I have wondered for some time about the Matrix shower screens. The stack creates 1.5 bar of back pressure, which will hold the water back for longer during fill. However, they likely also impede max flow. Still, would be fun to play around with one and to find out how it affects the shot.
That kind of approach is mainly suitable for med-dark roasts, though.
Be aware, I modified my blind sleeve.
No longer a “standard safety system” although it retains a lot of damping compared to the standard open sleeve.
Mine has 4 × 1mm holes and to me it works fantastic now.
You could not do the 30 second test with 1 × 1mm hole as back pressure would trip the pump as it hit set point for “ pre infusion ”
You also dont get the same full flow shower as on video above.
My current set up is great for me and allows 19.5g with the acs puck screen in the acs 32 basket.
54.4 tamper
Noone that matters will agree but it’s an improvement for how i want to work with it .
And if the impossible did happen, i.e i knocked the portafilter off id rather be hit by the lever then, than with an open cylinder 😎
Has anyone actually ever done that?

Yes, I’ve seen the holes you drilled. I had ACS measure the fill rate, and was told it’s 22.5ml/s if the pump is set for 6-bar. I’m sure I’ll have to experiment with it for a while to work things out for certain shot styles.
I’m just counting down the weeks, but the wait is actually useful; the adjacent room is being renovated, after which the room for my office can be painted, and I’ve just found a carpenter to make the coffee bar that I need for the machine. Lots going on over Xmas.
Is that with the blind / safety sleeve or the standard open sleeve fitted.

They didn’t specify.
I suspect it might be with the safety sleeve, I would expect without the safety sleeve the flow/fill rate would be even faster, the pump has a good capacity.
I asked on the discord app the de1 can hit 12mls

Cuprajake Whoever said that is quoting the number it can/could be set to, rather than the actual output it can achieve. In reality, most machines top out at 8ml/s and a few go a little over (depending on AC mains voltage), but nothing known out there hits 12. Decent were recently considering lowering the max value that can be set, because it is misleading.
A recent post from Colin (works for Decent Support) confirms this:
I also went and read the Discord - here is the last reply to you from Rohan:
when i ran tests myself on a fast profile i think mine topped out at 7mls

Yeah 7 to 8 is the normal range. There are a few guys in Asia that can only get 6, due to the mains voltage there.

Adrianmsmith lol. On that subject, I’m at 280 microns of burr gap (80mm lab sweet clones in Fm grinder) for a mere 12.7g dose that gets hit with a declining 9 bar profile. Small group diameter and quick compression really helps, but don’t tell the fb crew that!
back up for sale?
@Raja123 they cock or just trotting?

No payment (some reserve just to show good faith), so I cancelled and relisted.

What does that mean 🤔

if someone commits to buy, but can’t give a date on when they’ll pick it up, I think it’s fair for me to ask for a hold payment. If no answer, I relist.
Ah, i see, yes.

Absolutely!
Well, it sold for 2250, sans the exotic baskets, which I will now sell separately. Hoping the person that purchased the DE1 does follow up, heh. More so because ACS just emailed me to let me know the Vostok is being picked up by DHL and will be delivered over the Xmas break.
hope the buyer read the listing properly or they are guna be pissed for £100 lol
