The info you provide is very terse.
“SF6” is probably http://www.sanfranroaster.com/sf-6lb <http://www.sanfranroaster.com/sf-6lb>
And “Watlow" I assume to mean http://www.watlow.com/products/controllers/temperature.cfm <http://www.watlow.com/products/controllers/temperature.cfm>
My hunch is you maybe just connected the cables without making sure that variables like baud speed, even/uneven, parity, stopbits are all set exactly the same on both ends.
SF should be providing that info / assistance in their manuals / service desk.

I've been using the Artisan program for some time now on an Ambex ym2 with
an Omega data logger and a 2 ghz dual core laptop. I just loaded 0.8 and
I'm hoping that I might get smoother ROR values with this version as I see
that is one of the improvements. Maybe the issue is the fast response of my
probes? Is there a way to compensate for this in Artisan? Can you make
some recommendations as to the EXTRA settings for the newer version and
maybe something up to date about the effects of using values too large or
too small? My ROR just jumps around too much and by the time it's
dropping/rising too rapidly it's almost too late for me to do anything about
it. Could I benefit (or not and why) from using over sampling or a higher
or lower sample rate? I'm at 4.0 now. Which curve smoothing values affect
real time displays and which don't? I've been reading Scott Rao's new book
and find myself evaluating my roasts and looking carefully at ROR and 1st to
drop percentages so Artisan is so useful. Thanks so much to all that have
contributed to this great program.

Hi I would like to post the following question to the forum please
I have an FZ-94 roaster and I'm having difficulties getting Artisan set up correctly and reading the temperatures.
The model I have is equipped with an RS-485 - USB converter model UT-885 and I have configured the Artisan software according to the instructions in the link below:
http://artisan-roasterscope.blogspot.de/2015/01/connecting-artisan-to-coffe…
I believe I have done everything correctly up to this point, however the software still comes up with the following error message:
Modbus Error : readSingleRegister () Modbus Error : [Connection] Failed to connect[rtu baud [9600]] @line 25150
Can anyone help me solve this issue and get the software to work correctly please?
Thanks,
Reece
Flint,
I just downloaded the build from the GoogleDrive (Ubuntu 32bit) and it says 0.9.8 (7), so build 7 (file data: 11.11.2015). Humor font did work. So which build did you install and where did you get it from? I also quickly downloaded the corresponding binary from GitHub and it seems to be the same (did not try to install that one).

Question for users of LInux (ubuntu specifcally) artisan.
Does the humour font function on your artisan 0.9.8 (4)?
I think Marko reported that he fixed the bug that disables it, but I
re-installed from latest version and for me it still doesn't work.
Thanks!

I made another clip, this time in split screen mode, demonstrating the way I use Artisan to execute a pre-planned roast profile:
http://kostverlorenvaart.blogspot.nl/2015/12/split-screen-roasting.html
If more users shared such videos, also with a walk through of all settings for specific roaster / controller setups, that could help new users enter into the hobby or even profession.
Hi Sam,
this works nicely in Artisan and I am using it all the time, to see whether my heater is close to ceiling. The red curve shows heater power in %, the blue curve is fan power in %. The green curve is the preset roast profile and brown is the actual bean temperature closely following the profile.
I am using a PIDed popcorn roaster with a PWMed fan, so I can change fan speed and heater independently. I am roasting almost all batches using the ramp and soak feature. I also log the fan speed from my popper, so I can compare things later. However, fan speed is semi-automatic (I define temperature events to reduce the fan to 90% at 160C and 80% at 200C).
How to do it: I am using my own code on an Arduino (not a proper TC4), but using the Artisan TC4 settings. Here are the Artisan settings:
And extra devices
You have to send the following over the serial port:
AT, ET, BT, HeaterPower, FanPower,SetValue,Nothing, eg.
“0,0,205,90,95,206,0” indicates 205C BT, Heater Power 90%, FanPower 95%, set Value 206C
To do this here is the code snippet that is executed whenever Artisan sends “READ;”
The variable input has the temperature, Output has heater power, and so on.
Hope that helps,
Christian

Betreff: [Artisan-user] Including TC4 heater PWM on plot?
I've seen a couple of people on here plotting their heater duty cycles in artisan and I'm wondering how to make it work with the TC4+arduino.
I have a homemade setup using a manual speed controlled shop-vac and artisan controlling the heater. The fan can easily overpower the heater if I'm not careful and it would be helpful to monitor when the heater is nearing 100% duty cycle so I can turn down the fan to help get more heat into the beans.
One day I'll automate this once I figure out how to detect good fluid bed circulation but for now it's easier to have a knob and adjust airflow by eye.
Has anyone had any luck plotting and displaying the TC4 heater duty cycle in real-time?
Thanks,
Sam

Hi Folks,
I am attempting to convert my old National Instruments profiler for my
Ambex Y2M.
Got ET and BT working through 1046 Phidget.
I am hoping I can use the gas valve and signal conditioner listed below,
to have control of the burner out put through artisan.
Can anyone suggest a compatible device?
Hope that makes sense, this is kinda a foreign language to me.
Thanks
Dan

Not sure what you mean by “Pidgets screen”. The Pidgets I know don’t have a screen. Anyhow, in case you have the Pidgets control panel open to se the readings, close this. The Pidgets stack supports only one client. As long as the control panel (client 1) is connected, Artisan (client 2) cannot receive values.
Hope this helps,
Marko
