Introduction

The ShopBot Automatic Tool Changer (ATC) automates the bit changing process during projects that require

multiple tool changes. The ATC reduces the time a project must remain on the machine by automatically

changing bits between cuts, thus eliminating the need to change and calibrate tools by hand.

The ATC system includes:

A 1HP Teknomotor spindle

Filter/regulator with low pressure switch

Six-position tool bar

Magnetically removable dust skirt

ATC interface board

The 1HP Teknomotor spindle assembly is fan-cooled. The ATC requires 4 scfm at 90 psi of clean, dry, un-

oiled compressed air. PORTABLE AIR COMPRESSORS ARE NOT RECOMMENDED, as they can have

trouble maintaining this pressure reliably and have a reduced service life.

It is not recommended to leave a tool holder in the ATC spindle when not using the machine. When you are

done using the machine all tool holders should be removed and stored in the tool rack at the rear of the tool.

Using the software to change to tool #0 (explained on page 17) will accomplish this.

Connecting the Pneumatics

Locate the filter/regulator included with your tool. Inside the bag will be a mounting bracket and two

M5x12mm Button Head Screws. First, attach the mounting bracket to the rear of the tool on the corner

opposite the red power switch. Remove the plastic nut from the regulator and drop the regulator into the

bracket and thread the nut onto the regulator to lock it in place. Pull the blue main pneumatics hose from

under the tool and insert it into the orange quick-connect fitting. Plug your shop’s air-line into the fitting on the

left side of the filter.

ATC Software Setup and Tool Calibration

This portion of the installation covers the software setup and tool calibration.

Install the ATC Software

Download the latest ShopBot control software from the ShopBot website:

http://www.shopbottools.com/mSupport/controlsoftware.htm

If an earlier version of the ShopBot control software is present, uninstall the software and install the most

recent version. Refer to “Uninstall/Reinstall ShopBot and VCarve Software”

at http://www.shopbottools.com/ShopBotDocs/software.htm

Note: If there are personal files within the “SbParts” folder, be sure to rename or move this folder so the files

are not lost.

ShopBot Setup (TS)

Type in “UR” or go to “Utilities” pull-down menu and select “Reset default Settings”. Select the file name that

correctly describes the machine (under the “PRS ShopBots” folder, then

ShopBot_PRSDesktopMAX3624.sbd)

Move the cutter to the location that is to be “0, 0” (the reference point for programming) on the

table. Open the ShopBot control software and open the “ShopBot Setup” file in the “Tools” drop-

down (TS). Read through the window and click “Next”. The second window is the “Tool Settings”.

(0,0)

Go step-by-step through this window while verifying

information about the machine. Make sure that the check

boxes for the Z zero plate and proximity switches are checked at

the bottom of the window. Select the radio button marked

“MAX ATC”. Click “Next”.

In the “ShopBot Setup (Z Zero Plate)” screen, measure the

thickness of the plate and enter that value. Make sure the input

switch is set to “1”. DO NOT check the “Yes, I want to always zero

my Z axis at the same place on my table”. Click “Next”

At the “ShopBot Setup (Prox Switches)” screen, select

“Make it easy on me…” and click the “Click Here To Make It

Easy On Me” button to start the zeroing routine.

The next screen is “X and Y axis zeroing setup”. Read this screen and click

“Run the prox switch setup routine”.

Follow the prompts from the pop-up screens. Select “Yes” to

open the keypad for any adjustment to the “0, 0” home

position, then click “OK”. The default home position is the

corner of the spoilboard near the machine’s natural “0,0”, but

you can set it wherever you want if you are using a specific

jig or fixture.

Move the machine to the zero point, and hit “ESC” to exit the keypad

mode.

Click “Yes” to zero out the X and Y axes and click “OK”.

done.”

Software Inputs and Outputs Check

Ensure that all of the inputs and outputs are being recognized by the automatic tool changer (ATC) by

checking for each of the cases outlined in this section.

Inputs

Inputs are signals that the software receives from devices that cause the tool to have a specific reaction.

Input 1 –The Z zero plate and the fixed Z zero are connected to this input. When either of these

plates are connected to a ground, the circuit is closed and input “1” on the ShopBot position screen

lights up. The tool’s fixed z-zero plate does not require a grounding clip, however use of the

standard z-zero plate does.

Input 2 –NA

Input 3 –The X, Y, and Z-axis proximity switches are connected to this input. During normal

operation, the input “3” light will be off in the ShopBot position screen. If one of the proximity

switches passes the proximity targets, the light will turn on. Among other things, this feature will be

used for homing the X, Y, and Z positions and for limiting the safe table cutting boundaries.

Input 4 –This input is connected to the stop switch. When inactive, the switch allows for use of the

tool and when active, the connection is severed and the tool comes to a stop.

Input 5 –NA

Input 6 –Tool bar in extended position, ready to make tool change. Lights when tool bar is fully

extended.

Input 7 –Tool in spindle. Lights when tool holder is properly inserted into spindle and clamped.

Input 8 –Drawbar open. Lights during tool change when draw bar is open and tool holder can be

inserted or removed.

Outputs

Outputs are signals that ShopBot software is sending to cause a desired action. Unused outputs can be

programed to activate other peripherals using an optional relay board.

Output 1 –Runs the spindle.

Output 2 –NA

Output 3 –NA

Output 4 –Turns on during machine operation (safety flashing screen). Required for spindle “on” signal.

Output 5 –NA

Output 6 - NA

Output 7 –Toggles the toolbar forward and backward. When output 7 is triggered, the toolbar should be

extended and ready for a tool change.

Output 8 - Toggles the spindle drawbar open /close (releases tool holders from spindle).

Caution: When the spindle is not spinning it is possible to drop the tools from the spindle if Output 8

is activated.

Basic Function Check

Check that all systems involved are working properly, starting with the proximity switches.

In keypad mode (K) move the X-axis into the proximity target

using the left arrow on the keypad. The proximity switch will

have a red LED lit until it comes across the proximity target,

when it will turn off. Moving off the top of the target should cause

the LED to come back on. This should also be evident in the

ShopBot position screen when looking at input “2”, the light will

turn from black (normally closed) to green (open).

In keypad mode (K), move the Y-axis into the proximity target

using the down arrow on the keypad. The proximity switch will

have a red LED lit until it comes across the proximity target,

when it will turn off. Moving off of the target should cause the

LED to come back on. This should also be evident in the

ShopBot position screen when looking at input “3”.

In keypad mode (K), move the Z-axis into the proximity target using “Page Up” on the keypad. The proximity

switch will have a red LED lit until it comes across the proximity target, when it will turn off. Moving off the top

of the target should cause the LED to come back on. This should also be evident in the ShopBot position

screen when looking at input “3”.
