There are 3 different ways to swap between materials types.
Swapping the nozzle
Swapping the Print core/hotend assembly
Swapping the printhead
Each way has its own benefits and risks. It is your judgement to evaluate what risk level you’re comfortable with.
Swapping the Nozzle
Low time intensive option
Low labor intensive option
Low cost intensive option
High risk of clogging option
Procedure:
Move the axes to X150 Y150 Z300. This will give you working room to remove the nozzle.
Heat the printhead to 100C. This will soften the material inside the hotend and make it easier to remove the nozzle.
Using a 7mm nut driver, remove the nozzle.
Heat the printhead to the printing temperature of the material currently in the hotend.
Feed the new material into the printhead and run the “LOAD” macro at least 3 times or as many as it takes to see the new material. This will push out the old material in the hotend.
Using tweezers or pliers, remove the extruded material.
Install the new nozzle.
Swapping the Print Core
High time intensive option
High labor intensive option
Medium cost intensive option
Zero risk of clogging option
