Automatic system to disable AMS when external filament is used via Y-splitter. You can use as a filament sensor too.

Very useful especially on P1P/P1S models as they do not allow you to not use AMS from the screen.

Hot to print:

• 0.08 mm layer hieght
• PLA
• No support (you have to remove the blue part in the following picture)

What you need:

1. PC4-M10 Straight Pneumatic Fitting
2. Microswitch (endstop) curved handle
3. AMS 4-pin cable
4. Basic soldering skills

How to assembly:

1. Remove the external insulation of the original cable, exposing the 4 wires inside for approximately 2 cm.
2. Cut the red wire (+24v) and extend the two ends with a bipolar cable.
3. Insulate everything and close with insulating sheath or tape.
4. Pass the two-pole cable through the hole in the printed part.
5. Connect the other two ends to the C and NC pins (the first and third, as seen in the figure) of the microswitch.
6. Insert the microswitch inside and close the clip.
7. Fit the preumatic connector at the ends and connect to the PTFE paying attention to the direction of the arrow.

P.S.: A version without the inlet connector is available
