Step 2 - Base Frame Assembly


The base frame is the main sub-structure of the machine. Supporting the rail and the gantry system, it is important that you follow each step in this section to ensure your machine base is stable and secure.

Item Description Quantity
1 Front and Rear End Plate 2
2 Cross Strap 3
3 MDF Wasteboard Half 2
4 Adjustable Leveling Feet 4
5 M5 x 25mm BHCS 18

Leveling Feet

Carefully screw in the four leveling feet, two per End Plate. The feet will only fit in the outermost nuts on the bottom of the End Plates. Turn the Leveling Feet knobs clockwise until the top of the threads is flush with the backside of the nut.

MDF Baseplates

Lay out the three Cross Straps (parallel to each other and with 12” of space between them) as shown in the image below.

The Cross Straps will be placed so the flanged edges are facing down. Note that there are two threaded holes in the center of each Cross Strap.


Rear Baseplate

Place one MDF Baseplate across the back half of the Cross Straps as shown in the figure below. Place the MDF Baseplate so that the six countersunk holes on the long side are farthest away from the centers of the Cross Straps and the MDF Baseplate is flush with the edges of the Cross Straps. (This should reveal three holes running across the middles of the Cross Straps that will be used for the second MDF Baseplate.)

Insert 3x M5x25mm screws into the three countersunk holes as shown in the figure below. Turn the screws until they stop but do not tighten.


Front Baseplate

Place the second MDF Baseplate across the front half of the Cross Straps as shown in the image below. Place the MDF Baseplate so that the six countersunk holes on the long side are farthest away from the centers of the Cross Straps and the MDF Baseplate is flush with the edges of the Cross Straps. (This should cover the remaining three holes running across the middles of the Cross Straps.)

Insert 3x M5x25mm screws into the three countersunk holes as shown in the image above. Turn the screws until they stop but do not tighten.


Rear End Plate

Carefully lift the rear edge of the Cross Straps/MDF Baseplate assembly and insert a single End Plate as shown in Figure X. Note that the flange on the End Plate will go beneath the Cross Straps and the six holes drilled into the End Plate will match up to the six countersunk holes running along the rear edge of the two MDF Baseplates.

Insert 6x M5x25mm screws into the countersunk holes of the MDF Baseplates and screw them in through the Cross Straps and the End Plates. Turn the screws until they stop but do tighten.

Front End Plate

Carefully lift the front edge of the Cross Straps/MDF Baseplate assembly and insert the remaining End Plate as shown in the image below. Once again, the flange on the End Plate will go beneath the Cross Straps and the six holes drilled into the End Plate will match up to the six countersunk holes running along the front edge of the two MDF Baseplates.

Insert 6x M5x25mm screws into the countersunk holes of the MDF Baseplates and screw them in through the Cross Straps and the End Plates. Turn the screws until they stop but do not tighten.
