Wired path changers

The same split as inductive/pogo, but the heater and thermistor stay on a wire back to the board instead of crossing a contact.

Pros

• A crimped or soldered joint is more predictable than a contact.
• No pin wear.
• No custom electronics.
• Can be preheated.

Cons

• Without a dock fan preheating could cause heat creep.
• More wiring, requires redundant mosfets and thermistor pins.
• Gears have to open and re-engage filament path every time.
• More challenging for flexible materials than conventional toolchangers.
• Extruder places variable load on kinematic coupling.
