FlashForge Adventurer 5M/5M PRO HGX 1.0 Extruder

Here's new extruder for ff5adm based on HGX 1.0 gears.

More grip, more consistent extrusion, 9 gramms heavier.

What you'll need: 

HGX 1.0 extruder kit

m3x12 screw(from original extruder)

m3x14 screw

m3 heat insert

You'll have to dremel the main gear like this. Maybe 0.5mm deep.

Print in ABS front part with 0.2 (0.25) nozzle

I printed back part with 0.2 nozzle, arm with 0.6 nozzle. But i think you can print them with 0.4

How to install:

remove 3 screws from extruder, save one of them

remove right screw from a motor

remove hotend fan from old extruder, save 1 screw

remove the thumb nut from long screw that you put spring on

add heatset insert into front part of the new extruder

assemble new extruder

screw in hotend fan with one screw

install new extruder with one old screw and one m3x14 into right motor hole

Calibrate rotation distance!

And change direction pin

[extruder]
dir_pin: eboard:PB15
rotation_distance: 5.546

I added a headcap model with the convenient hole to screw the tension screw :P

Update: 

I added models of arm and spacer and front part for the version with 6701 bearing in the arm to reduce the damage on the filament. Also look in the remixes for other versions :p
