Bear MGN12 Y axis

thingiverse

Beta version of my Y Axis MGN 12 Railed X axis for the bear. Note: I was a cheapskate when I started this project and went with 2020 for the ends, which has paid off since I don't lose any Z height with this design. I'm simply using cheap rails (350mm length - without support). They take the load of the bed just fine (and have less flex than standard 8mm round rods) so I think they will be okay. I'm using a cheap Y Carriage that's only 3mm thick (https://www.aliexpress.com/item/32970453139.html...). So if anything, that's the weakest link in my setup. I believe the rails will be fine. An extra bearing block (2 on each side) might be a nice luxury, but it's not required. The bearing blocks I'm using are designed specifically for this carriage. I'm also using old-fashioned end-stops, so one of my MGN mounts has a recess to accommodate this.
