2. Connect the screen cable: Pay attention to the direction shown in the figure and press to connect.

2.1.2 Install Spool Holder and PTFE Tube

1. First, remove the two material rack screws from the back panel.
   Then, align the material rack with the holes on the back of the machine and secure it with the two screws.
2. Connect the PTFE tube: As shown in the picture,connect both ends of the PTFE tube to the pneumatic fittings on the material rack and the machine.

2.3 Connecting CFS

Users who have not purchased CFS can skip this step.

Yellow is the PTFE tube.
Green is the 485 cable.

2.3.1 Install the filament buffer

1. Install the filament buffer on the back of the printer and tighten it with two buffer screws; pay attention to the direction of the buffer, do not install it in a wrong direction.

2.3.2 Connect the PTFE tube and 485 cable

• The longer PTFE tube connects the CFS five-way connector to the buffer.
  The shorter PTFE tube connects the CFS buffer to the printer.
• The shorter 485 communication wire connects the CFS to the buffer.
  The longer 485 communication wire connects the CFS to the printer.

1. Connect CFS hub outlet and buffer: insert one end of the longer PTFE tube into the CFS hub outlet (position a); insert the other end into the buffer (position b, any of the four holes).
2. Connect the buffer to the printer following steps A, B, and C.
3. Connect CFS and buffer Creality 485 cable: Note that the elbow is inserted into the buffer position c, and the straight head is inserted into the CFS position d (either of the two 485 sockets of CFS).
4. Connect the CFS to the printer using the 485 communication wire: This cable has 6-pin straight connectors on both ends with no specific orientation.
   Insert one end into position E on the CFS and the other end into position F on the machine interface.

2.4 Connecting Multiple CFS

Users who have not purchased CFS can skip this step.
Green is the 485 cable.
Yellow is the PTFE tube.

2.5 Power-on Guide

1. Follow on-screen prompts to complete the boot program (about 30 minutes);
2. Loud sounds during vibration optimization are normal.

The current interface is for reference only. Please refer to the latest software/ firmware UI on the official website for updates.

Product Usage

3.1 User Interface

The left side is the navigation bar :

1. Home: In idle state, you can view the temperature of each part of the machine; during printing, you can view the model printing progress and other information on this interface;
2. Adjustment page: On this page, you can operate the machine to move, load filaments, etc.;2
3. File page: On this page, you can choose to print files and operate printing; 3
4. Function setting page: You can set network, camera and other functions; you can also view machine information;4
5. Help page: You can export logs or view machine wiki.5

The current interface is for reference only. Please refer to the latest software/firmware UI on the official website for updates.

3.2 Loading Filament From Spool Holder

1. If the filaments support RFID recognition, align the chip on the filaments with the RFID recognition position of the machine body to scan the filaments, and the filament information can be automatically set;
2. Hang the filament on the spool holder；
3. Thread the filaments into the Teflon tube and push gently until they cannot be pushed;
4. If the filaments do not support RFID recognition, you need to manually click on the screen to set the filament information: Adjustment page → Filaments → Edit (as shown below the material rack), set the filament brand-type-name-color respectively, and finally click OK to save the settings;
5. Extrude: Push the filament gently by hand, and click “Extrude” on the filament interface. The machine will automatically set the current filament temperature, and will automatically extrude the filament after the heating is completed;
6. Retract: A. Click Retract on the filament management page, and the extruder will automatically move to the left front to cut off the filament for retraction;
   B. Wait for the retraction to end, and extract the filament from the Teflon tube behind the machine.

During extruding, you can observe whether there is filament flowing out of the nozzle. If no flow-out is observed, you can gently push the filament toward the extruder at the Teflon tube behind the machine, and then click “Extrude” again.
The current interface is for reference only. Please refer to the latest software/firmware UI on the official website for updates.

3.3 Loading Filament From CFS

To avoid filament spool getting stuck, do not use cardboard spool with untreated edges or cardboard spool that are deformed as a whole;

a is the Refresh RFID button, which can be used to read filament. If the reading is successful, the remaining filament and filament color will be displayed. If the reading fails, the filament editing button will be displayed, and the filament will be displayed as “?”;
b is the empty slot state, displayed as “/”, and editing is not supported;
c means that the RFID filament is read, the eye icon is for viewing filament information, RFID filament only support viewing;
d if this is RFID and you want to use non-RFID next time, click the pre-loading button, wait for the reading to complete, and then click the filament editing button; is ordinary filament, which support editing;
e is the state where RFID is not read, the filament display “?”. At this time, you need to click the edit button to manually edit the filament information;
f is the CFS humidity status. Green means the humidity is appropriate, orange means the humidity is slightly higher, and red means the humidity is very high. The desiccant may need to be replaced.

1. Introduction to the filament management interface: The filament management page is divided into two parts: the spool holder [left] and the CFS [right]. The code above the filament in the CFS, such as 1A, indicates the slot number;Loading filament: Put the filament into the CFS, align the filament head with the Teflon tube of corresponding silo, push it in gently, and let go after feeling the pulling force. The filament will be automatically loaded.Unloading filament: First, make sure that the filament is not in the extruder, in this case, just pick up the filament and pull it out; if it is in the extruder, click the Retract button first, wait for the filament to return to the CFS, and then take out the filament.
2. Load/unload filament.

First Use

4.1 Filament Setup

1. Put in filament and wait for tightening (RFID filament does not need to be edited, in case of non-RFID filament, “?” will be displayed after reading, and filament needs to be edited manually);
   The current interface is for reference only. Please refer to the latest software/firmware UI on the official website for updates.
2. Check whether the filament information displayed on the screen corresponds to the filament in CFS.

4.2 Print

• The area a is the color and type of the material contained in the print file. For example, the green background PLA in the figure indicates that green PLA is required;
• The area b is the state after the mapping of the print file to the filament bin is completed. For example, there is no green PLA in the filament bin, and the blue PLA is automatically selected;
• When the mapping fails, ‘–‘ will be displayed, and the user needs to manually select the material;
• Enabling CFS means printing with CFS filament, otherwise the material rack filament will be used for printing, and the multi-color file will be regarded as a single-color file;
• Checking print calibration will perform automatic leveling, AI calibration and other functions.

1. Click the file on the screen, confirm the filament mapping status, and click Print; The current interface is for reference only. Please refer to the latest software/firmware UI on the official website for updates.
