Hi, How do you go about swapping filament with the Titan? I tried it as with my wades extruder. - heat to 80 deg C (PLA) - Quickly back out filament. This gave me a clean change every time. But trying the same thing with the Titan gives me troubles. The very end of the filament that comes up from the hotend is a bit deformed from being melted and gets stuck in the white (3 mm) filament guide. I guess I could cut the filament and just feed the new in as I extrude. But that is only good for change if color in the same material. I do not want to do that if I change from ABS to PLA or the other way around. Much less so when going from ABS to a flexible. So how do you guys change filament?
