Safety Warning
IMPORTANT!
It's crucial to power off the printer before performing any maintenance work on the printer and its electronics, including tool head wires, because leaving the printer on while conducting such tasks can cause a short circuit, which can lead to additional electronic damage and safety hazards.
When you perform maintenane or troubleshooting on the printer, you may be required to disassemble some parts, including the hotend. This process can expose wires and electrical components that could potentially short circuit if they come into contact with each other or with other metal or electronic components while the printer is still on. This can damage the electronics of the printer and cause further damage.
Therefore, it's essential to switch off the printer and disconnect it from the power source before doing any maintenance work. This will prevent any short circuits or damage to the printer's electronics. By doing so, you can avoid potential damage to the printer's electronic components and ensure that the maintenance work is performed safely and effectively.

Replacing the P1S Cable Chain
Replacing Only the Cable Chain Itself
Press the link at the top of the toolhead to disconnect the cable chain.
Count 2 links from the tail end of the cable chain and disconnect it from this point.
Separate the old cable chain from the cables.
Take out the new cable chain and disconnect two links from the tail end.
Install the tail end of the cable chain onto the printer.
Then install the front end of the cable chain onto the toolhead.
Install the PTFE tube.
Complete Cable Chain Installation
Use an H1.5 screwdriver to loosen the 1 screw at the back of the printer near the filament inlet.
Pull the cable chain forward to remove the cover plate.
Disconnect the cable chain from the toolhead.
Pull out the USB communication cable.
Disconnect the cover plate at the position shown in the image. The extra part is designed to protect the mainboard on the X1; it has no practical use on the P1 and you can choose whether to keep it.
Install the new cable chain onto the cover plate.
Install the cover plate and tighten the screw.
Insert the USB cable and PTFE tube into the cable chain.
Pull out the right-angle turning link from the toolhead.
Install the new right-angle link.
Install the cable chain onto the toolhead to complete the replacement.
Installing a Cable Chain on the P1P
Installing a Complete Cable Chain
Reminder:
1. To prevent step loss caused by insufficient tube length, it is advisable to replace the 530mm PTFE tube with a 550mm tube.
2. It is not recommended to immediately install a Cable Chain Assembly on P1P printers. If you want to install a Cable Chain Assembly, you may need to purchase a магазин Bambu Lab simultaneously. Both P1P version and P1S version toolhead cables can work with the cable chain. But it is recommended to use the P1S version toolhead cable to work with the cable chain due to its better resistance to bending and flexing.
Note:
- If you find that the length of the PTFE tube is insufficient, affecting the tool head movement or causing step loss during printing, you can replace it with a new PTFE tube that is 20mm longer than the original one.
- If the cable chain against the X-axis carbon rods, you can adjust the length of the USB cable and store the excess part in the MC board.
Verify the functionality
Move the tool head for a circle to confirm that the Cable Chain Assembly moves normally and there is no interference with the PTFE tube.
Calibration step after the operation
Turn on the printer and run a calibration.
