Belt Installation Y Axis
- Glue the hex nuts into the sockets of the belt clamp (left) to prevent them from falling during installation.
- Attach a screw to the hex nut and push it inside the tensioner (right). Some force might be needed.
- For ease of installation, insert a piece of tape though the carriage hole and attach it to the belt. Make sure that you attach a strip of tape on the underside of the belt as well.
Pull the belt though.
- This is the Belt setup and tightening tool.
- One side helps with pre-tensioning the belt and securing the nuts in place for attaching the top tensioning plate.
- The other side is helps aligning the hex key for tensioning the belt with the bed mounted.
