Setting up the Drum Speed Control measurement
Cropster's Drum speed control allows you to regulate the drum speed directly within RI.
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.
By following the steps below you can set up the Drum Speed Control:
- Open the Roasting Intelligence (RI).
- Navigate to the
Preferences on the bottom left side of the screen. - Select the Machine tab and Configurations.
- Scroll down to the Drum Speed Control measurement and select the option representing your machine.
- 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
The Drum Speed Control bar
The 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.
