Cannot control Falcon 500 motors using Phoenix X Tuner

Technical Programming

Hi,

We have been trying to test our motors using Falcon X Tuner, but the motors don’t respond. We have been able to set CAN IDs and update all of the firmware to non-pro v5, and have tried enabling the robot in FRC driver station. Nothing has worked.

Has anyone else encountered this problem?

Thanks for your help.

Hi!

Typically, not being able to control motors in Tuner is the result of one the following.

  1. Driver Station is not enabled.
    • Driver Station AND the enable button in Tuner must be enabled
  2. The control request you are using requires gains. If any of the requests you are attempting are closed-loop control, you must have gains in Slot 0 or configure Accel if MotionMagic.
  3. Old diagnostic version for your firmware version. Ensure your diagnostic server is up-to-date

Can you share a screenshot of your Tuner while trying to control a device AND your driver station?

I see you mentioned the diagnostic server. I wasn’t able to figure out how to update it to the newest version.

Take a look at Running the Diagnostic Server (ctr-electronics.com)

I managed to get the Diagnostic Server installed by flashing a new Os version to the roborio. Installing the new version of the roborio OS allowed us to use newer phoenix tuner features. In order to install the diagnostic server, we had to upload code to the robot that had any CTRE objects and that installed the diagnostic server. We can now control the robot.
