7 Add bridge： Adding bridge on the curve element is in order to supply supporting point. So the curve is split into many

segments. Laser will be off during the bridge path.



40

Picture 2-27 Adding bridge

You can set the bridge is all break or semi-break. If you select the all-break mode, laser will be off during the bridge path. If you select half-break mode , laser will be on with half power during the bridge path. The bridge width can be set too. The unit is mm. There are 3 ways to generate the bridge. One is generating the bridge with interval length. Another is generating the bridge with interval bridge quality. The other is generating bridge manually. 1) Generate with interval length：When lasercuttist has been in the adding bridge status, you can generate bridges on the curve with the interval length. 2) Generate by number：When lasercuttist has been in the adding bridge status, you can generate bridge on the curve by number. 3) Generating bridge manually：

When lasercuttist has been in the adding bridge status, you can click the left key to generate a bridge on the curve. 8 Re_Locate：

Relocate function is just for relocate the offset and rotation parameters of metal material. With these parameters, lasercuttist can change the curve element coordination to achieve a correct result.

For example, the metal material has been cut for a quality of curve elements. But the metal material location has been changed. So if you want to continue to cut the left curve element, you should use the relocating function. 9 Statistics：



41

Picture2-27 Statistics function

The statistic information is including of cut path length, jump path length for all the elements in the display window.

It can display the number of the selected curve elements and the cut path length, cut area, cut ratio of selected elements.

Cut path length is the length of the path that needs to be laser on. 10 Data check： Data check is include of close, intersect, self-intersect, overlapping. Lasercuttist can handle these incorrectly data automatically.

Picture 2-28 Data check

1) Closure check： To check the curve is closed or not. If the distance is less than the close error limit, lasercuttist will close the

curve automatically.



42

2) Self-intersect check： If a closed curve is self-intersect, lasercuttist will separate the curve.

3) Intersect check： To check the curves is intersect or not. If there are intersections, lasercuttist will automatically merge the intersection line.

4) Data overlap check： To check the curve is overlap or not. If there are overlapping, lasercuttist will delete the overlapping lines. Notice: this operation will made a closed curve to be a un-closed curve.

10 Cut simulation： There is a simulation if the cutting process. Shown as picture 2-27.

If you want to cut from the start curve, you can press zero buttons to set the curve number to be zero and press start button.

Chapter 3 Fast operation User should follow the steps when user executes a machine test. But before test, user should cut off the connection to the servo amplifier. Because the machine motion and the laser can cause harm if incorrectly operated. The test steps are: （1） Test the limit switch, home switch. Make sure them can work correctly. （2） Test the tracing head moving. （3） test the air valve control. （4） test laser （5） test motor motion and the limit function （6） test HOME motion



49

3.1 Test Preparation

When start a cut task, the integrants of the laser cutting system should work normally. So the machine should be checked in detail. This usually happened in the first machine test after the machine has been assembled.

The follow check you should do： Limit switch work normally， limit switch should protect the X,Y axis avoiding of

collision. Home switch work normally, X, Y axis can go home correctly. Tracing head can be controlled normally Air valve can be controlled normally Laser can be controlled normally

3.1.1 IO input and out put test

Before motion, the IO should be test. The test dialog can be opened if you click TEST—SIGNAL CHECK. As is shown in picture 3-1.

The dedicated IO displays the status of limit and home switch. Red represents electrical low level. Green represents electrical high level. User can manually open or close these switch and check the status. If the status is changed with the switch’s on or off, that means the switch is work well.

For example, if the switch is Normal Open, one terminal is connect to OGND, another connect to the limit in. So when you press down the switch, Green will be displayed. When you release the switch, red will displayed. The reverse is to Normal Close.



50

Picture 3-1 Machine Test The general purpose output (out27) is assigned to laser on/off control. Out26 is assigned to air valve. Out25

is assigned to tracing head rising control. Out24 is assigned to tracing head tracing.

When OUT27 is test, please take care of laser emission.

3.1.2 Axis motion test

When the general purpose IO has been test, then the axis motion test can be executed. Before the test, user should connect the servo amplifier to the controller properly. Then click “TEST—machine test”. As is shown in picture 3-2.



51

Picture 3-2 Machine test In the dialog, we can move the axis for a length that described in pulses. Acceleration and velocity should be set. If we want X axis to move, the axis X should be selected. Moving to the positive direction or moving to the negative direction can be set also. Click” send”, then the selected axis will move for a length. If you want to stop the motion, click “stop”.

Because we may not know the coefficient (pulse/mm) , so we can not set the velocity and position too large. If we can calculate the coefficient (pulse/mm), please set the coefficient to lasercuttist correctly.

In the machine test , we just want to test the limit and home function can do well or not. Motor control is normal or not. We still can test the coefficient (pulse/mm) by the function. For example, We set 10000 pulse motion. Before start motion, we mark a point on the work plane. Then start a motion for a movement of the 10000 pulse. Then mark another point. We can measure the distance of the two mark point. Using the 10000 pulses divided with the distance can generate the coefficient (pulse/mm). The coefficient (pulse/mm) calculation can be executed in the “Parameter—machine parameter”. During test the limit function, a low velocity motion should be executed, during the motion, presses down the limit switch that in the same direction, the motion should be stop. You must be sure that the limit function is normally firstly. Based on this, other motion test can be executed.

Notice：Positive and negative is just means the CCW or CW of the motor. The Positive

and negative do not means the X,Y axis direction.

3.2 Start a cutting task

Start a cutting task should follow the steps: （1） Build up coordinate （2） Draw or import a work data file （3） Pre-handle data file （4） Machine, cut parameter configure.



52

（5） Process parameter configure （6） Run and the running information

3.2.1 Build up coordinate

In the laser cutting system, the coordinate is very important. According to laser cut machine, there are usually 2 coordinates. One is machine coordinate. Machine coordinate is generated by the home switch that install in the machine. Once the position of the home switch is fixed, the machine coordinate is fixed. As is shown in picture 3-3.

Picture3-3 Machine coordinates After home switch is installed，The parameter of the home switch should be set properly in order to run a motion

correctly. Picture 3-4 shows the parameters about the home。



53

Picture3-4 Machine parameter Direction polarity defines the running direction of motor X or Y. Home polarity and limit polarity should be set correctly. If the home switch is normal open, the home polarity should be set negative. If the home switch is normal close, the home polarity should be set positive. The same is to limit switches. The parameters marked with red arc lines should be set properly. Especially for the “Origin pos”, it should be set properly. The four points is according to the four corner of the machine. Once the home switch is installed, the origin position is the same position with the home switch.

Notice：The origin position must be set correctly according to the home switch position.

The coordinate is including of absolute coordinate, current position. If you have execute a going home operation, the coordinate is absolute coordinate.

When you import a data file, lasercuttist always display the file in the center of the valid cutting area. But user can move, rotate the curves.

When start a cutting, how the laser head moves and cut the metal material? So there are 3 conception to explain. As shown in picture 3-5.



54

Picture 3-5 Coordinate definition (1) Absolute coordinate：

When you select the absolute coordinate, lasercuttist will consider the machine home point as the curve referenced point. That means the valid cut area is just the same to the machine platform. The curve locates in the area is the same location in the machine platform. As shown in picture 3-6.

For example, cutting a rectangle, when absolute coordinate is selected, the laser head will jump from the current point to the start point of the cut rectangle. Then , starts a cutting operation. When finish cutting, the laser head will stay the end point. If you select the “run to stop point”, the laser head will move to the stop point when finished the cutting.

Picture3-6 Laser head movement

(2) Current point coordinate： When “current point coordinate” is selected, lasercuttist will consider the current point as the

referenced point of the curves. The curve has 9 kinds of referenced points. As is shown in picture 3-8. So the referenced points of curve have 9 kinds of relationship with the laser head. As is shown in picture 3-7. Picture just only list 4 kinds.

During cutting, blue dotted line means jumping, black line means cutting. The red array means laser head. In the 9 kings work mode, the laser head location is not changed. Lasercuttist will change the location of the curve.

Every data file has a default referenced point that displayed with green rectangle. The referenced point can be changed by user. The change operation is in the “Parameter—system Para”.



55

Picture 3-7 Current point coordinate movement



56

Picture3-8 Reference point (3) Orientation point coordinates.

Orientation point coordinates supply a more flexible work mode. If user imports a data file and want to cut the curve on the special Orientation point of the machine platform, the orientation point coordinates function should be selected. Under the orientation point coordinates, referenced point of the data file has 9 kinds relationship with the orientation point. As shown in picture3-9. This function is like the “current point coordinate” mode. The only deference is current point and the orientation point. The orientation point is referred by manually move the X,Y axis.

The orientation point is not changed when you have referred them. The curve referenced point can be changed according to the 9 kind’s referenced mode. The orientation point information is saved in the *.rlc file. If user open the *.rlc file , the orientation point information will be uploaded and be configured. (4) Set stop point

When finishing cutting a data file, the laser head may have 3 kinds return mode. One is return to machine home point. Another is return to stop point. The other is stay there. As is shown in picture3-10.



57

Picture 3-10 Return to point after cutting

Click can set the stop point to anywhere on the cut area. If user wishes that the laser head return to the stop point when finish cutting, the option “return to stop point” should be selected. Shown as picture 3-11.

Picture 3-11 stop point select

To set the stop point in the cut area, you should click , and then a dialog will appeared as shown in picture 3-12.



58

Picture 3-12 stop point set The X,Y position that displayed in the dialog is the laser head current location. You can set the laser head current position to be the stop point. You still can set any position on the cut area to be the stop point. Click” mouse to set” and click any position on the cut area with the left key. The current point X, Y position will displayed on the dialog. Lasercuttist will consider the point as the stop point. The stop point is displayed with the red target.

3.2.2 File import

Lasercuttist support the *.plt；*.ai；*.dxf；NC code. When you import a PLT or a DXF file, you should set the data unit. As is shown in picture 3-13.

Picture3-13File import option The default PLT precision is 1016. The default unit of DXF is mm. you can change to cm. Curve information and attribute

Importing a data file, user can get the file information and attribute. Polygon lines can be seen if you click “view-display node”. As is shown in picture 3-14.



59

Picture3-14 Polygon lines display User click “view—show path”, the cut path and the sequence of the curve element will be displayed. The cut sequence is marked with number. The jump path is displayed with dotted line. The arrow displays the motion direction. As is shown in picture 3-15.

Picture3-15 motion path display

Statistical information Click” modify--statistic”, the statistical information will be displayed. The information is include of the



60

whole cut length, the whole jump length. If you have select one or some curve elements, the information of the curve elements will be displayed. The information is including of the number of selected curves, the whole work length, all the curves area, the coefficient of utilization. Shown as picture 3-16

Picture3-16 Statistical Information The area and the coefficient of utilization is relation with the attribute of the curves. So we must know the sense of the inner mold and outer mold.

Seeing picture 3-17, The left curve is the imported data file. The right is the product after laser cutting. So in order to get the correct result, we must set the inner mold and the outer mold of the curves correctly. If we set a curve is inner mold, it means the outer part of the outline is useful. The inner part is rubbish. If we set a curve to be an outer mold, the inner part of the curve outline is useful for us. The outer part of the curve outline is no useful. So there is at least one outer mold in the curve elements.

See picture 3-17. We want to cut a butterfly. So before we start a cutting, we should set curve element 1 to 16 to be inner mold. Curve element 17 should be set to be outer mold.

Picture 3-17 Inner mold and outer mold Imported data check

As to the imported data file, the file has some discrete error. We usually can not tolerate the error when we cutting a product with high precision. So some check and revision must be done. Lasercuttist give some tools to check and revise the data.



61

Click” modify—data check”, the dialog will appeared. As is shown in picture 3-18

Picture3-18 Data check and revise Select some or all the curve elements, then execute a data check. The check result will display in the dialog. When the distance between the polygon line and another polygon line is less than the close error limit,

lasercuttist will close the two polygon lines automatically. When some polygon lines are self- intersection, lasercuttist will handle the self-cross and cross polygon lines

if you have selected the deal self-cross and deal cross. When the vertical distance of two polygon lines is less than the overlap error limit, Laser cuttist will delete

the two polygon lines automatically if deal overlap is selected.

Notice：When the curves has been selected, the data check can be executed. 。

3.2.3 Parameter set

The parameters of lasercuttist are include of machine parameter and cut parameter.

1 Machine Parameters

Click the “Parameter ---machine parameter”, the dialog will be opened. As is shown in picture 3-18.



62

Picture3-18 Machine Parameters Motion direction polarity When you open the “Test---machine Test”, you can run a motion test. If you send positive pulses to the motor, the direction of the axis moving is opposite to the machine positive direction that has been decided by the home switch. You should change the polarity of the direction polarity. The default is positive. Home switch Polarity

Home switch is for the machine going home. If the motion axis has met the home switch, the home switch is triggered. There are two statuses when the home switch triggered. One is low level and the other is high level.

If the home polarity is set to be negative, that means lasercuttist will consider the valid level is low. If the home polarity is set to be positive, that means lasercuttist will consider the valid level is high.

For example, the home switch is normal open. One terminal of the home switch is connected to OGND and the other terminal is connect to the control board home input. The home polarity must be set negative. That means the valid level is low level. If the home switch is normal close, The home polarity must be set positive. That means the valid level is high level. Limit switch polarity

Limit switch polarity configuration is similar to home switch polarity configuration.



63

Control mode The motor control output is pulse + dir. Pulse equivalency Pulse equivalency is the conversion relation of the rotate pulse and the axis line movement.

Pulse equivalency is very important and should be set correctly. You can follow the steps to set up the pulse equivalency. (1) Firstly you should calculate the pulse equivalency according to the pitch of screw

and pulses when motor turning one circle. (2) Then write the theoretical pulse equivalency to machine parameters.

The theoretical pulse equivalency must have some error with the actual pulse equivalency. So the value must be revised.

(3) Running X axis for a 200mm movement, marked on the start point and the end point. Measure the distance between the start point and the end point. Then write the 200mm and the actual distance to the dialog. As is shown in picture 3-19.

(4) Click ok, the pulse equivalency will be calculated automatically. The same steps to the Y axis.

Picture 3-19 pulse equivalency calculate Cut Range

Cut range should be set for the soft limit. Another purpose is to make the cut window displayed in the lasercuttist similar with the machine cut platform. Maximum velocity



64

The maximum velocity that the machine allowed. Start velocity

The start frequency of the motors. Maximum accelerator

The maximum accelerator that the machine allowed. Emergency stop accelerator

When the axis made the limit or the alarm valid, system will emergent stop with this accelerator. Manual accelerator If you use the manual operation panel, axis moves with the accelerator

If all the parameters is configured, you can click the “write” to download the parameters to the memory of controller for a permanent saving. You can still upload the parameters form the controller’s memory. You can still upload the parameters from a file named *.rdset.

2 Cut parameters

Cut parameters are include of motion parameters and delay parameters. As is shown in picture 3-20.

Picture3-20 Cut parameter set up （1）Cut parameter Jump velocity、Jump accelerator

The velocity and accelerator of the jump motion. There is no laser emit during the jump movement. So the velocity is usually to be set much larger than the cut velocity and accelerator. Look ahead coefficient. The look ahead coefficient will affect the turning corner velocity. If there is a serious shake during turning corner, the ahead coefficient should be decreased. Cut accelerator



65

The accelerator used in the cutting. The cut velocity is located in the layer parameters. Motion delay: The delay that is inserted after the jump motion . Frame blank When the frame black is set, The actually going scale will enlarge the curve’s frame. Going home velocity Lasercuttist goes home with the velocity. The accelerator is decided by the jump accelerator. XY home offset

The offset between the home switch position and the real machine home. （2）Delay parameter Penetrate delay

Laser head jumps to the start point of a curve. And then execute a penetrate operation with laser on. In order to penetrate a hole on the metal material, the laser will be on for a time. The time is the penetrate delay.

Tracing delay The time that the laser head spend when running down to the metal material platform. The time can not be set too small. If the time is too small, the laser head can not reach to the metal material platform and start tracing status. If the time is too long, the efficiency will be very low. User can click the button on the lasercuttist to control the tracing head rising or running down. The tracing delay can be measured through this way. As is shown in picture 3-21

Picture 3-21 Tracing control

Gas open delay The time from the open the air valve to the laser on. The delay is just for gaining a stable pressure. It is usually to be set less than 100ms.

Gas close delay When finishing a cutting task, the laser will be off immediately. But we usually want the air to blow for a time after laser off. The time is the gas close delay. Rise delay Rise time means the time that the tracing laser head rises from the metal material platform



66

to the referenced height.

3.2.4 Cutting simulation

There is a cutting simulation environment for user to observe the process of the cutting. Through the window, user can see the path and time of a task. As is shown in picture 3-21.

Picture 3-21 Cutting simulation

3.2.5 Cut processing technique

The cutting process is include of bridge, introducing pin-in-out line, outline compensation, path optimization, look back, parallel lines, re-location, inner and outer mold.。。

1 Add bridge Bridge is also called supporting point. In metal cutting application, avoid of the curve element drop off

from the metal material after cutting, we usually add some support point in the curve. There are 2 type of bridges： Whole bridge

In this mode, the bridge is connecting to the metal material. There is no laser happen on the bridge. Half bridge

In this mode, the bridge is half connecting to the metal material. There is laser happen on the bridge with half laser power.

There are 3 ways to add the bridges: Add bridges with interval

The bridge width and the interval of the bridges should be set. If you have set the parameters



67

correctly, click “apply”, the bridges will be added on the curve automatically. Add bridges with the number of the bridges.

If you select adding bridges with the bridges number, the number of bridges to be added should be set. Then click “apply”, the bridges will be added automatically.

Manually add bridges We can add the bridges manually. Select the “manual’ option and set the with of the bridge, you can add the bridge anywhere on the curve. Shown as picture 3-22.

Picture3-22 Adding bridge 2Introducing pin-in-out line

During laser cutting, the penetrate hole are usually located on the throwing away part of the metal material. So the introducing pin-in-out line is always located on the throwing away part of the metal material.

The introducing pin-in-out line are the lines that connect the penetrate hole and start point of the curve outline. 2 type of introducing line：

Line The length and the intersection angle can be set. The result of the introducing line is shown as picture 3-23.



68

Picture 3-23 Introducing line arc

Picture 3-24 Introducing arc of inner mold The length of the arc can be set. The attribute of the above curves is inner mold (the internal area is garbage). The introducing lines is happened in the garbage area. If user forces to modify the curve to be outer mold, then lasercuttist will force to change the introducing lines. As is shown in picture 3-25.

Picture 3-25 Introducing arc, line of a outer mold

Two ways to adding the introducing lines： Automatic

Automatically adding introducing line is in the” handle—add introducing line”. As is shown in picture 3-25.

Picture3-25 Adding introducing line automatically If you want to add a introducing line to the curve, the introducing line is added on the start point of the curve. If the curve is set to be inner mold, the finally result is shown in picture 3-26.

Picture3-26 Add the introducing line of inner mold After adding the introducing lines, lasercuttist is in the introducing line edit status. A cross on the cursor is displayed. Now you can modify the introducing line. There is a small rectangle on the introducing pin-in line. There is a small green rectangle on the introducing pin-out line. User can press down the left key and drag the blue or green rectangle to modify the introducing pin-in-out line.

If you want escape the introducing line edit status, please press the right key of the mouse. Manual

Click “handle—add introducing line”, The dialog appears as shown in picture 3-27. In the manual mode, the introducing pin-in line and the introducing pin-out line can be added independent.

Picture3-27 Add introducing line manually

Notice： If the attribute of the curve is inner mold, the introducing line can be only added

inside of the outline of the curve. Introducing pin-in-out line edit：

Whatever introducing pin-in line or introducing pin-out line, they can be edited again. When user has added the introducing lines, the introducing lines are in the edit status. A cross cursor is displayed with the mouse cursor. So you can move the cursor to the green or blue rectangle at the terminal of the introducing lines. Press down the left key of the mouse and drag the introducing line to wherever you want to drag. Press the right key of the mouse can escape from the introducing line edit status.

You can press the tool to edit the introducing status. Then the cross cursor will appears and the introducing lines are in the edit status.

Notice：When modifying introducing lines, lasercuttsit will judge the position that the

introducing line is added automatically according to the inner and the outer mold. If the position is illegal, the introducing line will be not allowed to be added.

Delete the introducing pin-in-out lines： Before deleting the introducing pin-in-out lines, You must selected the curves. Click



71

“handle—delete introducing line”. The introducing lines will be deleted. 3 Sequence manually:

In order to improving the efficiency of the cut, the sequence of the curve elements should be arranged again. Lasercuttist supply the tool to arrange the curve elements. When a data file is imported, the path of cutting and the sequence of the curve elements can be

displayed in the window if you have pressed the .As is shown in picture 3-28.

Picture3-28 Cutting path and sequence The number displayed on the curve is the sequence of the curve element. Blue dotted line means the jump path. The direction of the arrow means the direction that laser head moves.

When user want to modify the sequence of the curve elements, please click “handle—sequence manually”. The dialog will be displayed. As is shown in picture 3-29.

Picture 3-29 Sequence manually User can select the curve and throw into the right field. The first is No1 and so on. Not only the sequence of the curve element can be modified, but also the start point of a single



72

curve element can be modified. Click the Green button and double click the left key of

the mouse on the outline of the curve. Then the start point is set. As is shown in the picture 3-30.

Notice: The start point can only be set on the polygon point.

Picture3-30 Modify the start point and sequence manually

4 Paths 0ptimization Click “handle—path optimization”, the dialog is opened. As is shown in picture 3-31.

Picture3-31 Cutting path optimization

Path optimization is including of two options. One is optimizing all the curves of the data file. The other is optimizing the curves by layer.



73

Notice：Cut optimization is always following the rule of shortest path.

A very important requirement in metal cutting is cutting curves from the inside to the outside. Select the “inside to outside” can do this. Then lasercuttist will cut all the curves from inside to outside. As is shown in picture 3-32.

Picture 3-33 select“inside to outside”and“auto determine start point and direction” If the “start point optimize” has been selected, the “auto determine start point and direction” will be disabled. Start point optimize option will change the start point to the special position on the curve in order to gain a good processing effect. As is shown in picture 3-34.



74

Picture3-34 Start point optimization When you want the cut sequence from left to right or from top to bottom, the “block handle” will be set. The size of the block and the direction can be set.

5 Outline compensation Click “Edit--Outline compensation”, the dialog is opened. As is shown in picture 3-35. 。

Picture3-35 Outline compensation If “zoom in” is selected, the outline will be zoom out from the original outline. If “zoom out” is selected, the outline will be zoom in from the original outline. If “auto compensation” is selected, lasercuttist will zoom in or zoom out automatically according the attribute of the curve.

6 Parallel lines If a curve is just a polygon line and you want to cut a wide gap, the parallel line function can be used. The offset can be set. As is shown in picture 3-35.



75

Picture 3-35 Parallel line For example, a polygon line is drew in the window. If you execute the parallel line function, two lines will be added to the original polygon line. As is shown in picture 3-26. The black line in the picture is the original line and the red lines are the parallel lines added. If you do not select “delete original line”, then there 3 parallel lines. Now if you start a cutting, 3 lines will be cut. If you select “delete original line”, the original line will be deleted. There are two lines totally.

Picture3-36 Parallel lines 7 Re-locate

When user want to cut some curves on the metal material that has some special mark point, you must locate the metal material again according to the mark point. Only this is done, the curves can have a certain relation with the mark point.

When you execute a re-location, please follow the hint displayed in the information area of lasercuttist.

3.3 Information display

The information of cutting is displayed on the right control panel and the status area on the bottom. Just shown in picture 3-38.

Picture 3-38 information hint area

The position of the cursor, machine status, coordinate mode, attribute of curve can be displayed. The count of the data file has been cut is displayed in the area too. Control panel is on the right of the window. The position of machine coordinate and the position of the work
