Etzinger etzMAX LM – espresso grinder with integrated scale
One press of the red START button, the grounds fall loose and fluffy into the portafilter, and the weight is already on the display – the etzMAX LM combines precise grinding with weighing in a single device.
The etzMAX LM combines features of the etzMAX LightW and the etzMAX M. It grinds directly into the portafilter if you wish, weighs as it goes and is designed for a clean, even shot.
Grinding mechanism, scale and adjustment
The RRB mechanism with a rotating grinding ring and anti-static jig ensures even, fluffy grounds and dissipates static charge. The built-in ACAIA scale works to an accuracy of about ± 0.1–0.2 g and can be run in timer or weighing mode. Adjustment is simple: stepped macro in 0.1 mm increments and stepless micro in 0.01 mm increments. Retention is under 1 g, so hardly any coffee stays behind in the grinder – ideal for single dosing.
Construction and upgrades
The housing of the grinding mechanism is die-cast zinc (good heat dissipation), the grinder body is aluminium, with a solid front plate and red START button in front. The modular construction makes swapping components and cleaning easy. The grinder can be converted to a filter version (Filter Kit) and upgraded to the PLUS version with forced-air cooling. Since 2022 it has run a new DC motor.
