Step 9 - Squaring

Squaring the Machine

The final step in assembling your Shapeoko XXL is to ensure the X-Axis and Y-Axis rails are perpendicular (“squared”) to each other and that the Y-Axis Rails are parallel to one another.

Start by loosening the eight (8x) screws securing the Gantry’s X-Axis Rail to the left and right Y-Axis Carriages. Do not remove the screws; a 1/4 turn to loosen them will suffice. The image shows the Y-Right plate, also loosen the Y-Left plate.

Next, loosen the sixteen (16x) screws that hold the left and right Y-Axis Rails to the End Plates. Again just a 1/4 turn is all that’s necessary. Do not remove the screws.

Slide the Gantry all the way to the front of the Shapeoko XXL.

The left and right Y-Axis Carriages should be touching the End Plates as shown in the image below.

Tighten the (8x) screws (four on the left and four on right) that secure the X-Axis rail to the Y-axis plates.

While tightening, pay attention to the Y-axis plates and ensure they continue to touch the end plates as you tighten the screws.

Tighten the front eight (8x) screws (four on the left and four on right) that secure the Y-Axis Rails to the front End Plate.

Slide the Gantry all the way to the back of the Shapeoko XXL so the left and right Y-Axis Carriages are touching the End Plates as shown in Figure X.

Tighten the back eight (8x) screws (four on the left and four on right) that secure the Y-Axis Rails to the rear End Plate.

To complete the assembly, tighten the eighteen (18x) screws holding the baseboard to the baseframe.

Your assembly is now complete.
