Cables for Bambu Lab 3D printers

The cables in FDM 3D printers may require replacement due to wear from continuous movement, exposure to heat generated by components such as heated beds, improper handling causing internal damage, possible electrical interference affecting signal integrity, connector wear, upgrades or modifications to the printer, and the presence of defective cables or low-quality materials. Regular inspection and timely replacement of damaged cables are crucial to maintain printer reliability and performance over time.

These cables for Bambu Lab X1 series 3D printers are original spare parts and come in various types:

• TH V9 Board FPC Cable: establishes a connection between the TH mainboard and the interface board.
• MC AP Cable Pack (2-in-1): these two cables connect the AP board and the MC board of X1 series printers, facilitating power supply from MC to AP and enabling data interaction between them.
• The AMS Cable Pack (5-in-1) is designed for internal communication of the AMS system. Includes:
  • RFID board connection cable
  • Speed measurement board connection cable
  • Filament selection board connection cable
  • Power supply connection cable
  • 485 bus connection cable
• The Printer Cable Pack (4-in-1) is an internal cable set for Bambu Lab X1 and P1 Series printers. Includes:
  • Communication cable between the AC board and the MC board
  • MC board power cable
  • Heated bed V3 power cable
  • Connection cable between MC board and AMS interface board
• The LOGO LED Cable connects the front cover of the print head with the extruder board in Bambu Lab X1 Series printers. This cable is exclusive to the X1 series and allows the logo on the print head to illuminate, adding an aesthetic touch to the printer.
• The AMS Lite 4-pin Cable is used to connect the A1 Mini main unit with the AMS Lite device.
• The 4-pin bus Cable (not to be confused with the previous one) is used to connect the printer to the Buffer or Hub.
• The Induction Hotend Rack Cables Pack includes two essential cables for the Vortek system:
  • A cable integrating communication and power between the hotend rack control board and the MC board, ensuring stable signal transmission and power supply.
  • A cable connecting the control board with the hotend closure actuator, responsible for transmitting the internal mechanism status signal.
• The Toolhead to MC Board Cable - H2D/H2C connects to the MC board and extends to the buffer area, linking with the cable integrated into the toolhead board.
• The Printer Cable Pack (7-in-1) includes: MC-AC cable, Hall board emergency stop button detection cable, Hall sensor cable for left side panel, Hall sensor cable for right side panel, MC board power cable, 4-pin interface board cable, and buffer cable.

Replacement Instructions

Detailed instructions on how to replace these cables in X1 series 3D printers can be found in the Bambu Lab Wiki for the FPC cable and also for the MC AP cables.

Before performing maintenance on the printer, it is crucial to turn off the printer and disconnect it from the power supply to avoid possible short circuits that could cause electronic damage and safety hazards.
