I have a Monoprice Maker Select Plus, where I'm doing the Gulf Coast Robotics carriage plate upgrade. I was watching through an installation video just to find any "gotchas" I might want to watch for, and the guy in video recommends removing one of the carriage bearings, going from 4 to 3. The idea is to get quieter, smoother travels, with less weight on the belt.
Has anyone else here done this for this model printer? Or for the very-similar Maker Select v2/2.1? Are there any downsides I should watch for? Everything I know seems to indicate 3 bearings are just better (the whole "3 points define a plane" thing), but if it's that simple, why go to the cost of shipping with 4?
I did end up making the switch, and it has worked well. One thing I've noticed is markedly increased ringing/ghosting. However, it should also be noted I switched to a stronger (heavier) build plate at the same time, and that likely is also contributing.
