I switched from black ABS to orange PLA. Now I know it's a little challenging because the ABS is higher temp and the PLA is somewhat transluscent, but I've run probably a meter and a half of PLA through and I still get the occasional black streak.
I even tried upping the temp to the ABS extrusion temp and extruding a slug of PLA.
What's the best purging practice?
