I changed my code some: Specifically my drivetrain speed. I changed it from 70% to 10% for tests, and it successfully downloaded, but when it finished downloading and had all normal indicators of doing so, it never actually changed speed, at all.
We tested several different wires for this.
What may be causing this, and how can it be fixed?
We’re going to need some more information.
I’ve given you all I have. What more do you want?
The code?
It does this with all programs i’ve made. Blocks, text, brand new codes, codes that have successfully updated previously, etc.
And…can we see a program?

This is the main code partThis code doesn’t move the robot.
It doesn’t have to. This code lets the robot drive and work mechanisms in driver control, but when I change anything about it (notably velocities) it changes nothing about the drive or mechanisms. For example, the drive is moving at 50% speed and has no change at all when it is redownloaded to 1%, 10%, 100%, and other speeds. The same applies to our intake, catapult, etc.
You should share the code that does this.
What @2775Josh is saying is that this code does not move the robot at all. We need to see the code where you actually tell the motors to move. The code that you currently has only sets the speed of the motors but doesn’t tell the motors to start moving. If your robot is moving then it is not running the code above. Is it possible that you are running the clawbot code that is on the controller when you just click drive?
An easy way to check that your program is running is to see if all the things you are printing on the brain are actually showing up on the brain.
I had a similar issue I recommend getting a new downloading cord and if that doesn’t work fully restart your computer.
If you have just assigned the drivetrain to a controller joystick in graphical setup, then this has no effect.
The code that’s auto generated by the graphical setup will simply send controller joystick values directly to motors (using setVelocity followed by spin).
Move away from graphical setup and write the control code directly.
How do you do this? (chars)
I have code to make the robot move in the side panel
I’m using C++. (chars)
I’m sure you can find the same page for C++ with a google search.
I created a basic drivetrain that has a velocity switch so that every time you hit the up button it increases the velocity by 10% and every time you hit the down button the velocity goes down by 10%.
