As co-owner of Baratza and the creator of the Sette (with lots of help!) I wanted to weigh in on some of the comments and speculation around the Etzmax grinder in hopes of setting the record straight. Baratza and Etzinger have been working together very closely for almost 8 years to bring to market the Sette (for Baratza) and the Etzmax (for Etzinger). Christian Etzinger has been working on the "Hotmill" grinding technology for over 10 years! While the grinding technique and process in the Sette and Etzmax are the same, the mechanism is totally different. (Sette is a horizontal motor & pinion/crown gear drive, and the Etzmax is a vertical motor and belt drive in a totally unique mechanical housing) We use different DC motors as well. The burrs are the same size, but the tooth geometry is quite different between the two grinders resulting in different grind performance. The Etzmax uses the Sette front display, but the main power board is unique to each model. Our weight based models both share the same acaia weighing technology, though the Etzmax has totally different porta-filter support. Wherever useful we share parts to maximize use of tooling investments (I.e the hopper-stopper handle, display panel, grind adjust collar). We have a close and very cooperative relationship between our two companies. The Etzmax is targeted to be a "professional" grinder. It is all metal construction, much bigger and heavier (about 3X) than the Sette. Christian is a brilliant engineer and we are lucky to benefit from his genius. We wish him well as he embarks on his new journey with a complete professional coffee grinder (vs. burrs only).
I hope this answers some of the questions and speculation that has been floating around.
