Topic: Changing Material - Leftovers in extruder

I was printing with black ABS and then switched over to some blue PLA. Every so often, the extruder will spit out some leftover black ABS. Usually it's just really small amounts, but occasionally it's large bits that throw off an entire print.

I expected this for a little while when I first changed the material, but I've done quite a few prints since then and it's still happening.

Does anyone have and advice on how to completely clear the extruder when you switch between materials?

You just have to purge for a while - there isn't any special trick
