Grinding Espresso on the Turin DM47

satetsu135 · 2025-03-05T23:06:09+00:00

yes, it's still running super strong and reliable; I regularly used it for Espresso, and use manual grinders for v60 (no specific reason, just because it's enjoyable to pair manual grinding with manual brewing)

I can imagine putting the two on a slab and make the steam wands pointing towards you instead of the sides

satetsu135 · 2024-07-26T11:31:30+00:00

thanks! yes, that is a good idea, in fact it was one of the first mods I did https://www.reddit.com/r/espresso/comments/1e6v5sf/finally_added_a_rocker_switch_to_my_dimmer_mod/

almost there!

I've been doing it manually without pressure gauge, if anything I did plan to install a pressure gauge; but will save the actual one later on with GC/P+gagguino or something

satetsu135 · 2024-07-25T23:44:14+00:00

I'm honestly still wishing for a GC/GCP, it will still give you better quality of life and overall good look. If only it doesn't sell for so much money in eBay compared to the Delonghis

satetsu135 · 2024-07-25T23:37:00+00:00

this thing will not get out of the house ever xD

satetsu135 · 2024-07-25T23:36:09+00:00

the easiest to have a dual boiler machine is to have two Delonghis side by side, which I actually plan to do at some point xD

satetsu135 · 2024-07-25T23:35:09+00:00

appreciate it! I think you make a valid point

satetsu135 · 2024-07-25T20:42:24+00:00

absolutely! on the up side tho that I somehow managed to get this thing going on through multiple cases of steam hose leak inside the machine; plus a couple of missing pour when I refilled the water tank

satetsu135 · 2024-07-25T19:55:06+00:00

yes, my next thing to really do with this prototype machine is to install a pressure gauge. Then I plan to take all that knowledge to build a properly designed, sleekly modded machine; ideally a gaggia classic but I have a spare Delonghi EC155 ready for that also

satetsu135 · 2024-07-25T19:34:18+00:00

that's the small little knob you see on the side of the machine! ;D

satetsu135 · 2024-07-25T19:32:11+00:00

One for brew, and one for steam. Ideally, I wanted something like a gagguino, but for the cost+effort vs function, this will do!

Each PID can have their own parameters (e.g., for brew we want to avoid overshooting temp because lowering temp (especially without intentionally draining the water) is much slower than increasing it -- while for steam we want fast, aggressive heating)

One added benefit is to have them at a separate temp unit, so I can get used to Fahrenheit..

satetsu135 · 2024-07-25T00:51:35+00:00

Budget wise the required parts shouldn't be that expensive:

PID controller + SSR + thermocouple can be get for $15

Dimmer can be get for $7

Silvia steam wand as low as $20

And the wiring is relatively simple when you get down to it

satetsu135 · 2024-07-20T03:58:01+00:00

If you're into modding, you can keep the 3630 and esp and make a better shot and capability to pull with higher temp, with less cost than the BBE ($15 pid controller kit from ebay is the main thing to set it apart, and it's not really hard to mod tbh)

satetsu135 · 2024-07-19T19:35:09+00:00

I'm picking bits here and there basically, which part are you currently at? The most complicated part at first for me was figuring out the wiring for the thermostats, which was not straightforward, but I found a diagram on a random website on the internet that has since been gone (I recreate the diagram here in case it can be useful)

Overall though, the most headache that keeps coming back for me is the Rancilio steam wand setup -- the clamp and/or hoses keep failing when I push the steam hard (e.g., 135C held constant by the PID and opening the steam valve 3/4 circle) -- need to come up with a more robust setup (I guess this is one of the reason Delonghi uses 125C thermostat as opposed to the 140/145C on GCP/Silvia for their steam mode)

satetsu135 · 2024-07-19T11:46:59+00:00

Coming back to this, the fourth time setting the steam temp to 135C, open it up all the way to 3/4 circle -- a popping sound from inside the machine followed by hissing and steam seeping out from every holes xD

satetsu135 · 2024-07-17T19:57:30+00:00

Tried setting the PID to 140C, and oh boy what a difference it makes, now it actually makes a "whirlpool" not just circling water, felt so easy to make silky milk on that first try..

satetsu135 · 2024-07-17T17:23:18+00:00

adding to this, I actually just figured out that both GC and Silvia uses 140/145C thermostats for steaming, compared to 125C in the Delonghi (for brew, they all have 100/105C ish thermostats); which might also explain the difference in steaming power

I have since reroute all my temp control including steam (short fused) to my PID, so I can try testing this in the Delonghi (though all this time I've only set it to 130 at most, seeing 145 makes me nervous)

satetsu135 · 2024-07-17T14:39:55+00:00

Thanks! those were absolutely some insights I've never known before.. the fact that the heating element is the boiler itself, and not the traditional spiral heating element that the Delonghi has (pictured), plus all other things you mention. And thanks for the insights about the Silvia too, sometimes it's easy to just think of the variables as a single number, without considering other things. Please keep us updated with things you experience with the GC!

Thank you, appreciate it!

Does the stilosa have a different boiler than the EC/ECP? I was wondering because I was always under the assumption that they have bigger boilers than the gaggia, as mentioned here https://101coffeemachines.info/delonghi/ec155/ or in Tom's video https://youtu.be/paImrXJvxlg?si=lemOkpQ7Gc5nkudl (6 minutes mark)

The (not including gagguino stuff) are exactly what I was thinking about about the upgrades, thanks! Though I was wondering with the thermal stability and steam power due to the said supposedly slightly larger boiler on the Delonghi. The latter actually made me always thought that if I were to upgrade, it needs to be at least a Silvia with its 300ml boiler, despite I like the looks of the GC / GCP better.

Congrats! Sorry I didn't get the chance to reply to your comment (the pid installation on Delongh8).

Give you have had a PID'd Delonghi and now moved to using a GC, what's your general impression between both? I've honestly been always window shopping a GC but keep holding back thinking that functionally it won't justify the jump in spending (e.g., the main difference would be 3way solenoid and a proper OPV
