I think those linear rods and bearing are the weak part of the system. They are too prone to vibrations and whipping around at high speeds. But I’m too lazy to go after more upgrades on my printer at this point.

I do have a standard flow .60mm ObXidian for abrasive filament, but they were a LOT cheaper then. Plus I already have a lot of brass Revo nozzles already. But…I want.
