¶ Cable Chain
The cable chain is used to connect the toolhead to the rear side of the printer. The PTFE tube, USB-C cable, and MC-TH communication/power cable are all installed within the cable chain.
The cable chain includes the following:
-
Cable chain (pre-installed with two clips) * 1
-
Cable chain bracket/base * 1
¶ When to use
-
The cable chain is broken.
-
The cable chain base is damaged and cannot be secured.
¶ Tools and materials needed
New cable chain
The replacement process for the cable chain does not involve any screws.
¶ Safety Warning
IMPORTANT!
It's crucial to power off the printer before conducting any maintenance work, including work on the printer's electronics and tool head wires. Performing tasks with the printer on can result in a short circuit, leading to electronic damage and safety hazards.
During maintenance or troubleshooting, you may need to disassemble parts, including the hotend. This exposes wires and electrical components that could short circuit if they contact each other, other metal, or electronic components while the printer is still on. This can result in damage to the printer's electronics and additional issues.
Therefore, it's crucial to turn off the printer and disconnect it from the power source before conducting any maintenance. This prevents short circuits or damage to the printer's electronics, ensuring safe and effective maintenance. For any concerns or questions about following this guide, we recommend submitting a technical ticket regarding your issue and we will do our best to respond promptly and provide the assistance you need.
¶ Replace the Cable Chain
¶ Remove the Cable Chain
¶ Step 1: Remove the PTFE tube
To facilitate the subsequent removal/installation of the cable chain, you can first disconnect the PTFE tube from the buffer.
Push the buffer slider to the far right, then press the pneumatic connector and disconnect the two PTFE tubes from the buffer.
¶ Step 2: Remove the Clips
Unfasten the clips installed on the cable chain and remove both clips.
After removing the clips, the PTFE tube can remain on the clips. The following images are for demonstration purposes only.
¶ Step 3: Remove the Cable Chain
- First, disconnect the side of the cable chain connected to the cable chain base, and partially pull out the USB-C cable and MC-TH cable from the cable chain.
- Remove the tail of the cable chain from the upper cover, then completely remove the USB-C cable and MC-TH cable from the cable chain to fully detach the cable chain.
¶ Install the Cable Chain
¶ Step 1: Install the Cable Chain
- First, insert the USB-C cable and MC-TH cable into the cable chain (the side near the base can be left uninstalled temporarily), then connect the cable chain to the upper cover.
Note the orientation: the end with round holes connects to the upper cover, and the end with protrusions connects to the cable chain bracket.
- With the closed side of the cable chain facing outward, insert the first section of the cable chain into the bracket clip, then push the cable chain forward until it is fully secured with the upper frame clip.
- Insert the remaining USB-C cable and MC-TH cable into the cable chain and connect the cable chain to the base.
¶ Step 2: Install the Cable Chain Clips
Install the two clips on the 8th and 18th sections of the cable chain (counting from the base side). Refer to the images below to reattach the clips to the cable chain.
During clip removal, the PTFE tube remains on the clips. The following images are for demonstration purposes only.
¶ Step 3: Reconnect the PTFE Tube
Reconnect the PTFE tube to the buffer.
¶ Replace the Cable Chain Base
¶ Remove the Cable Chain Base
- Disconnect the cable chain from the base and partially pull out the USB-C data cable and MC-TH cable from the cable chain to facilitate removal of the base.
- Tilt the base outward to remove it from the toolhead mid frame.
Note: The bottom clips of the base may break during removal.
¶ Install the Cable Chain Base
- First, insert the USB-C cable and MC-TH cable into the base, then snap the cable chain into the toolhead mid frame.
- Insert the USB-C cable and MC-TH cable into the cable chain, then connect the cable chain to the base.
¶ Verify the Functionality
Ensure that all cables and PTFE tubes are securely attached and the cable chain is not loose.
