5. Loading a Workpiece for Cutting

To load workpiece, use the adhesive sheet or clamps included with the machine.
When performing engraving that subjects the workpiece to a load, use the clamps to secure the workpiece in place. When engraving the
edge of the workpiece or when loading a workpiece with a thickness of 10 mm (25/64") or more, use the adhesive sheet.
Large-size material (i.e., material that is about the same size as the PNC-2300's table) cannot be affixed to the table securely using the
adhesive sheet or clamps. In such cases, use commercially available double-sided tape to secure the workpiece in place.
* A vacuum table (ZV-23A) and a center vise (ZV-23C) are optionally available and should be purchased if needed.

Loading Workpiece Using the Adhesive Sheet

Place the adhesive sheet on the table and press it
down.

1

Place the workpiece to be cut on the adhesive sheet
and fasten it while pressing down.

2

Do not attempt to wash the adhesive sheet with water. Doing so will damage the adhesive surface and make it impossible to grip
the material.

Part 1

When Using the Depth regulator nose

Using the depth regulator nose makes it possible to engrave even workpiece of non-uniform thickness at the same depth.

Rotate than depth regulator nose in the direction of the
arrow 2 in the figure to tighten it completely.

1

This determines the engraving depth (cutting-in
amount). The scale on the micrometer dial assembly
has 25 grooves, with one groove corresponding to an
engraving depth of 0.025 mm (1/1000"). (One full
turn of the scale corresponds to an engraving depth of

0.625 mm.) Rotate the scale in the direction of the
arrow shown in the figure by an amount equal to or
greater than the engraving depth.
For example, when engraving to a depth of 0.5 mm,
the scale should be rotated by 20 grooves or more
(approximately one full turn). For engraving at a
depth of 1.5 mm, rotate the scale by 60 grooves or
more (approximately three turns).

Part 1

Item Characteristics/Points to Consider

The bigger this number, the faster the cutting speed. However, if this number is too large, the work
surface may melt or burn due to excessive friction. Conversely, if this number is made smaller, the time

Spindle motor taken for cutting becomes too longer. Generally speaking, the entire cutting speed is determined by the

revolution speed cutting edge speed, so the smaller the tool diameter, the higher the spindle revolution speed required.

(When performing engraving without rotating the cutting tool, set “REVOLUTION” to “OFF.”)

Revolution speed : 5,000—15,000 rpm

When the feeding speed is high, processing becomes rough and flash marks tend to remain on the cut

Feeding speed surface. On the other hand, when the feeding speed is slow, processing takes more time.

Be careful because a slower feeding speed does not always result in improved finishing.

When the cutting-in amount is deeper, the cutting speed increases, but the cutting-in amount is limited

Cutting-in amount by the quality of the workpiece. In cases where the required depth can not be cut at once, repeat cutting

several times to depth that does not breach the limit.

9. Cutting Condition Setting

Before you begin the actual cutting process, the cutting conditions such as the revolution speed of the spindle motor and the feeding
speed of each axis must be designated according to the quality of the workpiece and the type of cutter used. There are several deciding
factors to be taken into account when designating the cutting conditions.

1. The quality of the workpiece 4. The cutting method

2. The type of cutter used 5. The cutting shape

3. The diameter of the cutter used

Designate the cutting conditions in consideration of the above factors by performing the following three PNC-2300 setting operations.

1. The spindle motor revolution speed (cutter revolution speed)

2. The feeding speed (cutter moving speed)

3. The cutting-in amount (depth of one cutting operation)

Note : When settings have been made with both the software and the PNC-2300, the last settings made have

priority.

In this manual, these three conditions are called the cutting conditions. The characteristics and points to consider for each of these
conditions are as follows.

Manual Setting of Cutting Conditions

The cutting conditions can be set manually according to the method described below.
If the cutting conditions can be set with your current software, this is a faster and more efficient method than manual setting. It makes no
difference when you come to construct a program. The following method is appropriate for making delicate halfway adjustments to
conditions previously set using software, etc.

Press the [MENU] key to make the following screen
appear on the display.

Cutting Condition Setting Examples

The chart below contains reference examples of the appropriate cutting conditions for several types of workpiece material. In the case
that the conditions are input using software or when constructing your own programs, set the cutting conditions with reference to the
chart. However, because conditions differ depending on cutter sharpness and workpiece hardness, cutting performance may not always
be optimal when adhering to the conditions specified below. In such a case, delicate adjustment should be performed at the time of actual
cutting.

User's Reference

Cutting Area

The maximum cutting area of the PNC-2300 is 305 mm 230 mm 30 mm (12" 9" 1-1/8"). When converted to coordinate
values, this corresponds to (x, y, z) = (30500, 23000, 3000) when the coordinate unit is 0.01 mm, or (x, y, z) = (12200, 9200, 3000) when
the coordinate unit is 0.025 mm. Changing the coordinate unit causes only the coordinate units for the X and Y axes to change. The
coordinate unit along the Z axis is always 0.01 mm/step.
The actual available cutting area is subject to restrictions according to the length of the attached cutter and the workpiece height; and in
some cases it may be larger than the maximum operating area.

settings match the settings for the com­puter?

Is the power for the PNC-2300 switched on?
Has the connection cable come loose?

Is the correct connection cable being used?

Is the correct output device set for the
application or driver software?

The PNC-2300 will not operate when the cover is open. Close the
cover and try again.

If the [ENTER/PAUSE] key is pressed while the machine is in
operation, the message “Pause On” appears on the display and
operation is paused.
Choose “CONTINUE” and press the [ENTER/PAUSE] key again
to cancel the paused state.

Refer to “Setting the Connection Parameters” on page 6 to make
the correct settings.

Make sure the PNC-2300 is powered up.
Make sure the connection cable is plugged in securely with no
looseness at either end.

The type of connection cable varies according to the computer
being used. Also, some application software requires the use of a
special cable. Make sure the correct cable is being used.

Refer to the manual for the application or driver software to set the
output device correctly.

When the PNC-2300 does not work...

Is “REVOLUTION” set to “OFF?”

If “REVOLUTION” is set to “OFF,” the spindle will cut without
rotating.
Refer to page 26 and change the setting for “REVOLUTION” to
“ON.”

When the spindle does not rotate ...

The power does not come on...

Is the EMERGENCY STOP switch set to
STOP ( )?

Has the power cord come loose?

If the EMERGENCY STOP switch has been depressed, the power
will not come on when the power switch is turned on.
Refer to page 3 to set the EMERGENCY STOP switch to RE-

LEASE ( ).

Make sure the power cord is plugged in securely with no looseness
at either end.

Cutting depth varies in places (deep and shallow cuts)

Is the workpiece flexing?
Is the workpiece height uneven because of

the double-sided tape used for securing it
was stuck on poorly?

Check the setting and clamping of the workpiece.

Check how well the material is secured and reload it.

*

Cutting to the same depth, even of workpieces of different thicknesses can be done if the depth regulator nose is used.

If you want to completely stop the operation of the PNC-2300, turn off the power switch.

31

Part 2

Cutting line varies in places

Is the workpiece vibrating because the
adhesive double sided tape was stuck on
poorly?

Check where the double-sided tape is affixed and reload the
material.

Engraving cannot be performed at the desired location

Is there a mistake in the home position
setting?

Was there a position error when the
workpiece was replaced?

Refer to page 12 of “Setting the Origin (Home Position)”. Use
these procedures to set the home position correctly.

Check that workpiece position setting is correct.

The letters have been cut too deep (or too shallow) and cannot be read

Is the cutter mounted securely?
Is there a mistake in the Z position?

Refer to “Loading a Cutter” on page 8 to install the cutter securely.

Increase (or decrease) the “Z1” setting as needed.

When moving the cutter while in the up position the cutter tip contacts or pulls on the workpiece

Is there a mistake in the Z position? Refer to page 16 of “Setting the Z1 and Z2 Position”. Increase the

“Z2” setting as needed.

Burrs are present on grooves made during cutting

Is the cutter mounted securely?
Is the tip of the cutter worn?
Is the cutter feed speed too fast (spindle

rotation speed too slow).

Refer to “Loading a Cutter” on page 8 to install the cutter securely.

When the tip of the cutter is worn, replace with a new one.

Refer to page 13 of “Feeding Speed” to find the correct feed speed
“XY-SPEED” and “Z-SPEED”, and adjust the spindle rotation
speed by referring to page 14 of “Spindle Motor Revolution
Speed”.

The cutting finish is unsatisfactory

Separating the process of cutting the material into two stages makes for engraved results which are more attractive. After
rouging out the general shape with “rough engraving,” “finishing” is performed to produce the final results.
For instance, to cut letters to a depth of 0.3 mm, first of all rough cut to a depth of 0.25 mm. Then continue exactly the
same kind of cutting to a depth of 0.3 mm.

Part 2

Error Messages

An error message will appear if incoming data has any of the errors listed in table. Since the error is shown in the display for informational
purposes, the data transfer continues and you are allowed to perform the next operation.
To get the error message to go away, press the [MENU] key.
Note that even though the error message is no longer displayed after you press the [MENU] key, the PNC-2300 will retain in memory the fact
that the error occurred. To clear the error internally, you can give the default instruction, IN; or the error code output instruction, OE. (The
error can be cleared by turning the power off.)

Meaning

Appears if an instruction that the PNC-2300 cannot interpret is sent. This error is generated if an
instruction from the “mode2” set is sent when the unit has been set to recognize “mode1,” or
viceversa. Change the setting for the recognized instruction set, using the control panel, and this error
should no longer occur.

Error message

Appears if the number of parameters differs from the permissible number.

Appears if the value specified for a parameter is out of the permissible range.

Appears if an unusable character is specified.

Appears if an output instruction is sent from the computer during execution of a previous output
instruction. More precisely, there is a certain amount of delay between the moment an output
instruction is given and the instant actual output begins. This error message appears if the new output
request arrives during this delay time. (The delay time can be set using the [ESC].M instruction.)

Appears if a device control instruction that the PNC-2300 cannot interpret is sent.

Appears if an invalid parameter has been specified for a device control instruction.

Appears if the value for a device control instruction parameter exceeds the permissible limit.

Appears if the number of parameters for a device control instruction is more than that permissible.

Appears if a framing error, parity error, or overrun error occurs at the time of data reception. (There
is a problem with one of these settings: Baud Rate, Parity, Stop Bits, or Data Bits. The protocol
settings for the PNC-2300 must be made correctly in order to match the settings your computer is set
to use.)

Appears if the I/O buffer has overflowed. (There is a problem with the connecting cable, or the
settings for Handshaking. Make sure you are using a cable appropriate for the computer being used.
Also, check that the setting for Handshaking is correct.)

Appears if the polygon buffer is full.

Appears if an indeterminate communication error other than the I/O errors described above has
occurred.

33

Part 2

Other Messages

Besides error messages related to commands or communication parameters, the following messages may also appear on the display.

Message Meaning

This message appears if repeat cutting is attempted when the cutting data exceeds 1 MB. The data
cannot all fit in the PNC-2300's data buffer, so repeat cutting cannot be performed.

This message appears if cutting is attempted while the cover is open.

This message appears if repeat cutting is attempted when the data buffer is empty. Send cutting data
before performing repeat cutting.

The PNC-2300 stops automatically if an excessive load is placed on the spindle during cutting. The
message shown at right appears at this time. The overload may be due to excessive hardness of the
material, an excessive amount of cutting, or a feed rate that is too fast. Investigate the problem and
eliminate the cause of the overload.
The error can be cancelled by switching the power to the unit off and then on again.

If the cover is opened during cutting, an emergency stop is performed and this message appears. All
cutting data stored in the PNC-2300 is deleted, and cutting cannot be continued.
If this message appears, stop sending data from the computer. Switch the power off and back on
again to cancel the error.

A message may be displayed indicating that buildup of cuttings has obstructed table movement.
Clean away all cuttings from around the table.
Switch the power off and back on again to cancel the error.

DTR signal to High without performing the
hardware handshake. An odd number parameter
(e.g. 1) performs the hardware handshake and
controls the DTR signal according to the remaining
buffer capacity.

Status Instructions

ESC .O [ESC].O None Outputs the status codes of PNC-2300 shown in
Outputs the Status the table below.
of Buffer, Pause

Code Meaning

0 Data remaining in buffer.
8 Buffer empty.

16 Data remaining in buffer. PNC-2300

being paused (Pause On being displayed).

24 Buffer empty. PNC-2300 being

paused (Pause On being displayed).

Device Control Instructions

The Device Control instructions determine how communication between the PNC-2300 and the computer will be handled using the RS­232C interface; and also are employed when relaying to the computer the status of the PNC-2300. Some of them can be used to format
the output for CAMM-GL I instructions.
A Device Control instruction is composed of three characters: ESC (1Bh), a “.”, and an uppercase letter. There are also two types of
device control instructions: one carries parameters and the other does not.
Parameters can be omitted. Semicolons, “ ; ” are used as separators between parameters. A semicolon without parameters means that
parameters have been omitted. Device Control instructions with parameters require a terminator to indicate the conclusion of the
instruction. A colon “ : ” is used as the terminator, and it must not be omitted.
No terminator is necessary for Device Control instructions without parameters.

Error Possible cause
code and action

0 No I/O errors

10 Cause: after execution of an output

command, other output instructions are
sent before the output was not completed.
Action: let the computer to read the PNC­2300 output by the output instruction
and then send another output instruction.

11 Cause: an error occurs in a device

control instruction.
Action: correct your program.

13 Cause: parameters are overflowing.

Action: correct your program.

14 Cause: the number of the parameters set

is more than specified or a colon ':' was
not used to terminate.
Action: correct your program.

15 Cause: framing error, parity error or over-

run error at the time of data receipt .
Action: match the communication
protocols of both computer and PNC­2300 (baud rate, data bit length,
stop bit length).

16 Cause: the I/O buffer overflows.

Action: This error does not occur when
hardware handshake is performed, but
may occur when software handshake is
performed. If this error occurs, check the
remaining buffer capacity of the PNC­2300 and send less data than the
remaining buffer capacity.
