Anycubic Vyper Direct Drive Extruder Mod | RE Vyperdrive

I wanted my vyper to be better and I didnt like what other people had to offer so I made my own. Here it is!

You will need an longer Stepper motor signal/power wire, 2x M3x12 screws with washers and nylock fastners and maybe some zip ties.

INSTRUCTIONS

*After installation, the extruder may be moving in reverse. This can be fixed easily by rearanging the wires in a mirror configuration on one end of the cable*

-Disconnect all power to the machine and give it a minute to chill.

-Begin by removing the cover plate on the left side of the x axis carriage.

-Disconnect the 4 wire connector to the extruder stepper motor, and remove the assembly for the extruder from the bracket and the bowden tube.

-The clear shell for the extruder should come apart and release a metal insert

- This metal insert can be replaced with the "Metal insert replacement part." This part is problematic at times due to its busy geomery and lack of bulk, so I printed like 3 just in case. 
If this part breaks, the printer can be reassembled and work as before to reprint the part.

- reassemble two halves of clear extruder and set aside.

- place the bowden tube into the coupler at the top of the hotend assembly, ensuring the end is completely flat, and completely seated.

- cut the bowden tube with around 1/4 inch or more sticking out past the depressable part of the coupler

- place the extruder above the end of the cut tubing with the 3D printd plastic insert facing down, and the release lever in the rear top. lower extruder onto the cut tubing ensuring it is 
centered and seated in the accepting hole. there will be a large gap, as the tubing is too long to allow the extruder to seat properly. measure the gap between the top of the plastic hotend 
cover, and trim that length from the bowden tube, so it can seat right on top of the plastic hotend housing without making direct contact.

- if that is done correctly, then the extruder can be set aside once again.

- remove the top two screws from the hotend cover, and cut the zip tie holding the cable for the hotend.

- install vyperdrive extruder frame/bracket, two M3 screws go through the front ziptie holes and are secured with nylock nuts and washers. the lower two holes get sandwitched 
between the metal plate and original screws. ensure all screws are started before tightening any.

- combine stepper motor to extruder, placing plug side up

- gently lower the motor and extruder into the vyperdrive frame, allowing for some lose grip as things slip into place. this may take some shifting around but it can definitely be done. 
the extruder goes back to where it sat beforehand.

- once in place, the 3 long screws for the extruder can be reinstalled.

- install motor signal/power wire

- install bowden tube coupler on the top of the extruder, insert tubing untill it stops and cut a short length to  relieve stress on incoming filament.

- zip tie untill satistied

- be sure to recalibrate the printer after this, as the behavior of the plastic is a lot different now. once calibrated it should be safe for low durometer materials like TPU.

*After installation, the extruder may be moving in reverse. This can be fixed easily by rearanging the wires in a mirror configuration on one end of the cable*

IMPORTANT!, DO NOT USE THE LOAD FILAMENT FEATURE, DO IT MANUALLY!!!

I put a little piece of filament in the runout sensor to make it happy since I don't rely on them anyways. if you guys want a way to include it please leave a comment and I'll do it
