I just made my GF a decaf cappuccino. At 1/4 turn it's not allowing any flow. Right before 1/2 turn a trickle begins to flow from the shower screen.

She's not a coffee fan, but liked it.

Thank you! I'm unfortunately not seeing your review on the Chris Coffee website just yet. This might be a stupid question, but what do you turn measurements signify (e.g., 1/4 and 1/2 turn)?

Seems much better than what previous posters have experienced, which is exciting.

Do a search once you get to the Chris' Coffee website for "Flow Control " for the review. It possibly is still not posted pending approval. Let me know if you can see it.

The Flow Control adjustment lever turns in a 360 degree circle. 1/2 turn is 180 degrees, a full turn or 1 is 360 degrees, 1 1/2 is one full turn of 360 degrees plus another half turn of 180 degrees, for a total of 540 degrees. Hopefully, this makes sense.

Yes, that makes total sense. I wasn't aware that you could turn it more than one full revolution. Thanks for sharing!

This is the latest. Installed by Chris Coffee on a new Quick Mill Alexia.
Somewhere between 1/4 and 1/2 turn it starts to activate slightly. I have only had it 2 days. Seems right to me.
YMMV
I just got my QM Alexia with QM flow control, also installed by Chris'. My results are very similar. 1/4 turn actually gives me zero flow though.
1/2 gives ~1.5ml/s
3/4 = ~4.2ml/s
1 = ~ 5ml/s
1 3/4 = ~7.5ml/s

Thanks for posting. Congratulations on the new machine!

That is pretty close to what the flow profile is on mine. At 1/4 I get no flow. Flow starts right before 1/2 turn.

Thanks! I'm really enjoying it. The ease of use and the quality of the shot are both night and day from my previous setup. The flow control is a bit hard to manage, I find, but I'm sure I'll get better at it. I need to reposition my knob so that the area between 1/2 and 3/4 turn is in a better spot. Controlling it requires a little more delicacy than I would like, but that seems to always be the case with espresso. I also wish the knob was shaped differently, perhaps more of paddle shape, so that I didn't sometimes accidentally touch the very hot grouphead directly underneath and to its sides.

A paddle shape makes sense, but it has to be small enough to fit the space.

I totally agree on the Alexia!
