TitanHGXtruder NX

I have designed a new gearbox for the Titan Aero, the Titan Aero extruder has the same mounting as the Titan extruder.

I decided to adapt my AeroHGXtruderNX design to the Titan extruder with heatsink V6.

The TitanHGXtruderNX is a low-cost option for upgrading the standard Titan gearbox.

When modified, the new drive moves the nozzle axis 4.2mm away from the plane of the nema 17 motor. You must take this into account when fitting the new extruder.
- The new drive uses the original Nema 17 motor.
- We get a drive with a large gearbox that feeds HGXlite filament,
- uses an ingenious pressure lever, modelled on the @Prusa3d Nextruder, which increases the contact area between the feed wheel and the filament,
- You can seamlessly revert to the original version if you have problems installing new hardware.

Print settings, Klipper/Marlin configuration same as in AeroHGXtruderNX.

Assembly instructions - use the one from AeroHGXtruderNX.

To build the TitanHGXtruder NX you will need:

1. HGX lite kit (affiliate link)- kit parts needed for AeroXtruderNX:
- 3mm shaft (16mm length) x 2pcs to be converted into 2pcs 3x7.5mm
  Instead of the one original 3x16 shaft from the HGX kit, I recommend the following cylindrical steel pin DIN 6325 3x16 mm m6
- large filament gear with pin bearing x 1pcs
- reduction gear x 1pcs
- heat inserts (M3 x D4.5 x H5) x 4pcs 
- M3x8mm BHCS x 1pcs trimmed to M3x7mm
- M3x14mm SHCS x 2pcs trimmed to M3x11,5…12mm

2. Trianglelab brass gear 5mm/0.5M 17T (affiliate link) or other similar 5mm/0.5M17T(affiliate link).

3. Other parts needed for extruder and lever system: 

- M3x6mm SHCS x 1pcs
- M3x24mm SHCS x 3pcs
- M3x30mm SHCS x 1pcs
- Tubular spacer 4x3x8.9mm x 1pcs - I made one out of a brass tube that I have(affiliate link)

- shaft 3x7.5mm x 2pcs (I cut a free pin 3x16 from the HGX gearbox)
- 683ZZ bearings with U-groove x 2pcs (affiliate link)
- M3x20mm BHCS x 2pcs
- M3 nyloc nut x 2pcs
- spacer 6x3.1x8mm x 1pcs (affiliate link)

- M3x45mm SHCS x 2pcs trimmed to M3x31.5mm
- Spring 5x15x0.8mm x 2pcs - I made two from the long one I bought earlier(affiliate link)

******************

Assumptions according to which I designed the AeroHGXtruderNX:

• low cost,
• the new drive moves the nozzle axis 4.2mm away from the plane of the nema 17 motor,
• it must use the original Nema 17 motor,
• large HGXlite filament feeding gear,
• pressure lever modeled on the @Prusa3d Nextruder,
• trouble-free return to the original version in case of problems with the installation of the new gearbox (if you have not converted the Axis-X).

NOTES.

• The design is my idea to modify an extruder for my printer.
• This is not a certified solution dedicated to the Artillery Sidewinder X2 compliant with VDE, IEC or similar standards.
• Any modification to the printer done by yourself increases the risk of accident and fire.
• Never leave the printer on unattended.
• Use at your own risk.
