Procedure

Follow the steps below to change the filament of the 3D printer to a new type

1. Heat the nozzle up to the printing temperature of the material in the machine
   1. Push the knob on the display
   2. Turn the knob to the right to scroll down to the Temperature entry and push the knob
   3. Turn the knob to the right to scroll down to the Nozzle entry and push the knob
   4. Turn the knob to the right until the correct temperature is displayed and push the knob
   5. Wait until the nozzle temperature reaches the temperature you set
2. Retract the extruder by 100mm
   1. Push the knob on the display
   2. Turn the knob to the right to scroll down to the Motion entry and push the knob
   3. Turn the knob to the right to scroll down to the Move Axis entry and push the knob
   4. Turn the knob to the right to scroll down to the Extruder entry and push the knob
   5. Turn the knob to the right to scroll down to the Move 10mm entry and push the knob
   6. Turn the knob to the left until it reaches -100 and push the knob
   7. Wait for the extruder motor to stop turning
3. Push up on the lever of the extruder and pull the remaining filament out of the tube
4. Wrap the free end of the filament around the spool and put it away
5. Set the hot-end temperature to the printing temperature of the new material
   1. Push the knob on the display
   2. Turn the knob to the right to scroll down to the Temperature entry and push the knob
   3. Turn the knob to the right to scroll down to the Nozzle entry and push the knob
   4. Turn the knob to the right until the correct temperature is displayed and push the knob
6. Verify that the end of the new filament is clean
   1. If it is not, use the cutters to cut a small section off of the end to get a clean end
      
      

      If you cut the filament at an angle it will be easier to push into the extruder

7. Put the new spool on the machine
8. Push up on the lever of the extruder and push the end of the new filament into the tube
9. Hold the lever of the extruder up and push the filament in until it stops
10. Verify that the hot-end temperature is at the correct temperature
11. Extend the extruder until you see material come out of the end of the nozzle
    1. Push the knob on the display
    2. Turn the knob to the right to scroll down to the Motion entry and push the knob
    3. Turn the knob to the right to scroll down to the Move Axis entry and push the knob
    4. Turn the knob to the right to scroll down to the Extruder entry and push the knob
    5. Turn the knob to the right to scroll down to the Move 10mm entry and push the knob
    6. Turn the knob to the right until it reaches +50
    7. Wait for the extruder motor to stop turning
    8. If new filament hasn't started coming out of the nozzle then turn the knob to the right until it does
    9. Press the knob
12. Set the hot-end temperature to 0
    1. Turn the knob to the left to scroll up to the Move Axis entry and push the knob
    2. Turn the knob to the left to scroll up to the Motion entry and push the knob
    3. Turn the knob to the left to scroll up to the Main entry and push the knob
    4. Turn the knob to the right to scroll down to the Temperature entry and push the knob
    5. Turn the knob to the right to scroll down to the Nozzle entry and push the knob
    6. Turn the knob to the left until the temperature reads 0 and push the knob

After changing the filament you can run your design or turn off the machine
