Using modulox systems for shooter, but CIM motors not moving fast enough to shoot ball.
So start playing around with compression of the balls and other motors.
Compression on the ball can be a big factor but so can your gearing choice with the Modulox. We can probably help you with your selection but would it be possible to share some pictures or maybe a cad of your set up? You can post here or email me directly at firstname.lastname@example.org and we should be able to help you.
