2.1.1 Riser Plate¶
2.1.1.1¶
- Install a riser plate onto the linear carriage blocks as indicated, partially tightening the fasteners.
Assembly Note
The riser plates come as a pair, with a left and right configuration. Refer to the images to ensure the correct one is used.
2.1.1.2¶
- Ensure the riser plate sits flush on the linear bearing block reference edges and fully tighten the fasteners.
2.1.1.3¶
- Partially thread M8 Roll-in T-Nuts onto the fasteners as indicated.
2.1.1.4¶
- Repeat this process to install a riser plate on the other side of the machine.
2.1.2 Riser Extrusion¶
2.1.2.1¶
- Install a gantry interface plate onto a piece of 8080 riser extrusion as indicated.
- Fully tighten the fasteners.
Custom Gantry Height Option
If you purchased a custom gantry height, your 8080 riser extrusion will be a different length than shown above.
2.1.2.2¶
- Slide the extrusion assembly from the previous step onto the riser plate t-nuts.
Assembly Note
Ensure the bottom two t-nuts on the riser plate are facing up, as indicated, and the long side of the gantry interface plate is facing towards the inside of the machine.
2.1.2.3¶
- Bring the gantry interface plate flush with the top of the riser plate as indicated.
2.1.2.4¶
Custom Gantry Height Option
The step is applicable only for those who purchased a custom gantry height.
- Use a piece of dimensional lumber to position the riser extrusion. Determine the length of this spacer by subtracting 200mm (8") from your gantry height (this can be found in the description of your invoice or packing list). For example, the optional 12" gantry risers would need a 100mm (4") spacer.
- After tightening the riser plate fasteners in the next step, remove the spacer.
2.1.2.5¶
- Fully tighten the riser plate fasteners.
2.1.3 Riser Joining Plate¶
2.1.3.1¶
- Partially thread M8 Roll-in T-Nuts onto the fasteners as indicated.
2.1.3.2¶
- Slide the joining plate into the riser extrusion as indicated.
2.1.3.3¶
- Position the top of the joining plate 160mm (6-5/16") above the gantry interface plate as indicated.
- Partially tighten the joining plate fasteners.
Assembly Note
The final positioning of the joining plate will occur while installing the gantry extrusion.
2.1.3.4¶
- Repeat this procedure to assemble the riser on the other side of the machine.
