Cut File Steps

1. Import File

Import File Compatibilities:

  • .dxf - 2D file type that most engineering and design software will export.

    • The .dxf library supports arcs, circles, ellipses, lines, polylines, and splines.

    • All text must be converted to vector paths.

    • .dxf files do not include units – Wam tries to infer the correct units, but if it cannot, the part will default to inches.

  • .svg - 2D Vector file that most design software will export.

    • Ensure that the output format for files is set to Plain SVG.

    • All shapes and objects should be simplified as paths.

    • Make sure the document units are set to physical units and not pixels.

    • Pictures and bitmaps will be ignored.

 

Import File Checklist

Convert all desired cut edges from objects to paths

□ Convert all text to vector paths.

□ Check for gaps.

- If path fragments are 0.0010 inches apart or less, Wam will merge the fragments into a single path.

- If a path start and path end are less than 0.0020 inches apart, Wam will merge the points and treat the path as closed.

- Unconnected line segments less than 0.0001 inch long are deleted.

□ Join and trim paths if necessary.

□ Check for overlapping segments.

- Overlapping Cut Groups may not be visible but may cause issues.

□ Check for dangling or default Cut Groups.


It is possible to import multiple Designs, or the same Design multiple times in one Cut File. Manage these Designs by using the +, -, and X Icons. 


Cut Groups
Wam takes every Design and divides it into Cut Groups. A Cut Group includes all elements contained within a closed curve. The easiest way to understand this is to imagine a Design consisting of two concentric circles. These circles will be imported as one Cut Group, where the two circles are locked in reference to one another.


Split
It is also possible to upload multiple independent curves outside of a closed curve from a single .dxf or .svg file. When these curves import they will maintain their positions and groupings, and they can be moved about the Virtual Cut Bed as a group. If you would like to manipulate each curve independently, select the Split option in the File menu. This will break any curves not contained within a closed curve into independent Cut Groups that can be manipulated independently.

 

2. Scale and Rotate

Wam allows you to manipulate individual Cut Groups within the Virtual Cut Bed:

Rotation – sometimes, if you want to nest as many Cut Groups as possible into a single Cut File it can be helpful to rotate a Cut Group.

Adjust Scale – for many applications, you will require your Cuts to be sized precisely. Some programs will Scale your Design in unexpected ways when exporting, so you will need to re-scale your Design back to the intended size.

There are two methods to re-scale your imported Cut Groups:

Scale - specify a scaling factor into the field to Scale the selected Cut Group(s) to size
Width/Height - specify the intended major extent of the imported Cut Group (width or height) to Scale the entire Cut Group proportionally.

 

3. Choose Material Settings

WAZER needs to know the Cut Rate, or how fast it can cut, for your Material. Rather than relying on the user to calculate and enter this directly for every Cut, we have created a Material Library that holds all this information. You can simply specify your Material and thickness from the available selections, and Wam will set the correct Cut Rate.

When you log into Wam, the software will automatically load the most recent Material Library for you to select from. We will constantly be expanding this Material Library.

There may be some instances where a Material is not in the Material Library yet. If this is the case, you will have to manually Add Material, which is done easily through the Add Material menu (more on this later).

The organization of Materials is done by Material Type (i.e. metal, plastic, etc.), and then by specific Material (i.e. aluminum, stainless steel, etc.), and finally Material Thickness (i.e. 1.0mm, 1/16”, etc.).

Default Material entries are indicated by a "W" Icon, while your personal Material entries are indicated by a "USER" Icon.

WAZER currently only supports the selection of one Material per Cut.

 

4. Configure Cut Path

When a Design is imported into Wam it is simply a set of curves. These curves are shown in white.

To cut your parts properly, WAZER needs to know which side of the curve to Cut. As a result, the Cut Path needs to be specified as either Outside or Inside.

Once you have made a selection, a green Cut Path appears around or within the white part geometry. This green line indicates the actual path of the WAZER. You can use it to check if your Design will be Cut correctly.

It should be noted that there may be instances where you want to cut directly on the Cut Path. You can specify this using the Centerline option. In this case, you will notice that the green Cut Path completely covers the white geometry.

To aid in quick setup and accurate Outside and Inside Cut Paths, the software automatically defaults the offset value based on the Jet
size (you can change the default in the Wam options).

There may be instances where you desire an additional offset to make your Part slightly smaller or slightly larger. To do this quickly, change the preloaded offset by the amount you would like to oversize or undersize your Cut.

 

5. Set Up Tabs and Leads

A Tab is small connection point between your Part and the Material from which it is being Cut, designed to keep your Part in place for the duration of the Cut. Tabs help to increase overall Accuracy and prevent Pop-Ups, which can cause the WAZER to jam and ruin your Cut.

Wam automatically defaults to incorporating Tabs in default locations of each Cut Path. The location and size are designated on the Cut Group with a yellow indicator.

The default settings are that every Cut Path receives a single Tab of a size based on the Material. This will likely be sufficient for most Cuts and will seldom need to be changed. However, you should always review the default locations, in case they will cause problems with your Design.

If you need to make changes, select Manual Tab Placement and move the problem Tabs
by left clicking and dragging them. You can also add and remove Tabs by left clicking. Additionally, there may be use cases where you cannot afford to place any Tabs, as a result you may want to select No Tabs. This is highly discouraged, however, because it greatly increases the risk of poor or failed Cuts.

A Lead refers to the distance that WAZER will be cutting away from the Cut Path. This is done to make sure that the oversized Pierce at the start of a Cut doesn’t remove any excess material on your Part. The Lead’s location and size are designated on the Virtual Cut Bed with a blue indicator.

[NOTICE] When considering using No Tabs on a Cut, make sure you can afford a failure. There is a high likelihood that these parts will come loose, resulting in them either falling into the Tank or jamming the Nozzle.

 

6. Set Cut Quality and Finalize

The last required selection in Wam is the Cut Quality. Cut Rate and Cut Quality have an inverserelationship; a faster Cut leads to lower quality, and better quality requires a slower Cut.

Once you have selected Cut Quality, you can specify a file name and select the Generate Job File Button to export the final Cut File. You can now move this Cut File to an SD Card and then insert the SD Card into WAZER to begin the Cut.
