Eddy Current Surface Scanner for 3D Printers:

Bed mesh - dense grid sampling in seconds
Low thermal drift – minimized through design, active compensation for everything else

RevH:

High temperature range for accelerometer - measurements up to 100°C, standby up to 115°C

Printer Compatibility:

Firmware: Klipper
Connection: USB to Single Board Computer, such as Raspberry PI
Bed: Conductive surface or substrate, 400 µm or thicker. Bare steel, WHAM BAM, PEI-coated or laminated steel, etc. Use with beds that use large or oversized magnets is not recommended.

Includes:

1x Custom USB cable
1x Beacon PCB

Variants

Normal : main PCB and readout PCB are mounted flat
Low profile: main PCB and readout PCB are mounted flat (as well as cable connector)

Warranty:

Using a BTT Pi or BTT Manta board with Beacon without an inline hub voids the warranty.
