3D printer flexible cable hub

This is a hub board for the Big Fish TT (Telematics Trigger). It should also be compatible with other extruders using 36 motors. Position the board horizontally. For Galileo extruders and similar machines, use 45° angle positioning holes; design an adapter or modify the board frame
configuration. The board includes: x limit switch *1, z limit switch *1, heating rod *1, hot end thermistor *1, motor *1, throat fan *1, blowing fans (parallel) *2, material breakage detection *1, 3D Touch *1, accelerometer *1.
Optional onboard components:
1. ADXL345 module (you can buy a ready-made module and transfer it to the board; it has been tested and works).
2. Warehouse temperature thermistor (simply solder an NTC 100k thermistor).
Notes:
1. The ribbon cable used is an LVDS ribbon cable with a clip. A 60cm cable is too long for a 235-sized TT; you can buy a shorter one. I bought a Hon Haida cable, which has a retaining strap on the back, so it won't sag too much even if it's long. However, the idler screws on the TT may interfere with the ribbon cable at certain angles, so be careful during installation.
2. The GH125 and XH connectors for the thermal sensor are connected in parallel. I originally intended to directly plug the GH125 into the thermal sensor used for the toy rod, but the thermal sensor length was slightly insufficient. Therefore, I had to extend the thermal cable to use the XH terminal. If I shortened it further, I might not need to extend it anymore.
3. The ADXL345 module can be moved to the same board or connected to a 6-pin header. However, I used a 2.0 pin header. If needed, you can modify it to a 2.54 pin header, which will be more universal.
4. Except for the parallel interfaces, all other interfaces have their own dedicated wires and do not share any wires. Therefore, the wiring does not need to be exactly as I marked. It can also be used for other purposes, such as motor wiring and heating rods. There are enough cables allocated. In actual testing, I couldn't feel any temperature change in the ribbon cable when using an 80W heating rod, so it should be sufficient.
5. The Y-limiter and RGB socket on the adapter board are not connected to the hub board; they only serve as adapters. Also, I didn't think much about the fixing method of the adapter board at the time, and the fixing position is a bit difficult to adjust. You can adjust it according to your own machine if needed.
6. Cost: Except for the NTC100K and ADXL345, the motherboard and socket can be obtained for free from LCSC. Jushuo has ribbon cable sockets, which can be purchased with coupons. I bought the ribbon cable with the clip, which cost about 17 yuan excluding shipping. Other stores also have cheaper options. This is for reference only. Attached is
