My team recently added a second flywheel to our two-falcon shooter. This flywheel is identical to another five pound, steel flywheel on the shooter. To be perfectly clear, we now have two flywheels on our shooter.
However, when I set the velocity of these Falcons to say 4000 rpm (the gearing is 2:3, falcons to shooter wheels) , the motors spin up to between 2000-2500 rpm, and sits there for about 2 or 3 seconds before proceeding to the desired speed.
It did not do this before, which makes me wonder if this second load is too much. I have tried tuning the PIDs of the falcons, greatly increasing the P to try to get it to oscillate. Unfortunately, I got to a value of 5 or so and saw no significant acceleration changes past that.
Any ideas why the motors could be idling like this? Anyone else encounter this issue?
