Using Drum Speed Control & Replay Assist

This article introduces the setup for Cropster's Drum Speed Control/Replay Assist feature.


The following article and its screenshots refer to Roasting Intelligence (RI5). 

In case you previously used Roasting Intelligence (RI4) we kindly invite you to check the newly improved features of RI5. 

To upgrade to RI5, please download the Roasting Intelligence (RI5).

If Drum Speed Control is currently in beta for your specific roast machine, and you haven't been invited to participate in the beta program for this integration, but you are interested in participating and testing the feature, please sign up here.

Beta-testing means that the features are being tested with a selected group of users to help us identify minor flaws under everyday conditions that we cannot reproduce internally. If you want to participate and test the feature, please sign up via the link above.


Setting up the Drum Speed Control measurement

If the Drum Speed Control measurement is not shown from the RI's Machine preferences, the control measurement must be added before it can be set up.

The following applies, if the roaster has already been successfully connected to the computer you have set up. If not, find more information about your machine's respective setup manual from our Connect Your Roast Machine page, or our Helpdesk.

    Cropster's Drum speed control allows you to regulate the drum speed directly within the RI. To learn more about how to set up Drum Speed Control for your roast machine, please see below:

    1. Open the Roasting Intelligence (RI).
    2. Navigate to the gear-png-2 Preferences on the bottom left side of the screen. 
    3. Select the Machine tab and Configurations

    4. Scroll down to the Drum Speed Control measurement and select the option representing your machine.
    5. Save your changes.

    Once you have set up a profile with a reference using Drum Speed Control, the Profile can also be replayed. This means Cropster automatically reproduces the drum speed settings applied during the creation of the profile based on bean temperature. 

    The Drum Speed Control bar

    Drum Speed Control bar is in the bottom-right corner next to the machine's measurements, and can be hidden by clicking the Hide button.

    If you previously used RI4 you might have already noticed the change regarding the +/- signs of the Gas Control bar which we would also like to draw attention to: 

    In RI5 the -/+ buttons have a reversed position. The - is on the top left and the + is on the top right side of the Gas Control bar. 

    Roasting with Drum Speed Control

    Start your roast as you usually would in the RI. Now, instead of manually adjusting the drum speed at the roast machine's control board, use the Drum Speed Control bar at the right-hand side of the RI.

    • For small drum speed adjustments, use the - and + button.
    • For big adjustments, use the Control bar by dragging and dropping the slider.
    • For instant adjustments, click the percentage values shown on the Drum Speed Control bar to instantly adjust the drum speed value accordingly.

    Replaying a roast 

    As soon as you have recorded one roast with the Drum speed 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.
