Introduction

This manual begins where the assembly guide ended. It is assumed that the machine is fully assembled and

connected to power.

For sections concerning software, this manual assumes that you have a basic familiarity with the CAD/CAM

software.

Section 1: Safety

Basic Safety Rules:

Learn and understand safe use of the machine. Do not allow untrained individuals to operate the machine

without supervision. Ensure everyone who operates or works near the machine knows the location of the

emergency stop switches at all times.

Eye and ear protection MUST be worn by the machine operator as well as any bystanders or observers. Flying

sawdust, material chips, and other debris can cause serious eye injury.

Wear closed-toe shoes at all times.

Make sure that material is properly secured before cutting, and be aware of any small parts that may come loose

after being cut out. If a small part catches the edge of a spinning bit, it can be thrown forcefully in any direction,

causing injury or damage.

Never place hands on the rails of the ShopBot. Be aware that the machine may move unexpectedly in any

direction, which can cause serious injury if hands are in the path of movement.

Never wear gloves while operating the machine. As with any power tool, a glove can get caught in moving or

spinning parts and pull hand into the machinery.

Never leave a machine running and unattended. Understand that a spinning tool generates friction and heat,

creating a risk of fire. This risk is minimized by using correct chip load (read more about this in section 2), using

sharp bits, and by always double-checking files before cutting. Be prepared to pause or stop the cut if something

seems incorrect or unsafe.

Keep a working fire extinguisher within reach of the machine, for the reasons listed above.

or equipment damage.

WARNING: FLYING DEBRIS AND LOUD NOISE.

Wear eye and ear protection. Ignoring

instructions can result in serious injury or

equipment damage.

SAFETY INSTRUCTIONS

- Keep shields in place and wear eye protection

- Do NOT locate metal fasteners near or in the cutting area

- Verify clearance of tool path before cutting

- Use bits that are clean, sharp and in good condition.

- Use bit manufacturer’s recommendation for speed and depth of cut.

- Insure that collet is in good condition and that bit is fully inserted.

- Machine must be supervised while in operation.

- Read user’s guide for more information about proper work piece mounting and use of router

bits.

Section 2: Software Setup and Orientation

For software installation, refer to “Uninstall/Reinstall ShopBot and VCarve Software” document located under

“Software” on ShopBot website (www.shopbottools.com/ShopBotDocs/software).

Loading Software and Drivers

Do not connect the Shopbot to computer before installing the software and drivers!

Special note for schools and large companies: This software runs best with full administrative permissions

enabled. We strongly advise against setting up separate admin and user accounts on the control computer.

For international customers: The computer used to run the machine MUST have the language set to United

States English in order for the software to run correctly.

Connect Shopbot to Computer

After loading software, locate the USB 2.0 hub included with machine. Connect this to computer, and connect

main USB cable from control box to hub. ONLY this cable should go into the hub. Do not connect the RPM

controller cable (if applicable), flash drives, etc. Power on the machine, and double-click the Shopbot 3 icon to run

the control software.

If an error message is received regarding the connection, try some of the troubleshooting steps at

http://www.shopbottools.com/ShopBotDocs/maintenance.htm. Call or email Shopbot tech support if needed.

Loading the correct settings file

All ShopBot machines are controlled by the same software, so it's important to let the program know what kind of

machine is being used. All settings can be set at once by loading a default settings file.

A prompt will occur to allow a default settings file to load for the machine the first time the program is opened.

The following screen should appear:

Page 9

For machines built after 2007, double-click on PRS Shopbots. If loading a Desktop Tool, choose the file named

ShopBot_PRSDesktop2418.sbd. If loading an Alpha Tool, open the PRS Alpha folder and then choose the correct

table size of the machine. This will go back onto the main screen.

Understanding the Shopbot control software

The screen is divided into two main sections:

The console window (left) allows adjusting settings, loading part files, and entering commands. The position

window (right) is how the machine provides “feedback” in terms of its coordinates, switch positions, and alarms.

The Basic ShopBot Command Principle

Whether issuing instructions to the ShopBot from the Control Console or from a Part File, there is a standard Com-

mand Language for controlling the tool. Each ShopBot Command starts with two letters. For example, a [Z3] com-

mand stands for Zero the location of 3axes (X, Y, and Z). It is helpful to understand that all commands are located

within the drop-down menus in the console window. The first letter of each command corresponds to the menu

that it’s in. To load a part file, click on File > Part File Load, or enter an [FP] command.

Entering Values (Parameters)

In some cases, the command must be followed by parameters that fully define the move or action. For example:

An [M2] command (Move 2axes) will normally be followed by two parameters: an X coordinate and Y coordinate.

So [M2] 3,2 will move the machine to the (3,2) location on the table. However, this command can be used to

move only one axis by omitting one of the parameters. [M2] 3 will move only the X axis, and [M2] ,2 will move

only the Y axis. Notice the use of the comma as a placeholder for the X parameter.

Page 10

What's in a Part File

The list of instructions is provided through Part Files that are written or generated in other software and brought

into ShopBot. The list of instructions looks just like the list of Commands you would enter from the keyboard. On

each line of the list, there is a two-letter Command followed in most cases by parameters. A Part File can be a

short and simple list that looks like the following:

JZ, .5

J2, 10, 10

MZ, -.25

M2, 20, 10

M2, 20, 5

M2, 10, 5

M2, 10, 10

JZ, .5

This example instructs the tool to cut a rectangle. First (JZ, .5), jogs (moves at rapid speed) the bit up to make sure

it is above in the material when moving to the starting point. Next, the tool will jog to the XY location (10,10). This

is the starting point. Then the bit is moved down to -.25 (MZ, -.25) at Move speed now because it is cutting into

material. The next four commands move the bit to each corner of the rectangle. Once the part is cut, (JZ, .5) jogs

the bit up out of the material. This is a simple example, but should help explain how a part file works.

Switching from English to Metric units:

To work in metric units, click on Values on the

top menu bar, then choose Display Values. Or,

type a [VD] command to access this window.

Change the first field from inches to

millimeters. Click OK at the bottom right

corner of the window, which will save changes.
