Introduction
1.O INTRODUCTION
Congratulations! Your ProtoTRAK MX2 is a unique, one-of-a-kind, control system
which combines the simplicity of manual machining with the contouring capability of
CNC controls.
The ProtoTRAK MX2 has been designed to maximize the interplay between manual
and automatic machining.
..
.
It acts like an advanced digital readout in manual machine operation.
It acts like a CNC when programmed to do complex contouring jobs.
And it acts with the best qualities of each when your job is best done by
transitioning back and forth between manual and contouring CNC operations
with the powerful DO ONE routines.
Section 2 of this manual provides a brief description of the ProtoTRAK MX2.
Section 3 defines some terms and concepts useful in learning to program and
operate the ProtoTRAK MX2.
The ProtoTRAK MX2 is organized into seven Modes of operation which are described
in the following sections.
Section 4 DRO: Digital Readout, jog, powerfeed, and simple DO ONE CNC
operations.
Section 5 PROGRAM: All input in simple machinist language.
Section 6 EDIT: Program review and edit.
Section 7 SET UP: Tool information and part graphics.
Section 8 RUN: Machining the part.
Section 9 MATH HELP: Sophisticated routines to automatically calculate points
of intersection, tangency, etc.
Section 10 PROGRAM INIOUT: CADICAM interface, and program storage and
retrieval

Turning on the ProtoTRAK MX2
Turn the ProtoTRAK MX2 System on by moving the on-off toggle switch
on the display pendant back panel to the up position.
The display will read "Loading MX 2" indicating that the system's operating
software is being loaded from its floppy disk to its internal memory. This
loading takes about one minute. When complete, the screen will show:

HELP
PROG
INIOUT
> SOFT KEYS
Select the Mode of operation by pressing the soft key beneath the labeled
box.
It is recommended that the system be turned on once each day (if needed)
and then turned off at night. However, the consequence of leaving the
system on continuously is minor.
If the system is not used (either by a key stroke or by counting) for 20
continuous minutes, the CRT will turn itself off. Press any key to bring
the screen back to its previous display. The key you press will be ignored
except to turn the screen on.
Note: Whenyou turn the ProtoTRAK MX2 o& always wait a fav seconds before
turning it back on.

Definitions, Terms & Concepts
3.0 DEFINITIONS, TERMS &
CONCEPTS
3.1
ProtoTRAK MX2 Axis Conventions
X Axis: positive X axis motion is defined as the table movirrg to the left
when facing the mill. Consequently, measurement to the right is positive on
the workpiece. See the figure below.
Y Axis: positive Y axis motion is defined as the table moving toward you.
Measurement toward the machine (away from you) is positive on the
workpiece. See the figure below.
Z Axis: positive Z axis motion is defined as moving the quill up.
Measurement up is also positive on the workpiece.
I
3.2
Absolute & Incremental Reference
The ProtoTRAK MX2 may be programmed and operated in either (or in a
combination) of absolute or incremental dimensions. An absolute reference
from which all absolute dimensions are measured (in DRO, Do One, and
program operation) can be set at any point on or even off the workpiece.
To help understand the difference between absolute and incremental
position, consider the following example:
?- I

3.3
Definitions, Terns & Concepts
Referenced and Non-Referenced Data
Data is always loaded into the Proto'rRAK MX2 by using the INC SET or
ABS SET key. X, Y, Z positions are referenced data. In entering any X, Y,
or Z position data, you must note whether it is an incremental or absolute
dimension and enter it accordingly. All other information (non-referenced
data), such as tool diameter, feedrate, etc. is not a position and may,
therefore, be loaded with either the INC SET or ABS SET key. This manual
uses the term SET when either INC SET or ABS SET may be used
interchangeably.
3.4
Tool Diameter Compensation
Tool diameter compensation allows the machined edges shown directly on
the print to be programmed instead of the center of the tool. The
ProtoTRAK MX2 then automatically compensates for the programbed
geometry so that the desired results are obtained.
If the cutter in the sketch above is moving from left to right from point
X I , Y1 to X2, Y2 and on to X3, Y3, these actual points can be programmed
instead of the center of the cutter.
Definitions, Tenns & Concepts
Section 3.0
Or, for the sketch above, the actual desired circle with radius R can be
programmed instead of the radius of the center of the cutter Rc.
Tool cutter compensation is always specified as the tool either right or left
of the workpiece while looking in the direction of the tool motion. Following
are examples of tool right:
Examples of tool left are:
Tool center means no compensation either right or left. That is, the
centerline of the tool will be moved to the programmed points.

Definitions, Terms & Concepts
Connective Events
Connective events occur between two milling events (either Mill or Arc) when
the XI Y, and Z ending points of the first event are in the same location as
the XI Y, and Z starting points of the next event. In addition, the tool offset
and tool number of both events must be the same.
3.6. Conrad
Conrad is a unique feature of the ProtoTRAK MX2 that allows you to
program a tangentially connecting radius between connective events, or
tangentially connecting radii for the corners of pockets and frames without
the necessity of complex calculations.
For the figure below, you simply program a Mill event from X I , Y1 to X2, Y2
with tool right offset, and another Mill event from X2, Y2 to X3, ~3'alsowith
tool right offset. During the programming of the first Mill event, the system
will prompt for Conrad at which time you input the numerical value of the
tangentially connecting radius (r=k). The system will calculate the tangent
points T1 and T2, and direct the tool cutter to move continuously from X I ,
Y1 through T I , r=k, T2 to X3, Y3.
For the figure below, you program an Arc event from X1, Y1 to X2, Y2 with
tool offset left, and another Arc event from X2, Y2 to X3, Y3 also with tool
offset left. During the programming of the first Arc event, the system will
prompt for Conrad at which time you input the numerical value of the
tangentially connecting radius r=K3. The system will calculate the tangent
points 1'1 and T2 and direct the tool cutter to move continuously from X I , Y1
through T I , r=k3, T2 to X3, Y3.
Section 3.0
Definitions, Terms & Concepts

CONRAD
Note: Conrad must always be the same as or larger than the tool radius for inside
corners. Ifconrad is less than the tool radius, and an inside corner is machined,
the ProtoTRAK MX2 will ignore the Conrad.

At any time during manual DRO operation you may automatically move the
table to your absolute zero location in X and Y by pressing the RETURN
ABS 0 soft key. When you do, the conversation line will read "Check Z then
press GO." Make sure your tool is clear and press the GO key. When you
do, the servos will turn on, move the table at rapid speed to your X and Y
absolute zero position, and then turn off. You will be at zero and in manual
DRO operation.
4.14 Teach
The Teach function allows you to input a program into the ProtoTRAK MX2 by
remembering rapid position and feedrate milling events as you machine the first
part, or portion of a part.
This can be useful for simple operations like facing off a part, clearing out
excess material, or remembering a few hole locations. While Teach can be
useful, it is definitely not a substitute for programming the ProtoTRAK MX2 (see
Section 5) which is very simple, very powerful, and much more useful.

4.14.1
Making a Teach Program
Only one Teach program can be contained in the ProtoTRAK MX2 at any given
time. If an existing Teach program is not first erased (see Section 4.14.3), more
"teaching" will simply add events or moves on to the end of the existing
program.
Teach programs are made up of Position events, or moves, and Mill events.
Position events are moves at rapid speed and are used to go to the beginning
point of a milling move, or to position over a point like a hole for drillirlg. Mill
events are straight line milling moves in the X or Y, or both directions at an input
feedrate.
To make a Teach program, follow these procedures:
a) The first event must be a Position move. Crank the X and/or Y handles to
the desired position and press the SAVE POSN soft key. This point will be
memorized. During Teach Run the machine will move at rapid speed to this
location and stop.
20 1 Section 4.0
DRO Mode
b) If you wish to rapid to the next location, repeat Step a. If you wish to feed or
mill, go to Step c.
c) Mill the part along the X or Y (or both) path using the hand cranks. It's not
important how you get to the end point. In Teach Run the machine will
move at the programmed feedrate in a straight line from the beginning point
to the end. When at the end point, press the SAVE MILL soft key. The
conversation line will prompt "Feedrate 10.0." You may change the feedrate
from the 10 inches per minute default to any value you wish through the
numeric keyboard. When the feedrate is what you want, press INC SET or
ABS SET to load into memory this position and feedrate.
d) Repeat (a) or (c) above for all other rapid Position events, or feed Mill events
you wish.
e) In Teach Run the machine will continue from one Mill event directly along to
the next Mill event. You must program a SAVE POSN if you want the
machine to stop.
f) All events will automatically be saved with Tool Number 99.
g) All Mill events will be saved with TOOL Center Offset (see Section 3.4).
Running a Teach Program
A Teach Program may be run by itself from the DRO Mode, or added to a
regular program (see Section 6.6), and run in the normal Run Mode.
To run a Teach program, press the RLlN TEACH soft key from the screen in
Section 4.14 above. Follow the same procedures for running a regular program
as described in Section 8.3.
Note: Whenyou use Position to go to the beginning of a Mill move, you will have to hit GO
twice to begin the milling move.
4.14.3
Erasing a Teach Program
The ProtoTRAK MX2 may contain only one Teach Program. To input another,
you must first erase the one that exists.
To do so: Press the ERASE TEACH soft key from the screen in Section 4.14,
then select the YES soft key.

Press MODE, select PROGRAM soft key. For a new program to be written,
there cannot already be a program in the active or current program memory.
If a program does not already exist when you enter the Program Mode, the
conversation line will read "Program Part Number." Enter the part number
(up to 8 digits) and press INC SET or ABS SET.
Note: It is not necessary to enter apart number. Ifnone is entered and the INC
SET or ABS SET button is pushed, the system will assume apart number 0.
If there is already a program when the Program Mode is entered, the last
event of this program will appear on the screen. Additional events may be
added after the last event of this program. It will be necessary to erase
this program first before creating a new program. The procedure to erase
a program in order to create a new program is found in Section 6.5. The
procedure to save a program for future use before erasing is found in
Section 10.

Incremental Reference Position
When X and Y data for the beginning position of any event are input as
incremental data, this increment must be measured from some known point
in the previous event. Following are the positions for each event type from
which the incremental moves are made in the subsequent event:
POSITIONIDRILL: X and Y programmed
BOLT HOLE: X CENTER and Y CENTER programmed
MILL: X END and Y END programmed
ARC: X END and Y END programmed
CIRCLE (POCKET or FRAME): X CENTER and Y CENTER programmed
RECTANGLE, POLYGON or IRREGULAR (POCKET or FRAME): X1 and Y1
corner programmed position
SUB: The appropriate reference position for the event prior to the first
event which was repeated.
For example, if an ARC event followed a MlLL event, a 2.0 inch incremental
X BEG would mean that in the X direction the beginning of the ARC event is
2.0 inches from the end of the MlLL event.
5.3
CONRAD
5.3.1 For MlLL & ARC Events
During programming, the ProtoTRAK MX2 will prompt for a CONRAD input
for each MlLL and ARC event. Section 3.6 describes the CONRAD routine
and specifies that to have a CONRAD between two events they must be
connective--that is, the X, Y, and Z at the end of the first event must be the
same as the X, Y, and Z of the beginning of the second, and the tool
compensation direction and number must be the same. When these
conditions are met, the ProtoTRAK MX2 will machine (without stopping)
through the first event, through the connecting radius (CONRAD) and through
the second event.
5.3.2 For Rectangular, Polygon or Irregular Pockets and
Frames
CONRAD has a slightly different meaning within the POCKET and FRAME
Events. It has no meaning for Circular Pockets or Frames. For others,
Section 5.0
Program Mode
CONRAD means "corner radius." This is the radius generated at each of the
corners.
A CONRAD cannot connect a MlLL or ARC into a pocket or frame.
5.4
Continue
In MlLL and ARC events the ProtoTRAK MX2 will ask you to choose Yes or No
to the prompt Continue.
If you want the cutter to keep machining from the event you're programming to
the next event without stopping, you should choose YES. If you want the cutter
X N motion to stop so that you can adjust Z quill position, then choose NO.
If you choose NO, then any programmed CONRAD will be ignored (because
CONRAD assumes you are continuing on to the next event), and in Program
Run the motion will stop.
If you choose YES, then the next event must be a connective event (see
Section 3.5). Prompts for the X Beginning location, Y Beginning location, Tool
Offset, Feedrate, and Tool # will not be asked because, if the events are
connective, this data is already known.
5.5
Programming Strategy and Procedures
The ProtoTRAK MX2 makes programming easy by allowing you to program
the actual part geometry as defined by the print. The Select Event screen
(5.1) is basically a list of all the types of geometry that can be machined with
a two-axis control on a mill.
The basic strategy is to select the soft key event type (geometry) and then
follow all instructions in the conversation line. When an event is selected,
all the prompts which need to be input will be shown on the right side of the
information area. The first prompt will be highlighted and also shown in the
conversation line. Input the dimension or data requested and press INC SET
or ABS SET. For X or Y dimension data it is very important to properly
select INC SET or ABS SET. For all other data either SET will do.
As data is being entered it will show in the conversation line. When SET, the
data will be transferred to the information area, and the next prompt will be

5.12 Subroutine Events
The Subroutine Event is divided into three options: Repeat, Mirror, and
Rotate.
REPEAT allows you to repeat an event or a group of events up to 99 times
with an offset in X and/or Y. This can be useful for drilling a series of evenly
spaced holes, duplicating'some machined shapes, or ever1 repeating an
entire program with an offset for a second fixture. Another use is to repeat a
programmed set of drill events (without offset) so you can center drill, drill,
and counterbore without reprogramming the second and third procedures.
Repeat events may be "nested" five deep. That is, you can repeat a repeat
event, of a repeat event, of a repeat event of some programmed event(s).
One new tool number may be assigned for each Repeat Event.
MIRROR is used for parts which have symmetrical patterns or mirror image
patterns. In addition to specifying the events to be repeated, you h u s t also
indicate the axis or axes (X or Y or XY are allowed) that the reflection is
mirrored across. In addition, you must specify the offset from absolute zero
to the line of reflection. You may not mirror another mirror event, or mirror a
rotate event. Consider the figure below:
O
0.0 I
AWOLUTE
X OFFSET
Holes 1-4 are inirrored across the Y
axis to 5-8, respectively, about a line
X OFFSETQomX=absoIuteO

ROTATE is used for polar rotation of parts which have a rotational symmetry
around some point in the XY plane. In addition to specifying the events to be
repeated, you must also indicate the absolute X and Y position of the center
of rotation, the angle of rotation (measured counterclockwise as positive),
and the number of times the specified events are to be rotated and repeated.
You may not rotate another rotate event, or rotate a mirror event. Consider
the figure below:

events and conrads. Using ROTATE,
these 4 events are rotated through a 45

If you wish to not program an event (or start over) after you have started to
program, press the ABORT EVENT soft key. The screen will show the
"Select Event" screen as described in Section 5.1. Re-select the event
type or another.
5.14 Editing Data While Programming an Event
All data is entered by pressing the appropriate numeric keys and pressing
INC SET or ABS SET. If you enter an incorrect number before you press
INC SET or ABS SET you may clear the number by pressing RSTR
(Restore). Then, input the correct number and press SET.

FWD (Forward) soft key until the incorrect prompt and data are highlighted
and shown in the conversation line. Enter the correct number and SET. The
Proto'rRAK MX2 will not allow you to skip past prompts (by pressing DATA
FWD) which need to be entered to complete an event.
Previous events may be edited in the Edit Mode (see Section 6).
5.15 LOOK
As you program each event, it may be helpful to see what you have done
graphically displayed on the screen. For quick graphics while in the Program
Mode, press the * key located in the upper right area of the keyboard.
This function is active at the end of each event, or whenever the conversation
line is prompting Select Event. Press the * key and the ProtoTRAK MX2
will draw the part in the information area. Note that it will first quickly cycle
through the program to properly size the part to fit the screen. Press RETURN
to bring back the Select Event screen. You may also zoom in and shift the
screen for a better view of a detail. See Section 7.3 for instructions for the
zoom and shift soft keys.
Note: The LOOK routine does not checkfor programming errors. Use DrawPart or
Tool Path (Section 7.3) to check the program.
5.16 Finish Cuts
The Pocket and Frame events are designed with built-in finish cut routines
because they are complete, and stand-alone pieces of geometry. Shapes
machined with a series of Mill or Arc events (either with or without
Continue Mill) don't have an automatic routine for making finish cuts.
There is, however, a very simple technique which can be used.
a.
Program the shape using the print dimensions, and ignore the need to
leave material for a finish cut.
b.
Using a subroutine event, Repeat all the events in "a." but call out a
different tool number.
c.
In Set-Up Mode "lie" about the tool diameter for the tool called out in
events in "a.". Input a tool diameter equal to the actual tool diameter
plus 2 times the finish cut you wish to leave. The ProtoTRAK MX2 will
think the tool is bigger than it really is and, therefore, shift a little
further away from the machined shape.
Section 5.0 ( 42
Program Mode
d.
In Set-Up Mode input the actual diameter for the tool called in the
Repeat event "b.". This will produce the final dimensioned cut.
5.17 Do One Events
The major portion of some jobs can best be done manually with DRO.
However, there are often just a few cuts that require excessive time or
complicated set-up, for example, arcs or diagonals. DO ONE programming
assists you in performing these more difficult operations without the
necessity of complete programs.
DO ONE events may only be programmed and run one at a time. When a
DO ONE event has been run, it is erased from the ProtoTRAK MX2 memory.
The incremental reference position for any DO ONE event is the current
position of the tool (or actually the table and saddle). That is, the position
at the time the event is run. So an incremental input will move the table by
that amount from where it currently is. The absolute reference is unchanged.
DO ONE programming is nearly identical to the complete part programming
described in Section 5, with these differences:
a.
b.
c.
d.
e.
f.
Press the DO ONE soft key in the DRO Mode to activate this routine.
You do not have to program a tool number. Since the program has only
one event, you need only one tool.
You will be prompted for tool diameter during DO ONE programming.
Therefore, you do not need to enter SET UP Mode.
DO ONE Mill and Arc Events will not prompt for CONRAD. There is no
second event to connect to.
There cannot be a DO ONE Subroutine event.
You cannot draw a-DO ONE part or tool path in Set-Up Mode, or with the
* key (see 5.16).
When the DO ONE event is complete, press START to run DO ONE.

7.5.1 Sensor Calibration: Code 123
Occasionally it may be necessary to recalibrate the TRAK Sensor encoder
accuracy. To do so, select the SERV CODES soft key from the screen in
Section 7.1. The conversation line will prompt "CODE." lnput 123 and press
SET. The procedure is as follows:
a.
b.
c.
d.
The conversation line prompts "Select Axis." Press X, or Y, or Z.
The conversation line prompts "Move to Standard Begin, then SET." Place
a dial indicator in the spindle and move the table to touch off one end of a
standard or piece of material of known length. Press SET.
The conversation line prompts "Move to Standard End, then SET." Move
the table to touch off the other end of the standard. Press SET.
The conversation line prompts "lnput standard length, then SET." lnput the
length of the standard and press SET.
If a legitimate calibration is computed (actual divided by standard length), the
system will automatically abort to the SET UP mode of operation. Repeat
the entire procedure for each axis to be calibrated. If the calibration is not
legitimate, the display will read "Unreasonable Calibration Factor" This occurs
if the displayed readout in the calibration procedure was less than the standard
length, or too much (the maximum allowable is 1% more than the standard).
Verify the standard, repeat the procedure, and request SWI or distributor
service if needed.

Press the SERV CODES soft key from the screen in Section 7.1.
Press 33 SET when the conversation line prompts "CODE". The
software identification will be shown in the Information area of the
screen.
7.5.6 Program Scale Factor
Use this Scale Factor Code if you wish the part you are making to be larger
or smaller than the dimensions you program. For example, if you program
2.0000" by 3.0000" pocket and input a Scale Factor of 1.03, the pocket will
be machined 2.0600" by 3.0900". A .97 Scale Factor would produce a
1.9400" by 2.9100" pocket.
The default Scale Factor is 1.0000. This produces no change from the
programmed data.
To input a new Scale Factor use the following procedure:
a.
b.
c.
Press the SERV CODES soft key from the screen in Section 7.1.
Press 14 SET when the conversation line prompts "CODE".
Input the Scale Factor value (from .I000 to 10.0000) and press INC SET.

In the RUN mode the status line will show "S/FUwhenever the Scale Factor is not set
at 1.0000.
7.5.7 Irregular Pocket Stepover
In Irregular Pocket run, each machining pass cuts material equal to 71 percent
of the tool diameter (this transfers into nearly 100% at certain corners). This
represents a maximum cut or stepover.
This maximum stepover may be reduced by a factor from 1.0 (no change) to
0.1 (10 percent of the maximum). To input a new factor, use the following
procedure:
1 56

b) Press 140 SET when the conversation line prompts "CODE".
c) Input the new stepover factor and press INC SET.
7.5.8 Save Calibra1:ion Constants to System Disk
Calibration constants (for sensors, ball screws, etc.) and certain system
configuration data are stored in the ProtoTRAK MX2 computer EEPROM
memory chips. This Service Code allows you to copy these parameters to
your system disk. The value of this is that if you have a computer module
failure, your serviceman can copy the parameters from the disk back into the
corrected computer memory without recalibrating the entire machine tool.
To save the calibration constants to the system disk, use the following
procedure:
a) Press the SERV CODE soft key from the screen in Section 7.1.
b) Press 142 SET when the conversation line prompts "CODE".
c) Read the instructions and press the YES soft key if you wish to execute

Starting to Run
Before running a part, you need to establish the position relationship
between the part and quill. That is, you need to identify where the part is
on the table relative to the tool or quill centerline.
This is done by using an edge finder or dial indicator to move the table so
that the part program absolute zero is under the quill centerline. SET this
position as absolute zero in the DRO mode.
The program may be started in the two ways identified as soft keys in the
screen in Section 8.1
Pressing the START soft key begins the program at Event 1 and assumes
that the absolute zero that was last set in the DRO mode corresponds to the
part program zero. That is, if you were in the DRO mode and you moved the
table to X=O ABS, and Y=O ABS the part program zero would be directly
under the quill centerline. This start does not reset your absolute zero.

Stop
At any time, the program may be halted by pressing the STOP key. This
freezes the program at that point. To continue, press the GO key.
8.6
Feedrate Override
The run feedrate may be changed at any time by pressing the FEED 'b or
FEED J, keys. Each press changes the programmed feedrate, as well as
rapid by 10%.
8.7
Trial Run
Trial Run allows you to quickly check out your program before you actually
start to make parts. In trial run the table will move at rapid speed regardless
of what feedrates are programmed (the rapid speed may be overidden with
FEED 'b and FEED J, keys). The table will stop at each "stop" location (for
example, at each drill location) but immediately continue on without your
input.
To do a trial run, press the TRIAL RUN soft key from the screen shown
in Section 8.1. The conversation line will read "Check Table and Z, then
press GO." Be certain the table is positioned so that if it moves through the
part program, it will not reach its travel limit. Also check that the quill is fully
retracted. Press GO to begin.
8.8
Data Errors
The Program Mode in Section 5 describes several rules which must be
followed to successfully program a part. In addition, a program must make
sense geometrically. For example, you can't machine a .250 inch diameter
circular pocket using a .500 inch end mill.
Data errors will nearly always be detected when the ProtoTRAK MX2 runs
through a program--either as a Trial Run or on an actual part run. They may
often be detected in the Set Up mode when using the Draw Part or Tool Path
Graphics routines.
Whenever the ProtoTRAK MX2 detects a data error the display will change to
a screen typified by the example below.

PROGRAM INlOUT MODE
You may store and retrieve programs in three different ways:
1. The ProtoTRAK MX2 has a built-in floppy disk drive which can store 30
to 50 moderate size programs. The disk cannot be changed, so once it
is full some programs will have to be erased before others can be added.
2.
You may purchase a 3.5 inch portable floppy disk drive system from
Southwestern Industries which interfaces to the Proto'rRAK MX2. This
portable system plugs into the ProtoTRAK computer and can be used to
service several ProtoTRAK MX2's. Each separate disk will store up to
96 moderate size programs. The disk from your computer (see 3 below)
which holds the ProtoTRAK programs may be used with the portable
floppy disk drive system and vice-versa.
3.
You may store and retrieve programs through an RS232 link to most
computers. The RS232 port is located on the back of the pendant box.
This same link is used to load programs which have been written via a
CADICAM system.
All programs are transmitted through the ProtoTRAK MX2's current or computer
program memory. Programs are sent from the computer memory (that is, a current
program) to one of the above three permanent memory locations. Or programs are
retrieved from one of the three, and loaded into the ProtoTRAK MX2's computer
memory. Programs may not be sent directly from one of the above three storage
devices to another.
10.1 Cautions About Storiog and Retrieving Progranis
Care must be taken to keep from losing a program you wish to keep. This
can happen two ways.
First, whenever a program is retrieved, it is loaded into the ProtoTRAK
MX2's computer program memory. When this happens, your existing current
program is erased. Therefore, if your current program is one you want to
keep, be certain to store it before you retrieve another program.
Second, to store a program it must have a part number so that the ProtoTRAK
MX2 can find it if you want it retrieved. However, no two programs can have
the same part number (how would the system decide which to retrieve?).
Therefore, if you store a program with any particular part number, it will
automatically erase any other program with that same part number.
74 1 Section 10.0
Program In/Out Mode
10.2 Program Formats And Labeling
The ProtoTRAK MX2 has its own unique programming system--one that
organizes the program into events rather than codes and blocks. Most
CADICAM sytems output their programs in an RS274 format--commonly
referred to as a G-code format.
The ProtoTRAK MX2 software will accept an RS274 CADICAM generated
program (as configured through a Fanuc 6 post processor) and convert it to
an MX2 event type program. 'This can occur by directly downloading the
program through an RS232 connection from your personal computer to the
ProtoTRAK MX2 (see Section 10.6) or by transferring your personal computer
floppy disk to an optional portable floppy drive and then loading it into the
ProtoTRAK MX2 (see Section 10.5).

10.5 Storing and Retrieving Programs from the Optional Portable
Floppy Disk Drive
The portable Floppy Disk Drive plugs into the computer cabinet (see
Figure 3).
Select the Portable Floppy option by pressing the PORT FLOPPY soft key
from the screen in Section 10.3. The screen and procedures are nearly
identical to those for the ProtoTRAK MX2 built-in floppy disk in
Section 10.4. The differences are:
a.
The Status line will read "PROG INIOUT PORT FLOPPY".
b.
Press the RETRVE MX2 soft key if the program you wish to retrieve is in
the MX2 event type format (it will be labeled MX2 on the screen listing).
c.
Press the RETRVE CAM soft key if the program you wish to retrieve is in
the CADICAM, RS274, G-code format (it will be labeled CAM on the
screen listing).
Be certain that the portable system is plugged into the ProtoTRAK MX2
computer cabinet before you select the PORT FLOPPY soft key from the
screen in Section 10.3. You will get an error message if it is not.
Note: Ifyou write a program using a CAD/CAM system with a Fanuc 6
postprocessor on your computer and intend to enter it into the ProtoTRAK MX2 via
the portable floppy drive, you must name the program with one to eight numerical
digits followed by a decimal point, followed by CAM for example, 123.CAM or
87654321.CAM). Ifthese rules are not followed the MX2 will not recognize the
program.
