I have developed this sensor/splitter for permanent lifting of the filament using Pico MMU. It helps synchronize the extruder motor and Pico using software developed for Bilay.
This sensor is not for beginners, and the perfect version may not come out on the first try. It will also require some non-standard components.
BOM:
- PTFE tube OD6*ID4 for bushings
- PTFE tube OD4*ID2.5/3 for the outgoing tube
- PTFE tube OD4*ID2/2.5/3 (recomended 3) for incoming tubes
- OD2.5*ID~2 steel tube. I used a 10G piercing needle
- Glue for gluing steel tube
- Micro switch type KW10-Z0
- 1x M3*10 screw
- 2x M3*5 screw
- 3x M2*12 screw
- Any plastic suitable for temperature conditions of use
In order for the sensor to work correctly, several unobvious design decisions were made:
1) At the printing stage, 6*4 PTFE tube bushings are embedded in the sensor housing (a pause was set in the slicer on the desired layer).
2) In order for the plastic to pass through the splitter in 10/10 attempts, a 2.5*2 steel tube was added. It is glued into the case after printing
3) To hold the 4 PTFE tubes in the splitter, insert them into the mount and treat them with a sharp stationery knife as in the photo. I also screwed in the M2*12 screw between the PTFE tubes (as seen in the photo)
4) To hold the part (which presses the end cap) on the PTFE tube, it must be cut according to the printed template. Insert the tube into the part and secure it with a piece of filament.
In the final, you should have the following construction:
