We present a Legio3D extruder mod. To assist with machine calibration, we've incorporated a BL-Touch. While you can integrate this mod using the official firmware and board, we installed it on a Legio equipped with a Ramps board and an Arduino, replacing the original LionHeart board. Therefore, compatibility with the manufacturer's latest firmware version isn't guaranteed.

Given its design, printing the part in ASA or ABS is recommended for superior results. Combining the BL-Touch support and layer fan in a single piece enhances its ability to withstand the extruder's high temperatures.
