Flashforge Finder not extruding during print, fine during Load Filament

[tlawrence84]

Hi All, I've been using my Flashforge Finder for about 5 weeks now without any problems, however recently i changed the filament in the usual way and now it wont extrude PLA when printing. When I use the Load filament option, the filament is grabbed by the motor and drawn down, I can leave this a minute or so and see that the filament is moving freely through the extruder.

However when I print, nothing wants to come out. I first thought the bed was too close to the nozzle, so moving this away, even creating a large gap that should make the filament just extrude everywhere doesn't work. I don't hear any noises coming from the motors like the filament is blocked. I'm printing at 215c, although this is using the same .gx files as prior to the issue. I'm stumped as to what I should try to resolve this
