M3D filament not extruding well (anymore)
Suggested remedies for 3-D printers which are not extruding required amount of filament:


First, check the temperature of the extruder. Try 220-225C to see if that improves the problem.
The second step is to increase the flow of the filament (increase mm/sec) for extruder speed.
A final step is to increase distance between extruder and base-plate. If the extruder is too close to the baseplate, there may not be enough space for the filament to begin the printing process.


Another possible source of lack of material extrusion is a clogged extruder. To solve this problem:


Retract filament using jog control in software
Heat extruder 20-30 degrees Celsius above normal extrusion temperature 
Disassemble Extruder, use small thin wire to remove blockage (guitar wire as suggested below)
