OmniaDrop V2.1 extruder on XChange - Fast TPU and more

In order to print flexible filament efficiently I have a whole 3D printer modified for the purpose. In this video, I test the OmniaDrop V2.1 extruder/hot end, which is designed to print TPU at higher feedrates, along with regular filaments. After testing I’ve concluded that it works as advertised. Thanks to the XChange system, I can switch between it and my other extruders in seconds.

The OmniaDrop V2.1 was supplied free of charge by DropEffect for the purposes of making this video in accordance with my review policy. The latest XChange system was also provided free of charge with no expectations of a video. This was to show me the improvements that have been made since the prototypes and allow me to assist with the development of future automatic tool changing functionality. All opinions expressed on both products are my own.

Please let it be clear the only reason this didn’t fit was because of my custom carriage mounted BLtouch.
