Update: Dual Y motors printing @ 500mm/s

Extra motor to compensate for bed wight using de Z driver slot and sending more current, files in folder Dual Y motors upgrade, careful my printer its longer in Y than the normal size, that's how I can fit more stuff. The parts are mirrored from the one in the video so you don't have to swap cables on the new motor to reverse it.

Update: Video printing @ 350mm/s 

 

UPDATE - added Nozzle Endstop, it works with allen bit, It might need adjusting or remodeling for other allen bit pocket, uploaded step in case you need to modify.

UPDATE - Added x-carriage for the new stealthbearner and moded cable lid (if you want the upgrade but don't want to mount a new carriage you can drill the 2 top holes with a 4 mm drill bit  4mm deep and place two  threaded inserts (it worked for me on two machines do it at your own risk).

UPDATE - Added a new cable cove to keep the connectors on top of the extruder to get more x axis travel to add a z-endstop similar to what is used on the Voron 2.4 and a new part to use the same filament sensor as the mk3 with reverse bowden, a spool holder. IT ONLY WORKS WITH THE BEAR UPGRADE as its held to the the side extrusions.

Update V2, made tha strain relief stronger it was a bit to flimsy (beltlid and cable guide V2)

Mod for fitting and Voron Afterburner extruder on a Prusa i3 Mk3 and newer.
Remixed from the Voron Design Legacy X carriage and The BearExxa Bear upgrade.

Had to bring the linear rods together 5 mm to be compatible with the Legacy x carriage so yo have to redo the x axis assembly.

It uses heat inserts and m3x40, m3x35, m3x30 and m3x25 screws plus all hardware for the Voron Afterburner.

I just built it and haven't configured any firmware yet

Added step files.
