LMSC dfk41 Change pre-infusion to 60 second Mate, why does this machine needs 60s PI? Just curious! :-)
CoyoteOldMan dfk41 Don’t know if it’s just me, but your pasted pictures show as boxes. LMSC I think it’s the longest it will accept - it should not be kept as the PI time, but it gives enough time for the pump to get to peak pressure, and thus calibrate the pressure/grind combination
LMSC CoyoteOldMan Ah. I see. If this is the case, why does sage recommends PI of 5 - 15s and PI power of 50-65. I am not sure if these are different.
CoyoteOldMan LMSC Because they are two different things - what dfk41 is suggesting is a way to calibrate the pump power so that it hits 9 bar when it’s extracting (“max pressure”) on a given grind/bean combination. What Sage is recommending are parameters for setting the PI time and pump power (and/or temperature? You mentioned 55-65 °C above as well) for the actual pre-infusion phase.
dfk41 I posted the link to the thread……the bits I extracted are on page 2. I am sure Gary explains what and why but I just remember being blown away by the first shots I had after doing his mod. The link also shows the pictures. It takes seconds to do and is fully reversible.
DavecUK It’s come up as Gary *****, what was the second name, so I can edit the filter. Word filter obviously designed by Barbara Castle.
DavecUK CoyoteOldMan Which explains is, the naughty word filter won’t allow me to use the term old ****, old fart is OK though. It’s a very strange world.
CoyoteOldMan DavecUK I suppose ‘fart’ is more gender neutral, and thus more politically correct in the eyes of the creator of the naughty word list… To think that I used to live in D y k e Road in Brighton. Leading to Devil’s D y k e - meaning ‘ditch’ or ‘trench’.
Pompeyexile Same as I have to say I live near the city famous for Richard Turpin. Blimey! 60s PI? And I’ve just reduced mine from 10s to 5. Oh well, I’ll give it a go. Thanks again
dfk41 Pompeyexile When I did this, I did not understand what on earth was going on, but…….the first espresso had more fruit in it than a can of fruit cocktail! I had been drinking it for ages getting nothing out of it. Let us know matey
