RB3 (RB1 & RB2) Machined Aluminum Bed Carriage (10 x 10 Bed)
The RB3 Bed carriage is machined from aluminum plate eliminating the bow from stamping and resulting in a very flat mount for the bearings. This helps the bed carriage glide easier and allows the bearings to last longer. The new carriage plate is backwards compatible with the RB1 and RB2 and eliminates the RB2 problem of the bed carriage running into the front of the printer allowing you to use the full 254mm of Y build distance. It will fit the new RB3 frames with the notch facing forward and fits the RB2 with the notch facing to the back.
