The Macap MXD utilizes a powerful 340 Watt motor turning at 1600 rpm to drive the large 75 mm burrs. This combination produces quick and consistently ground coffee. The large 75 mm diameter burrs grind the coffee beans quickly (and quietly) which also minimizes the amount of heat the ground coffee is subjected to, which reduces the degradation of flavour. The MXD has an easy to read blue LCD screen to select between dosing sizes (single, double, & manual). Dosing times can be adjusted by a tenth of a second for added precision. To enter programming mode, hold the silver button, located above the LCD screen, for 10 seconds. To navigate through the menu, rotate the silver button.
