I am having a bit of trouble with my 3D printer at the moment, and thought I could gain some wisdom from our 3D printing geniuses (plural?) here on LMR.
My extruder keeps blocking, I am using PLA, printing at 190 degree's, with a hotbed of 57 degrees
The printer is a makerbot replicator 2 clone, called the duplicator.
Each time I clear the blockage (which takes an entire day basically) I can feed through the filament again, however the steppers start to "tick" and slip again over time, and about half an hour through my next print, it all blocks up again.
This is a link to a video of the extruder, after I load the filament in, after cleaning the blockage (bear in mind the nozzle and extruder have had an acetone bath are very clean at this point) You can hear the ticking and see the filament coming abit juddery.
I am relatively new to 3D printing and would greatly appreciate some guidance in this area to get my printer back up and running!
Added some extra images at the request of jinx
Extruders (you can see the blockage, please ignore the ugly wiring on the left)

My thing-o-matic settings in replicatorg for slicing.
Since these imges were taken I have successfully cleared blockage, and put the extruders all back together again.
