Blurolls Happy Turtle Lettuce Feeder (HTLF) by ArmoredTurtle – Multi-Color Filament Feeder for Voron 2.4, Trident, VZBot, RatRig 3D Printers – Precision Multi-Material Printing Upgrade for Cleaner Toolhead Swaps and Color Transitions

HTLF is a lane-based filament changer for Klipper designed by ArmoredTurtle. It uses a camshaft to engage the selected lane, effectively making the requested lane a direct drive extruder (no slip to contend with). The “stock build” is for a four color system, though CAD is provided should you choose to expand it further.

For best results, use with AFC Klipper Add On - a Klipper plug-in for modern multi color systems. The code for a Mainsail  integration with a clean and unobtrusive UI for AFC can be found here .. or complete a serial request in the ArmoredTurtle Discord to get access to the pre-compiled version and secure a unique number for your HTLF!
