The GERBERcutter uses three imaginary lines or axes to tell direction and location on the cutting table. They are the X, Y, and C-axes, as shown below.
If you stand at the operator console, the Y-axis runs across the table, the X-axis goes from left to right, and the C-axis is in the cutter head. The beam moves along the X-axis, the cutter head travels the Y-axis, and the knife turns around the C-axis in the cutter head.
Movement is always in a plus (+) or minus (-) direction on the X and Y-axes. If you stand at the operator console:
+X is to your right. +Y is away from you. -X is to your left. -Y is toward you. C-AXIS Y-AXIS X-AXIS +Y -Y -X +X
Basic Concepts 33
Location is also given in terms of the X and Y-axes, as shown below.
If you stand at the operator console, the point X0, Y0 is at the lower left corner of the work surface, as shown below.
All locations on the work surface are relative to this position. Unlike direction, location is always stated in positive numbers. To find the point (X=24 in., Y=36 in.), start at X0, Y0. Measure 24 in. to the right along the X-axis. From there, measure 36 in. away from you on the Y-axis . You are now at the point X24, Y36.
Origin
Just as the table has a X0, Y0 position marking its lower left corner, so does each cut file/marker. The X0, Y0 position of the cut file/marker is called the origin. All data points (locations) of the cut file/marker are relative to the origin.
Before the GERBERcutter can cut a cut file/marker, you must set the location of the origin. The cutter then cuts each piece relative to this point. The origin is set from the beam control panel or at the operator console (see chapter 3). The
origin light is a red laser light located in the cutter head that shines on the cutting table (see the Safety chapter of this manual).
WARNING! The origin light uses a Class IIIa laser. Do not look directly into the laser beam without protective glasses. Do not place any reflective (shiny) material on the cutting table. Remove watches, rings, and other jewelry. Reflected laser light may cause eye injury. X0, Y0
The origin must be close enough to the lower left corner of the table so that the cut file/marker can fit on the table. For example, the origin shown below is at X25, Y50.
With that origin, the cut file/marker extends off the table in the Y direction. You can correct this situation by moving the origin to X25, Y25.
If the cutter cannot cut the cut file/marker because it will go off the table, you will receive an off table message, such as one of the following:
Off table in +Y Off table in -X
Basic Concepts 35 Using the Check Origin feature, the system automatically verifies that the cut file/marker will fit on the cutting table with the current origin. It does this before cutting the cut file/marker. If the origin will not work for your file, the system displays an error message like this:
Bad Origin: X too high (x.xxx) acceptable range: x.xxx - x.xxx
wherex.xxx is a table location in the X direction. You get a similar message if the origin needs to be corrected in the Y direction.
Bite Feeding
GTxL systems use a conveyor for bite feeding. Bite feeding is a feature that matches cutter head movement with conveyor movement, permitting automatic cutting of a long spread. The GERBERcutter does this by cutting the spread in sections. The marking system sets the length of each section in inches or centimeters as one bite. After the cutter pulls the bite onto the cutting table and cuts it, the conveyor automatically advances, positioning the next bite on the cutting surface.
An example of how the conveyor and bite feeding work is shown on the next page.
Diagram 1 shows a 48.8 m (160 ft.) spread of material that the marker maker has divided into 20 bites, each 2.4 m (8 ft.).
To begin automatic cutting, the conveyor pulls the leading edge of the spread onto the cutting surface with the aid of underlay paper. The conveyor moves until it pulls the first bite onto the cutting table as shown inDiagram 2. The GERBERcutter cuts the first bite, including pieces that extend into the second bite As shown inDiagram 3. The knife cuts a slit in the selvage of the material to mark the origin of the second bite. The slit (or edge clip) made by the marking system is a reference point in case you stop cutting during the second bite.
Next, the conveyor automatically moves the first bite down the cutting table and brings the second bite in position to be cut as shown inDiagram 4. While the bundle handlers are removing the pieces from the first bite, the GERBERcutter begins cutting the second bite.
After the system completes the second bite, the conveyor moves the third bite onto the cutting surface. It brings the second bite down to the bundle handlers, and moves the first bite scrap from the cutting surface to the take-off table, where you can collect or discard it as shown inDiagram 5.

Basic Cutting
Sections in this chapter explain:
• Spreading material.
• Turning the GERBERcutter on and off • Basic cutting on your GERBERcutter
For additional information on how to use C-200MT program features, refer to the C-200MT Software User’s Guide.
Spreading Material
CAUTION: Different materials require specific spreading methods for the best cutting results. Also, spreading requirements are different for
systems without a conveyorized table. The following procedures are general guidelines only.
To spread material on the spreading table
1. Place an underlay of perforated or air-porous paper (25 to 60 lbs.) on the spreading table. Be sure the paper is straight on the table and extends at least 0.3 m (1 ft.) beyond the leading edge of the spread. The underlay lets you move the spread without pulling or disturbing the material. When vacuum is applied, the underlay keeps the material clean and in place. It also provides extra support for stretchy and lightweight material.
2. Using the method appropriate for your site, spread the material on top of the perforated paper. Normally the straight edge is on the operator’s side of the cutting table.
CAUTION: Do not exceed your GERBERcutter’s maximum compressed material ply height (see the System Description in documentation for your cutter).
Exceeding the maximum material ply height will lower cut quality, shorten knife life, and may damage your GERBERcutter.
3. If you use full–size plots to identify individual pieces after they are cut, put the correct one on top of the spread.
Basic Cutting
The following sections explain how to use C-200MT features to perform basic cutting procedures.

Note: Read the safety precautions at the beginning of this manual before performing any operation at the cutter.
Basic Cutting 39 Turning on the Cutter
Depending on your GERBERcutter, circuit breaker(s) and/or a switch located outside of the vacuum and electric enclosure(s) allow you to turn power ON or OFF for the FEP (or PC), vacuum system, C-200 cutter controller, servo motors, and conveyor. Enclosure(s) may be located at the side or at the end of the cutter or on a separate table along side of the cutter.
To turn on the main power circuit breaker for your cutter, see the Safety Procedures chapter in this manual.
Enabling Servo Power
Pressing the Servo Power Enable switch turns on power to the servo motors. These motors move the cutter head and beam during cut processing.
To enable servo power
1. Make sure that cutter power is turned on and the C-200MT program is running.
2. When prompted, press the Servo Power Enable switch. Depending on your GERBERcutter, this switch may be located at the operator console or at the beam control panel.
The servo motors are turned on and gauges display across the top of the Main Cutter Control screen.
Initializing the Cutter
Use the Initialize feature to identify the zero position for the table in X and Y. This is also called the home position and is written as (0,0). Limit switches tell the C-200MT when the cutter head reaches the (0, 0) position.
For information about basic cutter concepts, see that chapter in this manual.
Note: You must initialize the cutter before processing markers. Otherwise, an error message displays.
To initialize the cutter
1. Make sure that the cutter power is turned on, the C-200MT program is running, and the servo power is enabled.
2. Do one of the following:
− Press the Initialize switch on the beam control panel.
− Press the Initialize key on the keyboard.
− From the Cutter menu, selectInitialize. − Click the Initialize button on the tool bar.
The cutter head and beam moves to the (0,0) position on the table and the origin is reported in the System Messages box.
Note: If the cutter is set up for the Right Side Option, the cutter head and beam moves to the right side of the table.
Positioning the First Bite
After the cutter is initialized, use the jog switch at the take-on end of the cutter to advance the spread (material) into cutting position on the table. This will be the first bite. Then cover the spread with plastic film. For specific information on spreading a marker and positioning the first bite, see the first page in this chapter.

Field Description
Cutter Type The cutter type does not automatically change the default values of the table.
STATIC is a type of GERBERcutter that has a fixed cutting surface equal to the table length.
CONVEYOR TABLE is a type of GERBERcutter that has a continuous belt for the cutting surface. As the spread is fed on from one side, the cut pieces come off the other.
TRAVELLING CONVEYOR is a GERBERcutter that moves from one spreading table to the next on floor rails.
Table Length Usable table length. Table Width Usable table width.
X Scale Determines the scale of the cut data in Y direction on the table. Y Scale Determines the scale of the cut data in X direction on the table. Perimeter
Tool
Choices are:
KNIFE to cut the marker
PEN to plot the marker if the cutter is equipped with a pen BLANK the perimeter will not be cut or plotted
First Bundle Code
The default bundle code is A and can be edited with numeric or alphanumeric values.
Edge Tolerance
Used for tubular goods. If the piece perimeter is placed within the given tolerance, the cutter will dry haul for the fold. The pattern dimensions are increased to the defined value.
Maximum Move
This safety feature controls the cutting head on long straight lines. Data points are added during cut process if a straight segment is over the
indicated value.
Fold Overcut Used for tubular goods. The cutter will cut the defined amount past the edge of the marker on folded pieces. This is to make sure the piece is fully cut. The folded pieces must have the piece option F assigned. Cut Small
Slow
Used to ensure good quality on small pieces by cutting them at the indicated percent of full speed (increments of 5 with a minimum of 60%). This prevents pushing; refer to the Applications manual for your cutter.
Field Description
Bite Clip Amount
The length of a cut made in the selvage of the goods. Used to reorigin the cutter head at the beginning of a bite for a conveyor. See Bite
Parameters.
Park in Bite When cutting lofty goods, the cutting head needs to be moved to the edge of the table when the GERBERcutter advances. Otherwise, when the vacuum releases, the goods are no longer condensed and could be damaged. This is calculated based on 0.00 as the origin. To move the head to the far side of the fabric, enter the width plus an additional amount to ensure the head moves off entirely.
See Bite Parameters.
Bite Length Indicates a specific bite length for the available cutting surface. See Bite Parameters.
Bi-L/R Cut NO means the option will not be activated
YES indicates lefts will be cut in opposite direction from rights. Bi-L/R Mirr
Cut
NO indicates mirrored pieces will be cut in clockwise direction
YES indicates one half of mirrored piece will be cut in opposite direction from the other half on a common perimeter point of the mirror line. The cutter will dry haul back to the center back hem and resume cutting in the
