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 RevH: High Temp Accelerometer – measurement up to 100C, standby up to 115C 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) We are currently only stocking "Normal" Beacon, but may stock low profile in the future Warranty: 30-day standard warranty (following the date of delivery to you) Using a BTT Pi or BTT Manta board with the Beacon without an inline hub voids the warranty
