Dear Artisan user group;
I have received an error I have not seen before using a Mac with the latest solfware : Sierra with a 64 bit system.
We have installed the CP210 driver with our data logger using Omron controls.
Here is a screen shot:
Modbus Error: Read float() hex() argument can't be converted to hex@line 30521
Could it be we have the wrong driver installed?
We use to use the FT232 driver but data driver was upgraded to a new model that has worked with the CP210 driver on most models (this data logger is setup for future use with Bluetooth capabilities)
I'm relatively new to artisan. Been using RoastLogger for years but now that
I have my phidget 1048 I don't need the camera/ocr feature anymore.
I haven't been able to locate the help file or information about the
settings under Config-Device - Phidgets tab. For instance, Async check
boxes, raw data, change etc. I've found everything on the github page, but
maybe I just haven't been successful in pinpointing the proper area to look.
Secondly- I'm roasting on a Diedrich IR-24, which has a thicker J
thermocouple than the one I've hooked up to artisan, which is a K type 1/8in
I purchased here:
The temperatures are around 30 degrees F higher on the thinner K
thermocouple than what the roaster is reporting, even though my
thermocouples in the roaster are mounted next to each other (didn't want to
piggyback on BT of the roaster to phidgets)
Does anyone have any experience in this area? Perhaps the simple fact that
the probe is thinner means the readings will be different, but I do not
know. It would appear that the readings on the roaster are accurate while
the other is much hotter.
Just getting started, and appreciate any guidance.
I try to connect Artisan 1.3.1 to our Giesen W6A (year of manufacture:
2017) with the Siemens S7-Controller.
Unfortnatly the connect does not run with Error-Msg: S7 Communication Error.
The IP-Adress 192.168.2.180 is definitly correct. We use the
Giesen-Coffeeroaster-Software at this time with this IP-Adress.
I have try both settings for Giesen with the same failure:
- Giesen -> WxA
- Giesen -> WxA+
Does anyone have the same configuration which works?
Or another ideas, why that does not work?
Thanks for your helps...
I've been using artisan to control my 2k+ since it was released. I just
can't seem to find smoothing parameters that get me a reasonable ROR curve
once beans are added and the ROR decreases. It looks like the top half of a
sin curve. Marko made a posting recently to Home-Barista that blames that
on the fact that resolution of the 2k+ temperature is integer only with no
fraction of a degree. So when the temperature increases by a degree that
translates into a sudden spike in the ROR which artisan smooths into the sin
curve I see. The lower the ROR gets the more pronounced the sin humps get.
So I'm wondering if it's possible to have artisan control the hottop
temperature and fan speed while at the same time using phidgets to report
the temperature? Or do I have to scrap the whole 2k+ stuff and go with
something like the HTC+TC4C?
Hello Artisan Linux users,
Upgraded Artisan 1.2 to Artisan 1.3 a week ago on an admittedly old
Lenovo T61p running Fedora 28. Since the upgrade starting Artisan takes
more than a minute. Anyone with experiencing similar problems?

Just did my first roast using 1.3.0 and noticed that the Phases LCDs are
working a little differently.
The release notes say that time-to-DRY and time-to-FC were added, and it
looks like these are now the defaults. I have to right-click on the values
to show when DRY and FC are expected to occur. While I do sometimes like to
see the time-to figure, I'm used to watching for when the events will occur
and would prefer not to have to switch to that view each time I roast.
Also, I think the older versions would switch to %DEV immediately upon 1Cs.
Now it seems that a FC time counter is showed instead, and I have to
left-click on the value to see %DEV (I concede that maybe it does change
automatically and there's a delay that I didn't notice before, and it's just
a coincidence that it changes when I left-click on the value.) Again, the
time since 1Cs is useful sometimes, but I would much prefer to see %DEV as
the default when 1C starts, as in previous versions.
I couldn't find any configuration options for the Phases LCDs, other than to
turn them on and off. Are the default behaviors for the Phases LCDs
configurable? If not, I'd appreciate if we could go back to the old
Incidentally, the flyout help on the Phases LCDs says to right-click to
cycle through time, percentage and temp. But the behavior when
right-clicking doesn't correlate with that. It looks like the first box,
DRY% is toggling between % and TEMP and the DRY and FC boxes are toggling
between time-to and when. I think the DRY% box should show a different
header or maybe the % should go away when it shows TEMP, and the flyout help
for the DRY% and DRY/FC boxes should be different. Yet another problem is
that I kept trying to right-click on the headers, which did nothing. Took me
a few tries to realize I had to click on the values. I found the flyouts and
Finally, is this the best place to report issues?
