This bracket relocates the filament sensor on the Anycubic Kobra S1 combo, designed specifically to address friction and positioning limitations I encountered with other solutions. Key features include:
- Repositions the sensor straight downward, just enough to clear ACE connectors
- Features a lightweight Y-joiner that allows default filament to pass straight through
- Minimizes added distance and curvature in the filament path
- Includes a freely rotatable Y-joiner so the manual feed tube can point in any direction
- Maintains a symmetrical appearance by avoiding sideways shifts or rotation of the sensor
Materials Needed
- 2× M2.5 screws (6-10mm length)
- 2× M2.5 heat inserts
- 3× PC4-M6 pneumatic fittings
- Printed parts
Print Settings
- Layer Height: 0.2mm
- Infill: 15%
- Supports: Tree supports for joiner
- Material: PLA/PETG
Assembly
- Remove the filament sensor
- Use M2.5 heat inserts for the holes in the bottom part of the bracket
- Install the sensor in the new bracket
- Mount the bracket where the filament sensor was previously mounted
- Connect the Y-joiner and adjust to desired orientation. Make sure to push in all PTFE tubes all the way. The tube connecting the joiner to the filament sensor needs to be about 50mm in length.
Changes
- v13: Reduced hole diameter at the top to avoid hitting the PTFE tube. A slight chamfer on the inside of the top PTFE tube can also help further reduce chances of hitting it.
