Not sure yet, but I think it helped a little. I was having severe squeaking on z-hops, and that seems to be a bit better.Did it help? im going to try this too but i only have half the amount of smoothing rods though..
I installed my dual gear feeder yesterday. I had to increase my esteps almost a third to extrude properly. Im guessing the smaller diameter of the grip wheels were to blame..
Works well but its more noisy on retraction. The spring is much higher quality and the tension is adjustable, what luxury!
EDIT: I lied, it's still squeaking, LOL! Just took longer to get there, since I'm 13 hours into a 28 hour print of various parts.
