If you have ever used an induction probe for bed leveling, you probably already know just how finicky it can be. I have always generally hated the amount of extra work that is required when printing with a machine that uses an induction probe. The Elegoo Orangestorm giga uses an inductive probe and it was really annoying to deal with. So I designed Giga Tap: its an optical probe which moves on the printer’s Z axis and gets triggered when the extruder’s nozzle is pressed against the bed of your printer. This will (theorhetically) remove the “guessing game” that is involved with leveling your bed using the paper test. You only need to do the paper test once and save that in your klipper’s configuration file. Anytime you decide to do a quick bed mesh for your print, when it asks you to provide the z-offset, just hit “confirm” since it will never change after the first time you configured your z-offset (until you change your nozzle).

Installation should be pretty simple but I will do my best to provide a step by step instruction for those who wish to make the same modifications.

Requirements:

Tools:
Soldering Iron
Wire Strippers
Super Glue

Hardware:

• OptoTap v2.4.x (must be able to run 24v!! (OptoTap v1, v2.1 and any others are KNOWN to have issues running on a 24v line! Optotap v2.4.x WORKS! The “x” is for any iteration of OptoTap 2.4 – just make sure that it is able to run 24v. Learn more here: https://github.com/VoronDesign/Voron-Tap/tree/main/OptoTap)
• 2x – 6mm x 3mm Magnet
• 7x – M3 Heat Inserts
• 2x – M3 Hex Nuts

These screw sizes are subject to change. I need to pull my build apart and measure the screws I used.

• 4x – M3 Washer x 4
• 1x – MGN 9 Rail (50mm)
• 1x – MGN 9H Carriage
• 1x – M3x14 (BHCS or SHCS is fine)
• 2x – M3x12 (BHCS or SHCS is fine)
• 7x – M3x8 (BHCS or SHCS is fine)
• 8x – M3x6 (BHCS or SHCS is fine)
• 2x – M3x6 FHCS (MUST BE MAGNETIC – i.e. made of iron or a magnetic metal – must be FHCS!)
• 4x – M3x4 (BHCS or SHCS is fine)

If you buy the Fysetc kit, you may not need any additional screws since many screws I used were from a similar kit and from the existing Elegoo Orangstorm Giga.

Print out the materials in ABS.
