My printer is a Da Vinci 1.0a, runnning reptier .92 and using cura to print

1. Bed wont stay leveled. Ive auto leveled it on cura and the lcd screen. Ive even tried manaul leveling. Evrytime i click print the bed ignore the leveling settings ive saved and lowers itself a inche away from the extruder

2. Sometimes the extruder starts clicking and wont print/feed motors wont move. Idk if the filament is clogging it but sometimes it feed a then it the plastic goes though and starts clicking

3. When printing starts it takes 30 seconds for the filament to come out of the extruder. It starts bubbling for a bit then comes out
