This design allows for quieter operation, but also significantly improves stability and rigidity of the y axis. For a double linear rail design, it is important to not over constrain the carriage in order to allow for smooth operation. The design was inspired/remixed from JuanPuchol on Thingiverse and the Rail Holder is a slight modification from Chris Warkocki on GitHub. Be sure to take a look at their respective designs. They work really great as well.
When assembling, please follow these instructions:
- Attach Rails to VSlot Extrusions
- Put Bearings on Rail and Screw in the Spacers with Countersunk screws
- Put on the Y Carriage and Screw in final screws
- Place Extrusions and Y carriage assembly into the frame and align with the aligner.
- I suggest putting on the Rail Holders first and then screwing on the angle corners afterwards
