With BEAM’s laser technology you get quick information about whether the cup is centered on the rail or not, and you can also find out, with 0.01 mm measuring accuracy, how large any deviation is. Thanks to BEAM’s Bluetooth, the angle measurement can be read in the Sparx app, and with the help of the app you also get advice on how to adjust the grinder and how many passes you should make to achieve a precisely centered cup on the rail. The app can also be used to update BEAM software so it always has the latest software version.
