3d Printing - Switching from PETG to PLA and Avoiding a Clogged Print Head

PETG and PLA require significantly different settings for extrusion and bed temperature. PETG requires a higher extrusion temperature than PLA as well as a higher bed temperature.

When you switch from PETG to PLA, you need to make sure there's no residual PETG in the print head or else it cause clogging when printing with PLA at a lower temperature.

This video shows what I do when switching from PETG to the lower temperature PLA.
