Review on 🖨️ MGN12H Carriage Printer Machine: Revolutionizing Linear Printing Technology by David Sanchez

The quality of the 400mm MGN12 rail I received was mediocre at best. They were cheap (and discounted) so I feel like I hardly got what I paid for. The initial power had some significant *knocks* as the bottom bracket slipped. After disassembling the bottom bracket, I found that there were more gaps in the ball races than I was used to seeing. Maybe a few extra balls were needed? I couldn't fully degrease, but I added some EP2 grease and manually pushed the bearings over the ring to spread them out. Reinstalling the sled left rails good enough for my Raven's X-gantry. I'll probably look elsewhere and spend a little more next time I need the rails, but they work well enough once cleaned.
