is turned on and nozzle (or heatbed) temperature is rising.
For improved safety, we are now checking if measured temperature rises as fast as expected during this initial phase. In case that there is for example faulty/disconnected thermistor, measured temperature doesn't rise and PID calibration is then terminated, heating is turned off and thermal runaway error message is shown on LCD and serial.
