Overview of Your ShopBot PRS CNC Tool
Note that the diagrams in this manual depict a generic ShopBot. Depending on the size and
shape of your tool, the table layout may look a little different (fewer or more legs, different
shape, etc.).
Before you unpack and start to assemble your ShopBot PRS tool, let's go over the some of
the major components and get familiar with the terminology and directions we'll be using:
THE TABLE To get us located, refer to the orientation diagram above and imagine looking
at the tool from the position of the little man in the drawing. From this position, we'll call
the lower left hand corner of the work area the tool's 0,0 (or home) location. The X-axis is
the long length of the table and values increase going to the right from where you are
standing. The Y-axis is the narrow width of the table (or front to back from your position on
the long side) and values increase as you move away towards the back. The Z-axis is the
vertical movement or the plunging and withdrawal movement of your tool. Decreases in Z
values are plunges down by your cutting tool. Increases are movements of the cutting tool
up.
Still looking from the position of the little man, consider the furthest away X-axis track that
the bearings ride on to be at the back of the tool, the track nearest the little man to be at
the front, the left side the left, and so on. As you're positioning your tool in your shop, keep
in mind that you will typically be loading sheet material from the left or right side so you
should be sure to leave yourself some room to move around at one or both ends of the tool.
We'll use the words or 'car' to refer to the entire moving unit of a particular axis. The big
gantry is thus the X Car, and the one that rides on it, the YZ Car.
