Motor controller flickering

[Wildcats1378]

Hello everyone,

We've been having a mostly minor issue with one of our robot functions. Our shooter is a catapult, but instead of having it always tensioned, we tightena loosen the tension via a window motor.

Our problem is that sometimes, when pulling the tension back, or motor will flicker, or skip. I thought it could be a mechanical problem with or mechanism not being perfectly square, but when I traced it back to the motor controller, it appeared the light was flickering between yellow and green very fast.

We changed the battery, thinking it was a voltage problem, but it was still intermittently there. We thought it could be a coding problem, but releasing the tension back works fine, and it sometimes pulls the tension fine too. I'm basically all out of ideas.

Any advice is greatly appreciated!
