TES Turtle Neck 2 Remastered Filament Buffer with Onboard Klipper MCU (Pre-Order)

Details

The Turtle Neck 2, redone. Same footprint and mounting as the original TN2, but the electronics are completely redesigned: the Klipper MCU now sits on the buffer itself, so the wiring to your filament changer or autoloader gets a lot cleaner. The buffer position comes from a Compensator linear Hall sensor array instead of switches, which gives AFC a true linear position with known endpoints, no calibration needed.

What's on the board

• Onboard Klipper MCU, USB by default, optional 24 V power and CAN bus
• Built-in Compensator linear buffer with dual raw Hall signals
• Runs up to 6 Compensator buffers from this one MCU
• 5 extra ADC/endstop-capable inputs
• NeoPixel/RGB addressable LED output
• Modular inlet for buffer-mounted filament hubs

Pre-order. I'm bringing this in from Pulsar3D in the US. They're waiting on their own batch, so I can't give a ship date yet. As soon as it lands in the Netherlands it goes out to you, and you pay no import fees or customs on top.
