Testing a mostly-functional espresso machine gui. Somewhat Decent inspired. While I don't have an interface for creating espresso profiles from within the gui, I can write arbitrary espresso profiles/state machines in python which is pretty powerful. Testing with the Puck Simulator.
The profile in the video does the following:
- Cycle water through the tank at 2 mL/s until the water and the group head get up to temperature (I cheated this in the video and turned off heater power)
- Flow water through the group head to the drip tray at 2 mL/s for 2 seconds to purge the air from the group.
- Block off the drip tray, flow to the group at 2 mL/s until the pressure reaches 6 bars.
- Run at a flat 6 bars until the shot weight (estimated from the pump speed/pressure/flow curve since I don't have a built-in scale yet) reaches 32 grams.
- Open the valve between the drip tray and group head to rapidly purge pressure (so it doesn't keep dripping)
- Reset to the beginning and wait for input.
