Beacon – 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 – minimised by design, active compensation for everything else
Configuration information can be found here
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. The JB3D plates we sell work perfectly!
Includes:
- 1x Custom 6ft/1.8m USB cable
- 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

H (verified owner) –
Beacon is a game changer when it comes to bed levelling. High speed scanning at a resolution of your choice makes for excellent first layer, particularly if like myself you have a less than perfect bed.
Id love to give Beacon 5 stars, but I think it’s a 4.5 because toolhead support is a bit lacking.
There is a Voron Stealthburner mount but it’s only good for a stock hotend; for my Dragon HF it’s just not long enough, and I don’t have the skills to modify the CAD myself. I ended up mounting it with spacers to bring it closer to the ideal spot, which is not great for rigidity but still functions well, probably doesn’t give the best results for resonance testing.
The install is painless and it can be up and running in a few mere minutes after the toolhead is built, just make sure it’s definitely set up and detecting before ramming the toolhead into the build plate.
