I have the same filament printing in my machine right now (but mine is white).
To adjust the driver, I like this video: https://youtu.be/89BHS9hfSUk
But the limits she chooses are nuts. If it’s a drv8825, I set mine to 0.5V, and yes, you adjust can adjust it while it’s in the ramps board, but but but! It is very sensitive, and if it gets too high, it could damage the motor. I disable the stepper motors first (you can move the motors by hand when they are disabled). Don’t disconnect or reconnect steppers with the ramps board powered.
