Bambu Lab Heatbed Signal Cable – X1 / P1 Series (CAB016)

Original Bambu Lab CAB016 heatbed signal cable for X1 and P1 series printers. This 6-pin cable connects the heatbed sensor to the printer's main board and ensures accurate transmission of temperature and leveling signals, which are crucial for a stable first layer and high-quality printing.

Key Features

• Original Bambu Lab spare part – model CAB016
• Designed for X1 and P1 series (P1P, P1S, X1C, X1E)
• 6-pin signal cable for:
  • heatbed temperature measurement
  • position and load detection for automatic leveling (auto-levelling)
• Connectors: double-sided 6-pin 1.25 mm MX (Molex style)
• Cable length: 555 ± 5 mm – exactly matches the original routing in the printer
• Durable insulation for operation near the heatbed
• Simple "plug & play" replacement – no soldering required

When to Replace the Cable

Replacement of the heatbed signal cable is particularly suitable if:

• the printer reports errors such as weak/no heatbed sensor signal
• there is incorrect heatbed temperature measurement (fluctuations, unrealistic values)
• auto-levelling fails or is unstable
• there are visible cracks, breaks, or damaged insulation on the original cable

Regular use and bending during bed movement can lead to cable material fatigue over time. Replacing it with a new, original part will help restore measurement reliability and first-layer consistency.

Compatibility

This cable is intended for the following Bambu Lab 3D printers:

• Bambu Lab P1P
• Bambu Lab P1S
• Bambu Lab X1 Carbon (X1C)
• Bambu Lab X1E

In summary: X1 Series & P1 Series.

Technical Specifications

Note: The cable transmits heatbed sensor signals, it is not a power cable for bed heating.

Installation and Use

1. Turn off the printer and disconnect it from the power supply.
2. Disassemble the heatbed according to the manufacturer's recommended procedure.
3. Disconnect the original signal cable from the connectors on the bed sensor and the main board.
4. Plug in the new CAB016 cable into the same connectors (maintain correct orientation).
5. Check the cable routing so it is not pinched or excessively bent.
6. Reassemble the heatbed and turn on the printer.

After replacement, we recommend running a bed calibration and checking the behavior of the temperature sensor in the Bambu Studio software.

Who the Product is For

• For Bambu Lab X1/P1 printer users who want to have essential spare parts in stock.
• For those dealing with temperature measurement or auto-levelling issues and needing a reliable, original solution.

By using an original Bambu Lab signal cable, you minimize the risk of errors during printing caused by incorrect signals from the heatbed and ensure stable and repeatable printing results.
