+1 on both suggestions...I've had only 2 clogs in 2 years following this practice...and that's with a stock SD2 Hotend and switching to EcoFlex and back to ABS. 

I just got the E3D for my Ord Bot build and with the .4 nozzle I'm sure this will even improve those stats.

So, wouldn't a simple firmware change to force an extrusion now and then when sitting idle solve this problem?

Being able to clean the stuff out with the string is kinda handy.

Mine did clog last winter because my Z Axis height was screwed up and the nozzle was jammed with the green painters tape I was using on the bed (lol).

After the headache of clogs it was the best upgrade I've done. Any clog I do get is in the tub and easily cleared by removing the hotend, heating, then pulling it out with tweezers.

As recommended all over the forum, upgrade to a E3D if you have not. With an all metal hotend, clogs are rare, and it will allow you to print with other materials a stock hotend would not appreciate.

Either way:
*If heat settings are too high, the filament will melt before reaching the nozzle. This will eventually lead to a clog and charred fragments in the barrel.
*Try to avoid cheap filament. Some may be very intriguing on sites like Amazon, but even with high reviews they may be a disaster...pumped with moisture and inconsistent diameter.
*In my experience, PLA clogs more often. And if over extruding PLA, it can cause the printer to "gum up".

Let us know what kind of setup you are using (e.i. make and model of printer, style hotend, any modifiactions you have made, etc.) This will allow us to help you further. smile
