MedusaHC V0.2 – Budget Hotend Toolchanger

MedusaHC is an open-source budget toolchanger that swaps only the hotend assembly, including the heater, thermistor and fan. It was developed as an add-on for Duender and can also be adapted to other DIY CoreXY printers.

V0.2 BETA

This release supports two dock layouts:

• V-Front — the tools are installed in front of the print area. This provides more available space and can be convenient for Voron-style and other CoreXY machines.

• V-Back — the tools are installed behind the print area, closer to the XY motors. This reduces the influence of belt elasticity during docking and keeps the front of the printer open and easy to observe.

The supplied configuration is prepared for four tools. The full STEP assembly demonstrates five tools in the front layout and four tools in the rear layout.
