thingiverse

This text appears to be a description of modifications made to the Prusa MMU2 extruder body to improve its performance, specifically with regards to filament sensing. The author has designed and printed custom parts for the filament sensor housing, bearing, magnet, and other components. Here are the key points mentioned in the text: 1. Modifying the trap mechanism: The author mentions that when you open the trap, the sensor gets disengaged, which is a nice feature. They also added a satisfying metallic noise as the bearing moves when closing the trap. 2. Losing the iddler door: A button has been included to loose the iddler door for manual filament release. 3. Filament path modifications: The author introduced funnel shape zones in the filament's path to facilitate loading and eliminated embossments from the design. The text also mentions what is left to do: 1. Brass part of the sensor cover: The author needs to find a suitable nut or sacrifice a part from the MMU2 to create this component. 2. PTFE washers for the filament cover: They are currently using a M3 self-locking nut but may need to add PTFE washers for better performance. The text also includes updates and notes: 1. Updates to the X-Carriage part, extruder body, and sensor cover. 2. A redesign of the PRUSA extruder body to include the filament sensor housing from their design. 3. A request for feedback from users who have downloaded and printed the mod. Overall, this text appears to be a detailed description of modifications made to improve the performance of the Prusa MMU2 extruder body, specifically with regards to filament sensing.
