...
Mounting Bracket If you don’t have an (optional) Automatic Tool Changer (ATC), you must use an additional mounting bracket to install the SmartCool:
PathPilot v1.9.7 or Later Required PathPilot v1.9.7 or later is required to use these instructions. If you haven’t yet done so, download and install the latest version of PathPilot from tormach.com/pp-updates.
...
Complete the following steps in the order listed:
Install the Head Unit
Identify the two pre-existing mounting holes behind the spindle on the head casting.
...
Route the control cable from the SmartCool head unit through the mounting bracket, and then below the head casting.
...
Route the Cables
Cable routing varies based on your machine.
...
Slowly jog the spindle head up and down to verify that the control cable is free of obstruction from the machine movement.
Move the Flood Coolant Bracket
If you have an (optional) ATC installed, the coolant hose mount bracket is already relocated. Go to Step 5 of this section.
(Optional) If you have a flood coolant kit installed, remove the 1/4 in. coolant hose and coolant hose mount bracket. Then, set both aside.
...
Attach the relocation bracket to the head casting in location that you identified in Step 2.
Remove the push-to-connect fitting from the tube. Then, install it on the coolant hose adapter with an adjustable wrench.
...
Make Coolant Connections
SmartCool units are pre-configured for use with flood coolant, but you can configure them to use mist coolant as the primary coolant source.
...
NOTE: SmartCool can be plugged in and used at any time. The machine doesn’t need to power cycle for PathPilot to recognize SmartCool.
Calibrate the Height of the Coolant Flow
Using a tool of a known length, calibrate the height of the coolant flow from SmartCool by issuing a M08 or M07 command in PathPilot and mechanically adjusting the assembly installation on the spindle head casting.
Put a measured tool into the spindle and activate its length offset.
From the PathPilot interface, in the MDI Line DRO field, type M8 P0 to turn on flood coolant. Then, aim the stream at the tip of tool.
For information, see "Programming".
Watch the coolant stream: if necessary, adjust the SmartCool head unit within the mounting bracket to visually correct for uneven mounting. Adjust until the coolant stream is in line with the tip of the tool.
...
E~ Adjusts the Z position when using Z0 mode to aim target point of coolant stream.
P~ Defines the target point of coolant stream. The P word is optional; if the P word is omitted, the target point of the coolant stream is the Z0.
R~ Enables oscillating coolant stream (wiggle mode).
Q~ Enables pulsing of M07 or M08 solenoid in seconds. Requires SmartCool Multi-Cool Module (PN 37168).
Examples
To turn on flood coolant, program M08 P~ R~ E~

Cause: Unplugged or defective USB cable | |
Probability | How-To Steps |
High | Verify that the USB device is detected on the Status tab of the PathPilot interface. On the controller, verify that the USB cable is plugged in. If it is, move it to any other open USB port. Verify that the USB device is detected on the Status tab of the PathPilot interface. If it's not, replace the USB cable. |
Cause: Loose pins on control cable | |
Probability | How-To Steps |
High | Verify that all three pins at the control module end of the control cable are seated. If any pins are not seated, click them into place. If the pins don't hold, replace the control cable. |
Cause: Over-tightened hub | |
Probability | How-To Steps |
High | Listen for a sound from the SmartCool head unit that indicates it's working. Verify that the SmartCool head unit doesn't move. Remove the cap from the hub on the front of the SmartCool head unit. Loosen the mounting screws on the hub and replace the cap. |
Cause: Power supply is defective | |
Probability | How-To Steps |
Medium | Remove the cover from the control module and inspect the LEDs on the control board. If the LEDs aren't illuminated, replace the 12V power supply. Reinspect the LEDs on the control board. If the new 12V power supply doesn't illuminate the LEDs, replace the control module. |
Cause: Loose wires from SmartCool head unit to control cable | |
Probability | How-To Steps |
Medium | Remove the back cover from the SmartCool head unit, and inspect the wiring to the control cable. Verify that the connections are firmly seated. |
Cause: Control cable is defective | |
Probability | How-To Steps |
Low | Inspect all three pins at control module end of control cable. If the pins are damaged, replace the control cable. |
