6/6/2020: Added passthrough body to sync up with bear 1.0.0 release
11/2/2019: Someone pointed out that I didn't have the source and step files, my oligopolies this was an oveight. Thanks joseph.m for pointing that out.
7/5/2019: Everything is synced up with the bear 0.7.0 extruder release, I also updated the FS cover to allow usage of the M2 screw that comes with the MMU2S upgrade kit. The FS cover and FS cover cap were changed to accommodate this.
6/7/2019: Added latest parts that are compatible with the latest bear MK3S extruder design (dev branch). These parts all have a prefix of "bear_dev_190604"
5/25/2019: Updated passthrough body to sync with latest bear dev design, per Greg's notes should improve heatsink cooling efficiency. Also improved bridging over the 3d printed filament path above gea.
5/23/2019: For those 100% committed to the cause, I have added a passthrough body, this guts out all the mk3s seor parts at the top of the body and allows you to feed your MMU2S feed tube almost all the way down to the gea (bear_dev_passthrough_body_v3.stl). If you use this you do not need the plug parts.
5/17/2019: Updated arm to allow more clearance around bowden coupler stack (Seor_Arm_v4.stl), updated cover to have taller stack (fs_cover_v4.stl), this helps prevent from bumping the arm when ucrewing a bowden coupler. Added a new ball bearing plug with tighter tolerances to prevent filament from hanging up on edges of walls (Ball_Bearing_Plug_01_v3.stl) I recommend printing the arm and plug at .1mm layer heights.
5/7/2019 Update: Updated the cover to allow PTFE to go all the way through and butt up agait the body.
4/26/2019 Update: Updated the seor arm to beef it up a little near the tip, I recommend pringing this at .10mm layer heights, or .15mm at least
4/25/2019 Update: I have uploaded new files that are compatible with the new bear extruder DEV branch. These should also work with the supplied molex connector. The seor is shifted forward and requires the curved arm. Print the arm as it is oriented when loaded into your slicer. I recommend a brim. I have not yet tested the new design but hope to itall it shortly.
This is an adaptation of the Prusa MMU2S door seing mechanism.
You will need the parts that came with the MMU2S mod (IR seor, the M2 Screw), you will not be using the magnets or the steel ball.
You will need 2 extra M3x10 screws and 1 of the thin square nuts.
The arm is removable and adjustable.
You will want to update your Single extruder multimaterial paramete in Prusa Slicer. Here are the settings that I am using.
Cooling tube position: 35
Cooling tube length: 15
Filament perking position: 85
Extra loading distance: -16
