- 1x T-Shape Joining Plate
- 3x 90 Degree Corner
¶ Step 2 - Assemble the frame - Part 1
- 345mm 3060 Extrusion
- 115mm 3060 Extrusion
- 2x Corner Plate
- It is recommended to assemble the frame on a flat surface and to ensure that the extrusions are square to one another.
- Fasten all ten M6x12 screws on the corner plates
¶ Step 3 - Assemble the frame - Part 2
- Assembly from Step 2
- 90 Degree Corner
- Install the 90 degree corner as shown
- Fasten both M6x12 screws on the 90 degree corner
¶ Step 4 - Assemble the frame - Part 3
- Assembly from Step 3
- 270mm 3060 Extrusion
- T-Shape Joining Plate
- Position the 270mm 3060 extrusion as shown. The distances shown should be as follows:
- 100mm
- 140mm
- Install the T-shape joining plate as shown and secure all five M6x12 screws
¶ Step 5 - Assemble the frame - Part 4
- Assembly from Step 4
- 2x 90 Degree Corner
- Install the first 90 degree corner as shown
- Fasten both M6x12 screws on the first 90 degree corner
- Install the second 90 degree corner as shown
- Fasten both M6x12 screws on the second 90 degree corner
- Set the frame assembly aside until Step 8
¶ Step 6 - Prepare the parts for the feet
- side_legs printed part
- 4x Rubber Foot
- 3x M6x12 Cap Head Screw
- 3x 3030 Drop-in T-Nut - M6
- 2x M5x25 Cap Head Screw
- 2x M5x14 Cap Head Screw
- 2x 3030 Drop-in T-Nut - M5
- 2x M5 Nylon Locking Hex Nut
¶ Step 7 - Assemble the rear feet
- side_legs printed part
- 2x M5 Nylon Locking Hex Nut
- 2x Rubber Foot
- Fasten the two M5x25 screws through the rubber foot and into the M5 nylon locking nuts
- Take care not to over tighten the M5x25 screws as you can damage the printed part.
- 3x M6x12 Cap Head Screw
- 3x 3030 Drop-in T-Nut - M6
- Loosely thread the 3030 T-Nuts onto the M6x12 screws. Do not tighten them at this point.
¶ Step 8 - Install the rear feet
- Frame assembly from Step 5
- Rear feet assembly from Step 7
- Install the rear feet assembly onto the frame as shown
- Make sure the printed part is flush with the end of the 3060 extrusion
- Fasten all three M6x12 screws to secure the rear feet assembly to the frame
- Take care not to over tighten the M6x12 screws as you can damage the printed part
¶ Step 9 - Install the front feet
- Assembly from Step 8
- 2x M5x14 Cap Head Screw
- 2x Rubber Foot
- 2x 3030 Drop-in T-Nut - M5
- Insert the M5x14 screws into the rubber feet and loosely thread the 3030 T-Nuts onto them.
- Insert the assembled feet into the ends of the 3060 extrusion as shown. Fasten the M5x14 screws to secure them in place.
- Place the frame assembly on a flat surface and make sure all four feet are level. The frame should sit firmly without any wobble.
¶ Step 10 - Prepare the linear rail parts
- 2x 250mm MGN15 Linear Rail
- 14x M3x12 Cap Head Screw
- 14x 3030 Drop-in T-Nut - M3
- Please refer to the Rat Rig Linear Rail Guide (Steps 1 & 2) for full details on preparing the rails before installation.
- The linear rail carriages are not interchangeable. Do not try to use a carriage on a different linear rail than the one it was supplied with.
¶ Step 11 - Install the Z-axis linear rail - Part 1
- Frame assembly from Step 9
- MGN15 Linear Rail
- Remove the plastic stops installed in the ends of the linear rail
- Do not allow the linear rail carriage to leave the end of the rail.
- Insert an M3x12 screw in each of the holes on the linear rail
- Loosely thread a 3030 T-Nut onto each of the M3x12 screws
¶ Step 12 - Install the Z-axis linear rail - Part 2
- Insert the linear rail into the 3060 extrusion. Position the rail as shown with the following measurements:
- 70.00 mm
- 37.50 mm
- Fasten the M3x12 screws, starting from the top
- Double check the position of the linear rail, using the measurements above
- Fasten the remaining M3x12 screws, starting at the top
¶ Step 13 - Install the Z-axis linear rail - Part 3
- Re-install the plastic stops at the ends of the linear rail
- Check that the carriage runs smoothly along the length of the rail
¶ Step 14 - Install the Y-axis linear rail - Part 1
- MGN15 Linear Rail
- Remove the plastic stops installed in the ends of the linear rail
- Do not allow the linear rail carriage to leave the end of the rail
- Insert an M3x12 screw in each of the holes on the linear rail
- Loosely thread a 3030 T-Nut onto each of the M3x12 screws
¶ Step 15 - Install the Y-axis linear rail - Part 2
- Insert the linear rail into the 3060 extrusion. Position the rail as shown with the following measurements:
- 5.00 mm
- 15.00 mm
- 7.50 mm
- Fasten the M3x12 screws, starting from the left
- Double check the position of the linear rail, using the measurements above
- Fasten the remaining M3x12 screws, starting at the left
¶ Step 16 - Install the Y-axis linear rail - Part 3
- Re-install the plastic stops at the ends of the linear rail
- Check that the carriage runs smoothly along the length of the rail
