Setting up the Gas control measurement
Cropster's Gas Control allows you to regulate the gas directly within RI.
If the Gas control measurement is not shown in the Preferences in RI, it must be added before it can be set up.
The following information is relevant only if your roaster has been successfully connected to the computer you have configured.
If you encounter issues, please refer to your machine's setup manual available on our Helpdesk.
By following the steps below you can set up Gas control:
- Log in to Roasting Intelligence (RI).
- Navigate to the
Preferences on the bottom left side of the screen. - Select the Machine > Configurations tab.
- To choose the Roast machine, click on the dropdown menu in the Machine section.
📚 To view your roast machine in the list, make sure to add it via the online platform C-sar beforehand. -
By clicking on the + Add connector option, you can choose your connector from the available options in the drop-down list. You need to select the relevant connector from the dropdown.
- Click Select to add the connector.
-
Navigate to the Machine > Controls tab. To activate the Slider controls, simply click the green toggle button.
- Scroll down to the Gas control measurement and select the connector option representing your machine.
- Click Save to finalize the changes.
Once you have set up a profile using Gas control, the Profile can also be replayed.
This means Cropster automatically reproduces the Gas settings applied during the creation of the Profile based on Bean temperature.
The Gas control slider
The Gas control slider is in the bottom-right corner next to the machine's measurements:
Roasting with Gas control
Start your roast as you usually would in the RI.
Rather than making manual adjustments to Gas on the roast machine's control board, you can conveniently utilize the Control slider located on the right-hand side of the Roasting Intelligence (RI).
- For small gas adjustments, use the - and + buttons.
- For big adjustments, use the Control bar by dragging and dropping the slider.
- For instant adjustments, click the percentage values shown on the Gas control bar to instantly adjust the gas value accordingly.
- Input values directly and receive immediate feedback as you adjust the Control sliders
- Detach the control slider by clicking on the
Detach sidebar button. 
Replaying a roast
As soon as you have recorded one roast with the Gas control bar, set this roast as the reference to enable Replay Assist.

Never leave the roast machine unattended while replaying a roast. Cropster replays the roast and captures the details, but you are always responsible for monitoring the roast machine to ensure it is operating safely.
It is recommended not to enable auto-start during replay and to closely monitor any early gas adjustments. This approach allows for immediate intervention in case any unexpected issues arise during the roasting process.
