Also, a light scuff with ~200 grit sandpaper before gluing helps adhesion between the layers without affecting finish. Be sure to remove the protective masking tape from the acrylic before gluing. Superglue works well to attach the two sheets. You can either source 11 mm thick acrylic, or you can glue two of the 5.5 mm sheets together. These are thicker to meet the required tolerances for the related axes. This sheet contains the Z-axis trigger block and the Y-axis switch holders. 2.4 mm end mill for pocketing holes for M3 nuts.3.175 flat spiral end mill for cutting out each part with tabs.3 mm drill bit for drilling the various M3 sized holes.

3 mm flat end mill for facing off the individual pieces (facing exposes the 2020 extrusion alignment rail).There are also tool changes required between some of the operations, so it is recommended you run each operation separately to make sure you do not have issues. Alternatively, you can use the reference pin method. You can fashion a makeshift machinist square by gluing two small pieces of wood together to form a 90° angle. Remember the double sided operation requires precise work holding for WCS. This milling operation is two-sided so special attention must be paid to work holding and consistency between setups. It also contains a spacer for the right-side X-axis limit switch. This sheet contains the X-axis and Z-axis holders.

2 x Snap Action Limit Switches (V-15-1C25) (can be made by removing the actuator of either of the two above or purchased at Amazon).2 x Long Actuator Limit Switches (V-153-1C25) ( Amazon).2 x Roller Limit Switches (V-156-1C25) ( Amazon).1 sheet of 12 mm (11 mm) cast acrylic which is at least 90 x 70 mm ( SainSmart).1 sheet of 6 mm (5.5 mm) cast acrylic which is at least 90 x 110 mm ( SainSmart).It also allows you to “home” the machine so you can get repeatable and consistent machine coordinates. This allows you to protect your machine from violent crashes, damage, and other unfortunate incidents. This tutorial guides you through the process of adding X, Y, and Z-axis end stops/limit switches. This project file and tutorial are designed for the SainSmart 3018 Pro.
