Tiêu đề Máy đùn cho Prusa MK3 với E3D Revo Micro và Orbiter 20 Tóm

This is my new extruder for Prusa MK3 featuring E3D's Revo Micro and the new Orbiter 2.0. For download I added the complete assembly in step-format. Free to further develop these data. The Orbiter needs different settings which are all described in the documents coming with the Orbiter. You'll need to adapt the Orbiter cable plug as shown. I took a spare Einsy cable, cut off the plug with some 50mm cable rest, attached (soldered) 5x0.6mm wire to the ends and shrinked the connection. I used a 25x25x6mm hotend-fan with a 3-wire lead which prevents problems with the Prusa firmware. It's a SUNON KD0502PEB1-8 which is quite hard to come by. Update: 1. KD0502PEB2-8 (25x25x6.8mm) can be used as replacement. The airflow is a little bit less but it does the job without problems. 2. I did an update on the Pinda attachment using 2 M2.5 screws. If anyone is interested please ask. (endUpdate) E3D ships a 2-wire hotend-fan (20x20x10mm) with the Revo Micro hotend. For anyone looking for another fan: The hotend-fan needs a airflow volume of 1.9 CFM. For the 3 main structural parts (x-carriage/x-carriage-back/adapter RM-Orbiter 2.0) I used ColorFabb PA-CF because you need optimal stiffness here. For the M12x1.5 thread in the Orbiter/Revo Micro-adapter it's advisable (at least for PA-CF) to use a cylindrical speed modifier area (eSlicer) around the thread to reduce the speed locally to 12 mm/s.

Layer height for PA-CF: 0.2mm/0.4mm nozzle(X). Other filaments: Extrudr GreenTEC PRO (print fan shroud, hotend fan holder, Pinda mount), PLA (remaining 2 parts). 2 parts with 0.25 nozzle/0.1mm layer height: hotend fan holder, Pinda mount. Remaining parts with 0.4mm nozzle/0.15mm layer height . Supports only for print fan shroud (3 air exits), hotend fan holder (arc) and My pinda mount2 (Petg, extensive supports, difficult postprocessing :-( Update 02.12.2023: Pinda-position corrected (gregsaun/prusa_i3_bear_upgrade#142). Pinda-adjustment improved (https://www.printables.com/de/model/227763-superpinda-precision-adjuster-for-prusa-i3-mk3s). Tip: Plastic is not metal. Don't overtighten your screws and regularly check and fasten them if necessary. Best check before every print session. If anyone needs more information please ask me.
