Dosing by burr rotations also takes ramp up/ramp down out of the equation. I can't see how time-based would be better than burr rotations, since burr movement is directionally proportional to output. Time has inherent non-linearity built in, which is fine once you've set a dose, but if the start/stop ramp is inconsistent, you'll get inconsistent output, even

Although I use a Decent tamper for my daily driver, I occasionally use a couple of beautiful regular tampers (with a tighter fit) that are more satisfying. I use my fingers and thumb to start the tamp evenly by feeling the edge of the basket. I have no plans to ditch these "conventional" tampers

I would assume that id has 2 reasons for stopping, the required torque drops to zero for a long time or the required torque stays at zero for a long time. I would guess if you feed slowly and evenly enough you hit the second trigger as feeding slowly enough might not trigger the torque has passed X and now

IMHO there's no need to spend speedster and strata type of money to get what u want. I have a Nurri L type SA spring Lever machine that has a 3 channel PID that is able to set and regulate the temperature of the grouphead vs the brew boiler vs the steam boiler (its a. Double boiler) independently. It heats

Another update from DHL - apparently there is not a sufficiently good record of the name and address of the manufacturer, and this is being requested from the Italian end. Hopefully when this is completed, the shipment will be released. So near and yet so far!

Dosing adjustability of the outer burr is in steps of 0.1 revolutions, so the weight equivalent least count in dosing is 0.123 gms (20 gms / 16.25 rotations) and positional accuracy of the burr at that value depends on the resolution of the encoder. If the encoder is only 100 steps per revolution, than the positional accuracy of

Thank you. I feel better!

I am trying third wave water for the first time. Can I save any excess water from my kettle or should I discard it?

Looks really good, love the coffee bar layout...so neat as well

Ramp/soak PID controllers are fairly inexpensive now, and using them on inlet temperature is a lot more robust in control terms than on bean (outlet) temperature, due to the faster feedback. The ramp/soak allows you to program separate ramp up and straight line times. You can also use several segments of faster, then slower ramp up rates, if you want;
