I can’t seem to get rid of unpleasant harshness and dryness
Yeah , it was for the most part.
Then I’ve been doing some more testing, I’ve been setting machine to 90,91 degrees as stated above the problem is no longer there around these temperatures. Then I set temp to 97 to see if even less water and more steam will be coming out, I just uploaded one random video to show the issue, temperature is set to 94 degrees with +2 off set for most of the time.
And another update, just had my machine on for over hour but set off set to -4 with 94 and the issue is not here anymore.
What is the manufacturers suggested offset for that machine.
They’ve usually calculated what is required for proper operation at the group .
Also, What do you mean by offset is +2 “for most of the time”

Cuprajake sorry I owe you apologies then, I through all comments again and I honestly missed your link you posted, in avalanche of comments it happened.
Well I have two questions then, my machine allows only to be set to 99 not 100 degrees , is that ok for this calibration?
I assume that off set setting in that case should be set to zero?
I meant that temperature is set to 94 for most of the time.
Off set is by default to +2 .
Yeah, .
For me temp or more temp stability is key,
Unless you have a scace device you will never know for certain what the temp is
But like grind size as long as you can assign a number to that setting, and it’s repeatable, it’s just a number.
Once you sort your temp it could be something a simple as that, while I still think it’s the beans
Go back to basics, get temp sorted use the stock basket, it will allow a coarser grind, put the vst in the drawer for a while. Get a repeatably prep system and go from there, even if it means buying 2kg of the same bean to get used to what your changes do.
I’ve never been a massive fan of square mile.

The only info i have without a Google is for the synchronika . Do you have the similar info for your machine?
So for the synchronika the offset is set at 15 degrees C by ECM. I once did a video showing how good the syncka was but cant find it now . I never had reason to change the manufacturers settings .
What was yours originally set at.
I will say again for clarity the below is for synchronika

I mean such device with wires is not that expensive , 20-30£ unless it’s not accurate in that price range. I can also always borrow one from my workplace we use them .
If that is correct then my off set is meant to be -6 at -5 it already starts flash boiling and you can hear paper tearing/steam sound.

Adrianmsmith - you’ve missed a few posts :) - most likely in the other thread.
Essentially… ECM/Profitec in their infinite wisdom have decided to pre-code an offset in the machine. What’s wrong with zero? But no… let’s just think of a value and add there… 42 anyone? In Fahrenheit maybe? 🫠The user can now add or subtract 10 from whatever their preset offset is. And yep… your guess is as good as mine on what this pre-coded offset is…

Read on… 🥳
Adrianmsmith no I haven’t found such info in manual , just this . It says the default value is 0 but mine came with +2
MuddyOne I mean such device with wires is not that expensive
As Jake said, you’ll have an idea… but it will be by no means accurate. Just google Scace-II device.
And as Jake said, it’s just a number. It matters not. But your machine should not be overheating after being idle for 1 hour. It’s not an HX machine. You might reduce the temp, but it might mean your water is now too cold at the start (I.e: sour coffee).
Your retailer should test your machine with a scace device and go from there.
MediumRoastSteam I did the off set calibration posted by Jake . I’m of course still waiting for retailer to come back but I can try to see where this calibration takes me, if it’s true and correct then my off set is meant to be at around -6 if it was at + 2 then no wonder I’ve been getting constantly bitter espresso.
MuddyOne I did the off set calibration posted by Jake
Not sure what that is. What I am saying is… you machine seems to be overheating after being idling. Change the offset, do what you want… but if the trend is the same (temperature increases when idling) then you got to ask yourself what’s the temperature after 35 minutes from cold?
This is not normal for a dual boiler machine of this class.
Anyway, good luck sorting things out. There are a few issues going on. Overheating is only one of them.
Didnt realise there were 2 threads. i give up!!
The offset is to take account of the system as a whole, and the fact that the measuring point is not in the correct position as designed.
It shouldn’t need correcting in normal circumstances.
And adjusting it whan theres a fault isnt the way to go, repairing it is .
Without some numbers to go on now this is all a waste of time

MediumRoastSteam There are 3 distinctive issues here:
- your machine is overheating (but you can just quick flush until this gets sorted). You need to contact the retailer for that, something we can’t help you with. I am unsure how you’ll measure the temperature of the coffee with a thermocouple and no other equipment meaningfully, but I’m sure @Adrianmsmith will help you here (I’m curious to know that one);
- your puck is deteriorating halfway through, as per your video. I think your coffee is stale.there’s only one way to find out, already discussed.
- you may not like the coffee from SquareMile, specially red brick. Personally, in my view, that is a great crowd pleaser. But taste is taste. And this is totally unrelated to the issues 1 and 2.
I know you posted about this before, is there other issue you noticed ?
- Edited
MuddyOne - nope. Where did you buy your machine from if you don’t mind me asking? And where are you based in the UK?
MediumRoastSteam can recommend vacuum bags ? Also you reuse or wash them?
I can definitely now smell lack of aroma from the 1kg bag, I think that reopening that large bag for a month is too much . I could still smell nice aroma week ago but today morning is definitely gone, I will start freezing my beans.
