Anet A6/A8 Bed Level Thumbwheel Upgrade

Manual bed leveling the Anet A6/A8 is a little awkward and could be made a lot easier. There are some good solutions on the net - I took the best, made modifications and kept it simple.

This solution allows you to cover the entire hotbed with a build plate as you no longer need access to adjusting bolts from the build surface. All adjustment is done with the thumbwheels!

All metal! at the hot end - this allows you to heat up the bed for ABS, Nylon and other high temperature filaments without melting your bed level adjustment.

From the kit you will need:

• 4x Springs
• 4x Screw M3*30mm

Additional you will need:

• 8x M3 Nut (Optional: Use self-locking nuts for thumbwheels)
• 4x Steel/nylon M3 washer (Optional: I used large, but regular is OK)
• 4x Spring Cap (Print model)
• 4x Thumbwheel (Print model)
• A 3mm or 1/8" drill for stripping M3 thread 

Note: To make this bed level upgrade, you need to strip the M3 thread in the Y carriage aluminum frame. This can not be reversed.

If your heat bed has copper traces under the washers, I recommend using nylon washers instead of metal to protect the heating element (eBay Search).

Just follow the photos to assemble.The M3 nuts is a tight fit in the thumbwheels to prevent them falling out.

Tip: Print all parts at once, this will help the small parts cool between layers and give a better result.
