Introduction:
At the end of this document is an addendum that provides both the definition and a short description
of the long list of ‘keywords’ used in CNC and also in General Digital Communications.
It is not necessary to understand all of the terms used in this document since each task is presented
with the specific information you will need to provide and also the specific points where you need to
enter that information.
For those who would like a better understanding of the underlying processes provided by the device
they are installing as well as the device they are installing it on, each technical term that is blue in the
text will have a corresponding definition and brief description in the addendum. Often, only this little
bit of extra information can make a mysterious topic far more comprehendible.
The InTurn™ 4th axis Motor Control System is designed specifically to provide Mill/Turn capabilities
for Mach3 and Mach4 CNC control Software for any CNC mill.
Mill/Turn is a capability of high-end Machining Centers that have a starting price tag around
US$100,000, so it is a very significant achievement to bring some of those capabilities to an existing
benchtop of full size CNC mill for under US$5,000.
Mill/Turn requires the 4th axis to have the capability to spin continuously at high speed with a
significant amount of power over a wide range of speeds, and ALSO have the ability to stop spinning
and return to the conventional indexing process. To be useful as a CNC add-on capability, all of this
has to be controllable by the CNC system itself with minimal or no intervention by an operator.
While MACH software provides for indexing on a rotary axis, it has no ability to spin that axis
continuously. The InTurn™ 4th axis Motor Control System adds that basic capability and a lot more,
all controllable both from custom on-screen controls and also via macros embedded in the G-code for
a fully automated CNC process.
So let’s get on with the Installation!
Note: In the text, where the name of a parameter will vary from one system to another, or from one
version to another, the variable portion is represented by ‘placeholders’ using ‘xx’ to represent
numbers and square brackets around a descriptive word like ‘[date]’ to represent the variable part of a
filename or folder name. The actual name will contain the number or date, for example ‘COM10’ or
‘InTurn™Parameter041215.brn’

“Interviews are good if you want to be an actor because they raise your profile.” - Jack Gleeson
MACH3 new PROFILE creation:
Using the MACH ‘loader’ to start MACH, make a new profile by ‘cloning’ whatever profile you are
currently using. Name the new profile ‘InTurn™’.
Close Mach3 and restart using the new profile name. You can do this one of two ways:
1) Start Mach3 by starting the Mach3 Loader program and selecting the InTurn™ profile
2) Create a shortcut that starts Mach3 while automatically using the InTurn™ profile.
To create a Shortcut, follow these steps:
A) Using a RIGHT click and hold, drag the file C:\Mach3\Mach3.exe desktop.
B) On release of the mouse button, you will be presented with choices. Select ‘Shortcut’
C) Locate the new shortcut on your desktop and RIGHT click on the icon
D) Change the parameters to match the following screen shot:
All of your MACH3 settings should be retained in this new profile. Now we will change or add those
that pertain to the new InTurn™ controller and screen set.

Download, UnZIP and Copy Files:
Files are obtained by downloading. Links will be provided via e-mail for new controllers,
updates or upgrades.
Using the provided link, download the zip file and move it into C:\ and then unzip the file.
The files will be unzipped into folders that match the corresponding MACH folder name except that
the names have the prefix ‘InTurn_’ added. The InTurn files can be safely stored in these folders
since MACH does not recognize the folder names and therefore will not overwrite them.
Simply copy the entire contents of the unzipped ‘InTurn_[name]’ folders into the matching Mach
folders. For example, copy all of the files in “InTurn_MillBitmaps” into the \Mach3\Bitmaps\MillBitmaps
folder. Do the same with all of the new InTurn folders that appear after unzipping the file.
In the end, you need to have:
New macros from “InTurn_Macros” into the directory \Mach3\macros\InTurn
Note: Mach has a special macro named ‘HiddenScript.m1s which contains ALL of the macros
associated with the screen controls. This is a reserved name (cannot be changed) so there is no way
to know the version of the macro or what screen it goes with. For this reason, the InTurn™ version is
named ‘HiddenScript[date].m1s’. Do not change the name of this file. Instead, copy the file, for
example ‘HiddenScript012514.m1s’ into the Mach3\macros\InTurn folder and then change the name
of that file by removing the date.
Note: Some versions of MACH3 will unexpectedly overwrite the entire macro folder without warning
or notice. This will stop the InTurn™ from functioning. The remedy is to copy the macros from your
backup; “InTurn_Macros’ into the \Mach3\macros\InTurn folder again and then remove the date
from the name of ‘HiddenScript[date].m1s”.

MACH3 Brain Programs
“Why, I outta BRAIN ya” – the three Stooges
Copy the following from InTurn_Brains into C:\Mach3\Brains
InTurn4thAxis[date].brn
InTurnE-stop[date].brn
InTurnAxisFraction[date].brn
InTurnParam[date].brn
Note: for these brain programs, the date can be left in as part of the file name.
Later, you will activate the brains using the entire name including the date.
“Everyone can do simple things to make a difference, and every little bit really does count.” - Stella McCartney
Screen Bitmaps from “\InTurn_Bitmaps”into “\Mach3\Bitmaps\MillBitmaps”
Note: after copying the files into the above directory, look in the folder and there should be Cube
Studio specific graphics similar to those shown below.
There is one exception to the folder naming convention used in the InTurn™ distribution.
Copy the screen set ‘\InTurn_Screenset\InTurn1920[suffix].set’ into C:\Mach3
Note: The suffix is typically two letters, but in any case, use the actual filename as it
appears in the unzipped folder.

Drivers
“A careful driver is one who honks his horn when he goes through a red light.” - Henry Morgan
A folder named ‘InTurn_Drivers’appears after unzipping;
Install the Arduino Drivers (only if this is a new install)
Plug in the USB cable to any USB port on your computer.
Windows should complain about the new USB device.
Tell windows to look in the folder:
C:\InTurnMotorControllerDist2015-xx\InTurn_Drivers
Note: Bolded numbers are year and rev and may be different than shown.
Windows will find and install the drivers then be happy with the new USB device.
To determine which COM number the driver created, use the following steps
Make sure MACH3 is NOT running.
Power OFF the InTurn™ Controller.
Power ON the InTurn™ Controller.
On the menu bar at the lower left of the WINDOWS screen, click the following sequence:
Start->Control Panel -> System -> Hardware (tab) -> Device Manager (button) -> Ports (COM & LPT)
There should be a ‘Communications Port’ Identified as Arduino Mega and a COM# after it. Write the
port number of your InTurn™ Controller below. You will need it later.
___________ InTurn™ Communication Port Number

Configuring MACH3
“I've always been bossy.” - Shirley Temple
Tell MACH3 to use the new screens:
At the top of the MACH screen click on ‘view’, then ‘load screens’ then navigate to where you copied
‘InTurn1280IY.set’ and select it. The new screen should appear. Close Mach3 and restart it.
Tell MACH3 to use the new Brain Programs:
On the MACH3 screen, click on Operator. Choose Brain Control from the drop down list.
Find ‘InTurn4thAxis[date].brn’ on that list and click on it to highlight it.
If that name does not show up on the list, the file is probably in the wrong place.
Brain programs must be located in the folder . . . \Mach3\Brains
With the name highlighted, click the enable box.
Now do the same with ‘InTurnE-stop[date].brn’
And also with InTurnParam[date].brn
And lastly with InTurnAxisFraction[date].brn
Note: other listings in the window will not be related to the InTurn™.
Now click the OK button. Close Mach3 and restart it.
10
Tell MACH to use the included Macro Pump.
Check the box next to ‘Run Macro Pump’ on this ‘General Configuration’ screen accessed from the
‘Config’ drop down on the main MACH screen.
Add ‘M4444’ to the end of whatever is in the Initialization String.
Note: Mach will only run one ‘M’ code in this String, so if there is already an ‘M’ code, it will either
have to be removed or combined with the M4444 macro.
