Creality CFS-C Filament Management System

2. Unboxing

This section covers the unboxing process and initial status checks.

Status Connection Diagram

The diagram illustrates the CFS-C unit and its connection points. It shows two states of the printer display:

• Printer Not Connected Display: Shows temperature readings (e.g., 210℃, 52℃, 30℃), movement control, filament status, temperature control, AI status, and spool holder information (PLA). It indicates the printer is not yet connected.
• Printer Connected Successfully: Displays similar information but confirms a successful connection.

The CFS-C Communication Module is described with indicator lights: Green light for CAN T, Blue light for RS-485++, and White light for CAN RS-. A long press of 3 seconds can switch between CAN and RS-485 modes.

3. CFS-C Usage

The CFS-C system requires connection to a printer to function.

3.1 Loading Filament From CFS

To prevent filament spool jamming, avoid using cardboard spools with untreated edges or deformed spools.

Filament Management Interface Overview

The filament management page is divided into two main areas: the spool holder (left) and the CFS unit (right). Slot numbers within the CFS are indicated by codes, such as 1A.

Interface Elements and States:

• a. Refresh RFID button: Used to read filament information. A successful read displays the remaining filament and its color. If the read fails, the filament editing button appears, and the filament type is shown as '?'.
• b. Empty slot state: Indicated by '/', meaning the slot is empty and editing is not supported.
• c. RFID filament read: An eye icon [view] allows viewing filament information. This feature is only available for RFID-tagged filament. If you wish to use non-RFID filament in this slot next, click the 'pre-loading' button, wait for the reading process to complete, and then click the filament editing button.
• d. Ordinary filament: This type of filament supports editing of its information.
• e. RFID not read: The filament displays '?'. In this state, you must click the edit button to manually input the filament information.
• f. CFS humidity status: The humidity level is indicated by color: Green signifies appropriate humidity. Orange indicates slightly higher humidity. Red indicates very high humidity, suggesting that the desiccant may need replacement.

Loading Filament:

To load filament, insert it into the CFS, align the filament head with the Teflon tube of the corresponding silo, and push it in gently. Release it after feeling the pulling force; the filament will be automatically loaded.

Unloading Filament:

First, ensure the filament is not currently in the 3D printer's extruder. If it is, click the 'Retract' button on the interface, wait for the filament to return to the CFS, and then pull it out. If the filament is not in the extruder, simply pick up the filament and pull it out.

3.2 CFS-C Connection and Usage Guide

Connection Diagram (One to Four Units)

The CFS-C system connects to a 3D printer through a series of components. An AC Power Adapter supplies power and data to the CFS-C Main units (up to four). These units are connected to a Cutter Buffer Module via PTFE tubes. The Cutter Buffer Module interfaces with Filament Detection and Structural Components, and finally connects to the 3D Printer. Communication pathways include RS-485, USB 2.0, CAN BUS, and Type-C. Data communication is facilitated through PTFE tubes.

A visual diagram shows a 1-to-4 connection setup, illustrating how multiple CFS-C units are linked to a central system and then to a 3D printer.

Safety and Servicing Instructions

For pluggable equipment, the socket-outlet shall be easily accessible.

Do not use this apparatus near water.

Clean only with a dry cloth.

Only use attachments/accessories specified by the manufacturer.

Unplug this apparatus during lightning storms or when unused for long periods of time.

Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

Internal/External Voltage Selectors: Internal or external voltage selector switches, if any, should only be reset and re-equipped with a proper plug for alternative voltage by a qualified service technician. Do not attempt to alter this yourself.

Protective Earthing Terminal: The apparatus should be connected to a mains socket outlet with a protective earthing connection.

When moving or not using the appliance, secure the power cord (e.g., wrap it with a cable tie). Be careful not to damage the power cord. Before using it again, make sure the power cord has not been damaged. If the power cord has been damaged at all, bring the unit and cord to a qualified service technician for repair or replacement as specified by the manufacturer.

Disconnect power cord before servicing.

Replace critical components only with factory parts or recommended equivalents.

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE ANY COVER. NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED SERVICE PERSONNEL ONLY.

(French translation integrated: For pluggable equipment, the power outlet must be easily accessible. Do not use this device near water. Clean only with a dry cloth. Use only attachments/accessories specified by the manufacturer. Unplug this device during thunderstorms or when not used for extended periods. Entrust all repairs to qualified personnel. Maintenance is necessary when the device has been damaged in any way, for example, if the power cord or plug is damaged, if liquid has been spilled or objects have fallen into the device, if the device has been exposed to rain or humidity, if it is not operating normally, or if it has fallen. Internal/external voltage selectors: Internal or external voltage selectors, if any, should only be reset and re-equipped with an appropriate plug for alternating voltage by a qualified service technician. Do not attempt to modify it yourself. Protective grounding terminal: The device must be connected to a power outlet with a protective grounding connection. When moving or not using the appliance, secure the power cord (e.g., wrap it with a cable tie). Be careful not to damage the power cord. Before using it again, check that the power cord has not been damaged. If the power cord has been damaged, bring the device and cord to a qualified service technician for repair or replacement as indicated by the manufacturer. Unplug the power cord before proceeding with maintenance. Replace critical components only with factory parts or recommended equivalents. ATTENTION: TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT REMOVE ANY COVER. NO USER-SERVICEABLE PARTS INSIDE. ENTRUST MAINTENANCE ONLY TO QUALIFIED PERSONNEL.)

FCC WARNING

This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) this device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation.
