Review on π¨οΈ Enhanced Precision: MGN12H Sliding Carriage Printer Machine by Darrin Parasson
Poor quality Extremely rough bottom brackets
Very rough and poor quality bottom brackets. They are actually significantly inferior to the cheap bearings I ordered from China (Banggood). I don't see them usable for 3D printing applications. My current V-Rail configuration is much smoother than this. I only gave BC 2 stars, they were pretty cheap (and I don't usually read BC with 1 star). Update: It seems that extremely poor processing is the cause of the extreme roughness. I've added pictures showing the inner path of the bearing which is misaligned and has a ridge/notch. Looks like the drill bit was misaligned.
