PRSalpha to cut complete projects where tool changes are required without additional inputs. The 5HP HSD spindle assembly is fan cooled - in the lower part it has air cooled bearings. The ATC requires 6-7 cfm @ 90 psi of compressed air; PORTABLE AIR COMPRESSORS ARE NOT RECOM- MENDED as they can have trouble keeping this pressure reliably and have a reduced service life.
Page 7: Atc Installation (Mechanical)
ShopBot has been assembled using the instructions provided in the ShopBot assembly manual. This means that the ShopBot is at a point in which it is able to connect and move under the control of a computer. Wire/cable management may be left until the ATC installation has been com- pleted.

Main Air Supply The ShopBot ATC requires 100 psi (7 bar) of air for normal operations. The main air supply should be clean, dry, un-oiled air. It may be necessary to apply inline filters (not supplied) to achieve this require- ment.
Page 14 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Route the other end of the 3/8” tubing through the X-axis E-chain, Y-axis E-chain, and up to the YZ car. Route the 3/8” tubing to the back right side of the spindle (as if facing the spindle). Connect the tubing into the open push-in connection tee.
Page 15 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Connect two pieces of 5/32” tubing to the bottom two push-in connectors on the manifold. Route the other end of the tubing to the front side of the spindle. Trim tubing to length.

There are pre-drilled holes on the top of each end plate for easy attachment. Note: Input #4 will flash red on the computer screen and the ShopBot control software will not allow the ShopBot to move if the emergency stop is not connected.
Page 17 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Wiring the Proximity Switches and Z Zero Plate Run cables from proximity switches and Z zero plate through the Roxtec opening into the control box. Locate the proximity switch on the back side of the Z-axis, located just under the Z-axis motor.
Page 18 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Z Zero Plate Plug in the Z zero plate. The black wire goes in the input #1 terminal and the green (or white) wire goes into the ground terminal (GND) on either the input terminal block or the output block. The red wire goes to +5 (it is only used by the digitizing probe).
Page 19 Connect the yellow, green, white and brown wires to the ATC Interdace Board inside the control box as per the picture below. Connect the yellow wire (cooling air) to the +24V terminal at the front of the ATC Inter- face Board. It will share this terminal with a brown wire from the z-proximity cable. Connect the green wire (ground) to the GND terminal of the Tool Release terminal block.
Page 20 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Connecting Spindle Remove the small socket head screw from the front face of the spindle plug, using a 4mm hex wrench. Plug the cables into the mating plug of the HSD spindle and secure the sock- et head screw to lock the plugs in place.
Page 21 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 The spindle sensor cable is a male Wago connector and will connect into the corresponding female piece on the ATC board. Find the female Wago on the board identified as “spindle sensor cable”.

Page 24 Input 3 – The Y-axis proximity switch is connected to this input. During normal operation, the input “3” light will be off in the ShopBot position screen. If the Y-axis proximity switch passes the proxim- ity targets, the light will turn on. Among other things, this feature will be used for homing the X and Y positions and for limiting the safe table cutting boundaries.
Page 25 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 “5”. Input “5” will appear green until the target is hit then the input goes black.
Page 26 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Touch the grounding clip to the fixed Z zero plate. Input “1” should light up green each time that the grounding clip contacts the fixed Z zero plate. Turn on air supply.

Page 36 Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Snap the collet into the collet nut and thread the assembly onto the tool holder. Ensure the collet is the correct size for the bit needed. Install the bit in the collet and hand tighten the collet nut so that the bit does not slip down into the collet.
Page 37: Zero Tools In Rack (Cn72)
Ensure that there is no tool holder in the spindle. Run the homing routine (C3). A screen will open confirming that tool #0 (empty spindle) is correct. Type “CN72” (custom number 72), to run the ATC zero tools in rack file. Enter the number of the bit to zero and then hit OK.

Page 39: Zero Various Z Heights (C2)
Zero to Various Z Heights (C2) ATC users will only have to zero one bit to their material or bed height each time the Z zero position is changed. The remaining bits in the tool rack will also reference the new position.
Page 40: Regularly Used Atc Files
Calibration for tools in rack Create a Tool Change File The design software must first have the information to enable the ATC to do a tool change. For the software to work correctly, the tooling must be designated to specify particular tool holders.
Page 41: Spindle Warmup Routine (C5)
Automatic Tool Changer (ATC) Installation Manual • December 1, 2016 Within the group, create new tools that will be used with the ATC. The tools created need to have the same tool number in the characteristics of the tool as the location of that tool holder on the ATC. This tool number within the design software is what dictates what tool is selected during the tool changing process.
