SB2209 Large Gear Clockwork2 HGX (and FilamATrix alpha version)

A small remix of Large Gear Clockwork2 HGX that allows you to use SB2209 RP2040. Also available in Meowburner version. There may be minor errors in the model. 

SB2209 CAN (stm version)  not compatible 

Based on user feedback, support for the STM version is being discontinued due to conflict between the gear and a component on the board.

Important note.

A version compatible with hgx v2 is currently in the design and early testing phases; hgx v2 will allow for the use of the SB2209 CAN (STM) version, as it has smaller gears, eliminating the problem of collision with a component on the board

Fan cover BOM

• 4x M3x12 BHCS - DON’T OVER-TIGHTEN The bolts are screwed directly into the plastic.

• 1x 2510 axial fan

Important!

Installation of SB2209 RP2040 may also require shortening 2 pins from the TH0 connector (on the other side of the board), as they may interfere with the rotation of the gear).

Version 1.3-FilamATrix w/ filament sensor - alpha
 

Still untested version with filament cutter, but now with filament sensor. 

Many thanks to @Shoikan for testing and providing feedback for the FilamAtrix version.

This version requires trimming two corners of the switch (approximately 0.5 mm at a 45-degree angle). due to limited space for the sensor.

example image how to trim it roughly

Filament sensor BOM

• 1x D2F switch 

• 2x M2x10 self tap screw - same as in Voron

• 1x 5.5mm steel ball-bearing

Version 1.2-FilamATrix w/o filament sensor - alpha

Untested version with filament cutter that should be compatible with hotends from the FilamATrix project.
Based on FilamATrix G2E version. 

Required printed parts:

• [a]_latch_filamatrix

• Filametrix Arm-hgx

• Knife_holder

• main_body_HGX_filamatrix / main_body_HGX_meow_filamatrix

Version with one or maybe two filament sensors is currently being developed. It will require a custom PCB .

Version 1.2 

Improved gear alignment and tolerances for easier filament loading - now available
Version 1.2 requires printing a new main body and additionally guidler a and b
