====== Prusa i3 Mk2.5 =====


on loan

=== Status ====

  * 2019-10-28:
    * works and prints beautifully without problems or issues or things that needed fixing (tested with PrusaSlicer and SD-Card)
    * filament sensor PAT9125 does not work and needs to be disabled in firmware
      * either sensor is dead or not supported in MK2.5 Firmware, since prusa only sells this type for MK3
