Materials and Tools
The vertical boards provide additional structural stability to the frame, ensuring printer geometry does not change with time. For best results, the wooden boards should be sealed so as to minimize shrinking and swelling with changes in humidity.
If your vertical boards have mounting holes pre-drilled:
- The vertical board with a greater number of holes in it should be mounted on the Y vertex, nearest where wires exit from the motor and idler end assemblies. It should be mounted such that the additional holes are near the motor end assembly.
- Skip to Attaching vertical boards
Marking and drilling mount holes in the vertical boards
- Remove the vertical board and drill 3mm holes through it at the indentations formed in the previous step.
- Push M3 x 50mm screws with washers through the holes in the vertical board and then into the idler end.
- Remove the vertical board from the printer and drill 3mm holes at the indentations made in the previous step.
Attaching vertical boards
- Place M3 x 50mm screws with washers in all four holes in the vertical board and then push the screws into the idler and motor end mount points.
- Repeat with remaining vertical boards.
- The vertical board nearest where wires exit the motor and idler assemblies will be home to the controller board and extruder drive. Rotate the printer so that board is facing you.
- Carefully drill 3mm holes through the vertical board at the marks.
- The controller is mounted so that it stands off the vertical board with a series of nuts and washers on M3 x 25mm screws serving as anchors and standoffs. The order of items on the screws, starting from the interior of the printer, is washer-vertical board-washer-nut-nut-washer-controller-washer-nut. When complete, the controller should stand off the vertical board about 1cm and the last nut should be flush with the end of the screw.
- Remove the controller and start nuts on each screw, then washers. Replace the controller board. Put washers and nuts on each screw and tighten them, securing the board to the printer. The exterior face of the last nut should be flush with the end of the screw.
