# Risers

In this step we will install the risers that create a rigid connection between the Y-Axis rails and the machine base.

Insert 2x M5 pre-assembly t-slot nuts into the top slot of each Y axis makerslide rail.   These will be used to hold the belts in a later step.

Begin by placing 2 M5x10mm socket head screws through the bottom holes on the riser plate and loosely thread an M5 Tee Nut onto each.&#x20;

Place the riser against the corresponding Y axis and then thread 2 M5x14mm socket head screws through the second and third holes from the top per the image below.&#x20;

Using a 4mm hex key, tighten all 4 screws on each riser. Repeat this process for the remaining 3 risers and ensure that the orientation of the riser plate aligns with the edge of the stiffeners.

You can use this point to check that your Y-Axes are square and level using the [Calibration and Maintenance guide](/x-carve-assembly/calibration-and-maintenance.md#squaring-the-y-axis-rails). You will need to loosen the stiffener panels to avoid damaging them when shifting the rails.&#x20;
