This gets stranger by the minute the boombarista site now links this thread with a sentence that surely doesn't play well with the constructive discussion criteria of this site. Did we offend someone? Why would someone write something like that? Feels uncalled for to me. Frankly the motivation of creating the site in the first place is

That is an amazing job you did to restore that machine! I wasnt planning to touch the exterior much on mine but seeing yours, I need to bust out my BKF....... My E61 rebuild kit is coming in the mail today.... hopefully!

This ^^. And if you can't, you need to adjust the valve stop point. From the "ECM Puristika Review":

People ask mahlkönig that they had more range in espresso so they provided it and while some geek out there might still fancy the old it's probably a minority and in commercial settings it is simply not that important that you loose a bit in cup quality, let's not forget Hemro it's all about profit. I don't understand

When the pump is running and without the portafilter, can you completely shut off the water flow from the group by only using the flow control device?

Thanks. That's quite clear and makes a lot of sense given my experience with my roasts. Happy roasting! Eric

I normally start the timer after I've heard a few cracks, and the pattern can vary a bit between different types of beans. Whichever way you choose to do it, it's best to stick to that method for repeatability

There are typically a few outliers early on, then when you hear 3 or more consecutive pops, that's considered real 1C

Thanks for such compression, I'm sure a lot of people will find it beneficial! After back and forth, my choice was EG-1v3, EK43 (get Titus/SSP burrs + alignment tools), P100 or Titus Nautilus. EG-1 got smaller burrs, and as it seems, great all-arounder. It gives more body to the coffee, but atm I want clarity that EK does

Hi All, When I roast I usually get 1 weak pop, followed by 30 second (plus or minus) until the next pop. Then 1C really gets rolling. Is that first weak pop the start of 1C or do I wait (for timing purposes, etc) until the later more vigorous cracks? Thanks! Eric
