You were printing with ABS an then switched to PLA.Did you Purge the ABS from the hot-end by running PLA to the ABS temp and Pushing Extra ABS from the Hot-End.
I'm pretty sure I did - heated it up to 240 C, removed the ABS filament, then pushed the PLA filament through the extruder so that it (should've) caught all the remaining ABS.
Please explain to me how to...
