Beacon H
$79.99 – $88.99
Eddy current displacement sensor for homing and surface scanning in 3D printers.
Works exclusively with Klipper. Comes fully assembled and includes a USB cable.
WARNING: Requires a conductive surface or substrate on printer bed to work. Bed stacks that include oversized fixed magnets are not recommended and may not work with Beacon.
Pre-Order Now: Ships end of December 2023
Eddy current surface scanner for 3D printers:
- Native displacement output – no z motion necessary for sensing
- Scan mode mesh – dense grid sampling in a matter of seconds
- Low thermal drift – minimized by design, active compensation for everything else
Printer Compatibility:
- Firmware: Klipper
- Connection: USB to Single Board Computer
- Bed: Conductive surface or substrate, 400um or thicker. Bare steel, WHAM BAM, PEI coated or laminated steel, etc. Use with beds employing large or oversized fixed magnets is not recommended.
Includes:
- 1x Custom USB cable (6ft free or 10.5ft for an additional fee)
- 1x Beacon board (main PCB, sensing PCB, headers, cable connector)
Variations – this is important for mounting Beacon to your tool head appropriately:
- Normal: main PCB and sensing PCB are assembled flat
- Low Profile: main PCB and sensing PCB are assembled flat (as well as the cable connector)
Warranty:
- 60-day standard warranty
