Galileo 2 (G2E) Filament runout sensor (UPDATED) [Filametrix and ERCF compatible]

Galileo2 (G2E) with filament runout sensor.
 

- ECAS-Fitting compatible.
- Step file included.
- No change in overall G2E dimensions

BOM:
 

• 1x Omron D2F microswitch
• 1x 5mm steel ball bearing
• (optional) 2x M2x8 self tapping screws
   (You might get away with M2x10 and some shims, I did.)

Assembly instructions:

1. Carefully bend the pins of the microswitch flat (but not fully against the housing)
2. solder wires to the outermost pins of the microswitch
3. insert a 5mm steel ball into the hole
4. insert the switch into its mounting place
   you may need to depress the microswitch while inserting.
5. IMPORTANT STEP: slide in some filament and check if the switch actually got depressed.
   If not: Flow some solder on the “backside” of the switch connectors, tightening the fit.
      This way, you can easily tighten the fit if the tolerances are too large on your print.
6. (Optional): Secure the microswitch with some glue or screws.
7. Update your Klipper config.

BE WARNED! This works on my Voron 350 with an SKR Octopus board. and a Revo Voron Hotend. If you use it, do so at your own risk, and update what's needed so it runs on your printer. I will not be held accountable for any damage to your printer caused by your own actions.

Changelog: 

- 02.04.24
    G2E was officially released.
    I remodeled the file based on the officially released G2E Cad. (V2)

- 03.04.24
    Added a Filametrix filament cutter compatible version

• Filametrix version needs a bowden tube before the heatset, cut to length, insert and check, lock in place with heatset
• Yes, ERCF works absolutely beautiful with just a filament entry sensor in the toolhead.
  I didn't see a second sensor that useful as we mostly print without an MMU anyway, so why the overhead?
