Increasing the Heat


Up to Artisan v0.9.7 custom event buttons could only set absolute event values. The version 0.9.8 adds the possibility to define buttons that increase or decrease an event value relative to the last one registered.


To define such a "relative" event button, set its type to one of the available types from the popup prefixed by +/- and put the intended offset as value (e.g. -5). You can also set an event action if needed and put potentially a command to be send (e.g. for the case of MODBUS or Serial actions) in the description field. Any placeholder of the form {} in that description will be replaced by the new event value (and not by the offset value specified).




For example, instead of the extra event buttons to set the heater and fan of a Hottop KN-8828B-2k+ to absolute values, one could use two buttons to increase and decrease the heater as well as two buttons to increase and decrease the fan by 10%.

  1. I like the addition of the % control value for buttons. I've already implemented the feature and it will help me follow the natural log curve. You're rockin' bro!!!

  2. Hi Marko,

    Has anyone else reported the BT and ET being flipped when using a Hottop with Windows? I'm questioning whether it is a Microsoft USB driver. 9.8 RC worked fine then I put in the 9.8 release but hadn't roasted until today. I'm using Windows 7 Pro 64 bit and the OS did several patches since the last Artisan install. I unloaded 9.8 and loaded 9.5 up through 9.8 again. All of them are now switched. ET in Artisan is BT on the Hottop. I had to change all of my Alarms to track ET which screws up the TP, ROR and temperature readouts on the graphics. I changed out the Hottop control panel (I have a backup), moved the USB wire to a different port, changed the USB wire, shutdown the computer completely and restarted . . . nada. I was still able to roast but this is too bad. I'm positive 9.8RC 2 worked fine until the most recent patches from Microsoft.

    If this is the first report then it is unique to my setup. Worst case I'll just go back to manual through the software and dump the alarms. Hopefully that will get the graphics back to tracking and noting BT for TP and temperature ID on the graphics.

    1. Hi gjkenney, this doesn't fit well here. You may consider signing up the Artisan mailing list to get fast response on such specific questions from the community.

      Under menu Extras >> Tools, tab HUD, there is a flag named "ET <-> BT" that allows to switch the ET/BT signals.

    2. I'll do that and thanks Marko.

  3. Hello!
    I'm interested in manually plotting changes in both airflow and gas input mid-roast, as I manually and/change these roast factors.

    Until I can upgrade from my current 2-probe (ET/BT) datalogger, I'm stuck with finding a way to manually input these other data.

    Can I create buttons (or is there another method?) for inputting these changes on the chart mid-roast, along side the automatic data logging, for future visual reference?

    Thank you. As i'm learning this software, i'm finding it invaluable.

    (Not sure is this upgrade applies--i'm still new to the software. Feel free to direct me to a more appropriate place for my question.)

    1. The burner settings are recorded here directly via a network connection between Artisan and the roasting machine. That works only on some setups using a corresponding setup, like those Probatones. It might be possible to place a thermocouple at the place the hot air enters the drum (if you are talking about a drum roaster) to record a value that should correlate somewhat to that of the actual burner level. You have to make sure that this thermocouple is certified for those temperatures especially if you move it quite close to the flame.

  7. I'm running version 0.9.8(1) but don't have the button types that are prefixed with +/-. Do I need to enable them somewhere?

    Thanks in advance...

    1. Yes, you need to define them your self as custom buttons (menu Config >> Events, tab Buttons). You can use the picture of this post as a guide. Once defined, you can make those buttons visible by showing the custom buttons bar (menu Config >> Buttons or just press key b).

    2. What I was trying to say was I don't have the button types for "±Heater" or "±Fan" as in your picture.

      I'm using the HTRI board installed in a HotTop 8828B.

      Here is a screenshot of the button types available to me right now:

    3. Strange. Could you re-download and re-install Artisan v0.9.8, check again and report?

    4. Downloading and reinstalling seems to have fixed it. Thanks!

  8. I have implemented these but the results aren't as expected.

    I have a button configured for "Fan -50" Starting with the fan at 90%, if I hit the "-50%" button, the fan slider reflects the fan at "40%" instead of 45. From 100%, it does indeed go to 50%. From 75%, it goes to 25%.

    It looks like it isn't a relative percentage. Instead it's a straight modification based not on percentage nor on the previous value, but rather a simple numerical subtraction of the absolute number (100).

    I've verified this on both 0.9.8 and 0.9.9.

    Here is a screenshot showing my button configs:

    1. This is the intended behavior. The specified values is just taken as an offset to the previous value not a relative percentage.

  9. Ah, okay. Well a relative percentage would be useful! Something to think about when you're adding new features. =)

    It would be especially useful for alerts...

    Thanks again for the quick reply.

  10. Hello guys I am very new in artisan, do you have or know a link to any video showing how to follow my previous profile. Before artisan I used to follow my previous curve profile on my excel, I can' t figure out how to follow a profile using the software.
    Thank you very much
