Are you curious about how much adjustment is needed to setup your Macap grinder, or how to program it? Well we made a video to help with that!
The burrs will break in and become more consistent over the first few pounds of coffee, but you do not need to worry about pre-seasoning them before use.
The video shows our recommendation of setting the grind time first and then adjusting the grind coarser or finer to get the correct volume of coffee for your portafilter and basket (16-18 grams for most spouted portafilters, 20 grams for most bottomless portafilters). Once you have the right volume of coffee set, start pulling shots. If 1.5oz of espresso is dispensed faster than 25-30 seconds, adjust your grind finer. If your 1.5oz espresso takes longer than 30 seconds, adjust your grind coarser. Also keep in mind that because there is a small amount of coffee inside the grinder, adjustments won't be instantaneous (so be careful not to overcompensate based on the results of your first test after an adjustment).
