Yesterday evening i have been trying to print a few upgrades but after coming home after an hour, it is printing in the air because there is to much filament dust inside the extruder. Is this because the filament that is being extruded is getting to soft so the gear grinds parts off? I never had this problem before.

I'm highly unconvinced that dust in the gearing is related to your problem. If the material is still being extruded, then "in the air" suggests the base layers may have slipped, or your belts are slipping, either of which will lead to a huge lateral offset, and thus the "printing in air" problem. It's possible but less likely that the extruder feed gear itself is slipping.

If you can post a picture of one of these situations, that would help a lot.

I will mention in passing that there are several models for filament guides at thingiverse.com . Putting one of these on your machine will eliminate scraping and the resultant dust.
