PFW-1336 

The following situation is now fixed, steps:
1. Load filament through LCD
2. Load to nozzle through LCD
3. Before filament reaches Fsensor => turn off the printer
4. Wait a few seconds and then turn the printer on again
5. Start a print through the SD card
6. Printer will unload and then re-load the filament

Previously in step 6, the printer would start a print without any
filament loaded.
