Job Settings

A set of appropriate job settings is one of the most important technology for getting good laser results.

Layers

There are twenty layers available in EagleWorks, which are represented by different colors and independent of each other. A set of processing parameters, associated with a layer, will be applied automatically to the shapes or images which are assigned to the layer.

Layers

In general, different kinds of operations on different materials with different thicknesses and surfaces require different sets of processing parameters. In practice, we recommend to create a one-to-one mapping between the most commonly used operations and the first few layers, e.g. 3mm acrylic cutting to layer Layer 1 , 5mm plywood cutting to layer Layer 2 , and temporarily assign other operations to the last few layers when necessary, e.g. 2mm cardboard cutting to layer Layer 20 . When setting processing parameters, all you need to do is just assigning the shapes to the layers.

To assign a shape to a layer, select the shape and then click on the color of the layer.

Assign A Shape to A Layer

Sometimes, if you want to process just a part of your design, select those shapes which you want to ignore and assign them to the layer set to be ignored.

Ignore A Layer

You can also check the option Output select graphics in Process Control Bar to do the same thing, refer to Laser Panel for more details.

There is a list of all the layers in your design in the tab Work of System Work Plat.

Layer List

You can get some basic information in the view, i.e. the processing mode of a layer, whether the shapes of a layer will be processed, whether the shapes of a layer will be displayed. Double click on the option Output or Hide of a layer will switch its corresponding state.

By selecting a layer, you can review the speed and power settings of the layer. On a dual-laser machine, click Laser1 to show the power of the laser 1, click Laser2 to show the power of the laser 2. You can do a quick change by modifying the values directly here.

Shared Layer Parameters

To set the processing parameters of a layer, there must be at least one shape in the draw area.

Double click on the layer in the layer list in the tab Work of System Work Plat, the dialog Layer Parameter pops up.

Layer Parameters

NOTE

You can switch to another layer by clicking the color of the layer in the list on the left side without closing the dialog and opening it from the layer list again.

There are a set of shared parameters for both cutting and engraving.

Parameter Description
Layer The color representing the layer.
Is Output Whether the shapes in the layer will be processed.
Speed The speed for cutting or engraving.
Repeat num How many times the laser will repeat the shapes and images in the layer.
Processing Mode Set the processing mode of the layer.
If Blowing Whether the exhaust will be turned on.
Min Power 1-6 The minimum power for cutting or engraving.
Max Power 1-6 The maximum power for cutting or engraving.
Auto synchronize when Modify laser para Change the power of all lasers at the same time.

On a dual-laser machine, you need to enable the power settings for the both lasers.

Sometimes, especially when cutting thin sheets in a high speed, the material will catch a lot more heat at the start, end and sharp corners because of the low feeding speed at these positions and results in over burnt edges. In these cases, you should set a low minimum power, e.g. just above the firing threshold, and the software will generate a linear power curve, then the machine will adjust the power level based on the real-time feeding speed.

Cutting Parameters

Set Processing Mode to Cut will bring up all the cutting parameters.

Cutting Parameters
Parameter Description
Seal The length of over-cuts which may result in more smooth edges at the start and end positions.
Open Delay The time period after turning on the laser and before the laser head starting feeding, helping get better edges at the start positions.
Close Delay The time period after the laser head stopping feeding and before turning off the laser, helping get better edges at the end positions.
Laser through mode Switch the option Open Delay and Close Delay on or off.
Through power 1-6 The power setting for Open Delay and Close Delay.

Engraving Parameters

Set Processing Mode to Scan will bring up all the engraving parameters.

Engraving Parameters
Parameter Description
Negative Engrave This will invert the image during engraving, effective for BMP layers only.
Optimized Scan Let the software calculate and set the spacing between scanlines, effective for BMP layers only.
Output direct Let the machine adjust the power level based on the gray scales of the image, effective for BMP layers only.
Independent output The laser will engrave each shape or image separately.
Ramp Effect The laser will slope the sides of an engraving by varying the power level, typically used for rubber stamps, especially if a design has thin regions that need extra support.
Ramp Length Control how far from the design the slope will extend.
Overstriking
Scan Mode Control how the laser carries out engraving.
Interval Control the spacing between scanlines.

When Scan Mode is set to X_swing, the laser will sweep the material in a side-to-side pattern, engraving in one direction and again for the return direction. When set to X_unilateralism, the laser will engrave in only one direction and travel back to the start of the next line.

We recommend to change the unit of the option Interval to DPI, a more intuitive way of representing the pixel density of the output, and then set the resolution value there, such as 500.

Layer Parameter Library

The layer parameter library provides a way to store and organize presets for different operations on different materials, and a way to quickly apply them.

To add a preset to the library, click the button Parameter library after finishing setting up parameters to bring up the dialog Parameter library.

Parameter Library

Click Save as, fill in a name and a note, click Ok. We recommend to name a preset in the format “[Laser Power]-[Material Thickness]-[Material Name]-[Processing Mode]”, e.g. “130W-3mm-Acrylic-Cut”

Add A Preset

And then you will see the new preset in the list. To load a preset into the current layer, select it and click the button Load.
