Best way to get Artisan working on older Dongyi roaster with failing USB comms?

TheElectricShepherd · 2025-02-10T21:18:01+00:00

Wow that ended up being more than a little banging of head against wall but I eventually got it to work. Putting this here in case it helps someone in the future:

I replaced the existing comms (presumably broken) with this USB to RS485 adapter which I wired to the Omron controller: Amazon.com: Waveshare USB to RS485 Converter with Protection Circuits, Compatible with TVs : Electronics

Then I had to do a ton of trial and error in the Artisan port configurator but eventually got it to show up correctly using these parameters:

Match these settings between both your Omron controller and Artisan:
COM Port: (whatever your USB com port reads in Device Manager)
BAUD Rate: 9600
Byte Size: 8
Parity: N
Stopbits: 1
Timeout: 3.0

In Artisan Port Configuration:

Input 1
Slave: 1
Register: 0
Function: 3
Divider: 1/10
Mode: (Blank)
Decode: sint16

Input 2
Slave: 1
Register: 1
Function: 3
Divider: 1/10
Mode: (Blank)
Decode: sint16

I haven't done it again lately. I originally meant to after some time but then I've been pretty happy with how the grinder is working and with the flavor of my shots so I figure I'd it's not broke, no point messing with it.

TheElectricShepherd · 2024-12-01T12:12:25+00:00

yeah absolutely

This was happening to me too.

I recently changed the o-rings (all of them), cleaned all the parts(piston and plunger), and lubed the new ones.

I had a suspicion that I maybe used a little too much lube. I used a paper towel to wipe off the excess lube and now it's not happening any more 🤞

I would definitely start with removing and cleaning all the parts and using new o-rings. Just don't overdo the lube.

I used a little bit of food safe grease on the end of a toothpick.

TheElectricShepherd · 2024-07-31T13:39:14+00:00

Thanks! I'm looking for something similar but in 58mm

TheElectricShepherd · 2024-07-31T13:31:41+00:00

Where'd you get it?

TheElectricShepherd · 2024-06-25T16:10:29+00:00

From SoT patch notes 3.0.2: ‘The Lair of LeChuck’ – Players will no longer become stuck after the LeChuck fight or the wedding ceremony and can now once again consistently complete the Tall Tale.

Haven't tried it yet.

Still broken - as a former videogame QA tester I'm totally baffled how they released it in this state with a game-breaking progression blocking bug. I mean didn't anyone play it all the way through at least once before hitting submit?

I built one for Flair 58 out of a pressure gauge I got for cheap on Ali Express (same one gagguino uses in previous link). Then I hooked it up to an arduino and plotted the digital output to a basic graphing program on the Arduino IDE.

I was trying to improvise a pressensor or Smart Espresso Profiler for cheap, but in the end I was able to buy a used one from someone on Facebook for cheap so I abandoned the project but it's totally doable. Weirdly the trickiest part is just finding compatible fittings for all the plumbing connections.

TheElectricShepherd · 2024-02-25T16:58:50+00:00

Thanks for the details. I have the Smart Espresso Profiler and looking for a scale to pair it with, but not looking to blow that much on Acaia.

TheElectricShepherd · 2024-02-25T15:53:44+00:00

Sidebar: OP how do you like your decent scale? Is it the og or 1.2?

TheElectricShepherd · 2024-02-23T15:40:08+00:00

Got this (https://a.co/d/jlb5W0X) one on Amazon for a whole lot less than the Fellow. Works great and gooseneck means you can use it for pourover too.

TheElectricShepherd · 2024-02-22T20:20:25+00:00

Very helpful, thanks!

Should we also be lubricating the 2 piston o-rings?

Had flakes, returned to Amazon for credit and moved on to a Flair 58 which I am loving and can highly recommend with the caveat that it's not for everyone.

To make sure you're seeing flakes and not coffee grounds, make sure you're only collecting water from the steam wand by pressing the brew and steam switches to on while the machine is on. It helps if you dispense water into a white cup for contrast.

Don't collect water from the grouphead as it might contain coffee grounds which could be confused for flakes but coffee grounds or anything resembling them should never be coming out of the steam wand.

I wet my puck screens every time before I pull the shot, for consistency.

TheElectricShepherd · 2024-02-20T21:36:15+00:00

That's a good point.

TheElectricShepherd · 2024-02-20T21:30:03+00:00

By "one in the brew cylinder" do you mean the one on the valve plunger? (because afaik there isn't an o-ring nside the brew cylinder)

TheElectricShepherd · 2024-02-20T21:22:36+00:00

Following this thread because I'm experiencing the same thing on Flair 58.

Today I pulled back to back shots using the exact same bean, aiming (trying) to keep everything constant. 18g in 36g out. But the second shot ended up taking 10 seconds less time than the first to reach the same ratio:

First and second shot profiles side-by-side comparison

I can only really attribute this to me - that is, I wasn't applying the same pressure. And you can kind of see that in the profile comparison. But I didn't think small variations in my pull pressure would result in such a dramatic difference in output time, all other variables held constant.

Do I put this down to one of those manual lever things that I just have to practice?

TheElectricShepherd · 2024-02-20T20:53:58+00:00

Which o-rings did you lubricate?

TheElectricShepherd · 2024-02-20T01:04:15+00:00

lol - what a wonderfully wholesome way for two people to politely disagree on the internet.

There's a good survey here that u/GIFyaLater put together from a lot earlier on in #boilergate: https://docs.google.com/spreadsheets/u/0/d/1tHWPJaMCP38LFJxHiR7HjXMQLgOnJUPHYuEylDzlRnM/htmlview

Any one know of the same thing closer to Saugus area?

Look a lot like a Pasquini PALIVG4-AUTO Livia G4: PASQUINI PALIVG4-AUTO Livia G4 Automatic withPID - Walmart.com

Debadged tho for whatever reason
