About The Maker Store Actuator Kit The Actuator Kit is available in 3 lengths; 300, 500 and 1000. The following instructions are the same for each length kit. Depending on the version of the kit, the Stepper Motor and mounting hardware may or may not be included. Please note that while we have spent a considerable amount of time and effort putting these instructions together, any errors and omissions excepted (E&OE). If you find an error, please let us know so we can continually improve this resource. Unpack and Check All Components Before starting any build, it is always a great idea to get organised. Start by unpacking your kit and checking it against the BOM (Bill of Materials) in Appendix 1. If you find any parts missing, please contact Maker Store as soon as possible. Tools Required You will also need the following tools: 3mm Allen Key 8mm Spanner 10mm Spanner Screw Drivers M5 Tap Pre-Assembly Notes 1. This build requires some of the V-Slot to be tapped with a M5 tap. In general tap to a depth of 8-10mm and clean away any swarf and burs. 2. When placing any V-Wheels onto the V-Slot, make sure the Eccentric Spacers are adjusted to their furthest point. Do not force the wheels on as this may damage them creating a little burr or bump. 3. The Sketchup model is available for download from the Maker Store website. It is a fantastic resource and can allow you to move through the design, pull things apart, and measure wherever required. We strongly recommend downloading the model and becoming familiar with Sketchup. OX CNC Assembly Instructions 2 v1.0
