⬢Take the first extruder and release all eight M3 screws.
⬢Remove the printed part from the motors.
BEFORE YOU PROCEED READ THIS! We are about to release the lock screw on the pulley. Proceed with extreme caution as you can strip the screw!!! If possible apply some grease first.
⬢Very carefully release the lock screws, be careful as you might strip the screw's head or thread.
⬢Remove the pulleys and put them away, so you won't mix them with the new ones from the MMU2S kit.
⬢Repeat this procedure for the second extruder. Together you need 3 motors without the pulley.
⬢Use one motor in the MK2.5S assembly for the Extruder.
