1 1  Much like 3D printers, waterjet cutters need a slicing program to convert vector files into movement instructions for a given machine. Our program of choice is [[WazerCam>>https://wam.wazer.com/wazercam]], as it's UI is intuitive, the most important settings are readily available, and it's easy to set up for new users.

5 -=== Opening WazerCam ===
5 +--Versions of Lightburn for Windows, Linux, and Mac OS are available at their [[downloads page>>url:https://lightburnsoftware.com/pages/download-trial]]. Every **new** user is allowed a free 30 day trial period with full access to all features. After that, a **lifetime** license key can be purchased for $120 [[here>>url:https://lightburnsoftware.com/products/lightburn-dsp]]. You can always access Lightburn on the computers in the RPS for free. Students with a reservation for a laser cutter may also come in to prepare their file on one of our workstations beforehand. During laser-training, we will walk you through using Lightburn, and we are always here to help should any issues arise.--

23 -The following metrics can be adjusted within WazerCam:
31 +Job origin: **Back Right (upper right)**
32 +Start From: **User Origin**
24 24  
25 -**Rotation:** the angle which the part needs to be rotated to
34 +[[image:lightburn_2.png]]
26 26  
27 -**X & Y positions:** The top left of the screen represents 0. All X and Y movements are from the top left of your part. 
36 +Download the **material settings** with this link: [[Lightburn Library Material Settings>>url:https://wiki.rapidprototypingstudio.com/machines/lightburn_library_material_settings.clb]]. You can import these settings to Lightburn as part of the setup process. Click //Library// in the bottom right then click //Load// to load this file. All material settings should import to your library. To change the material type, click the desired material and click //Assign//.
28 28  
29 -**Scale:** Scale of parts can be changed by any magnitude
38 +If you will be using Lightburn more in the future, "linking" materials to certain colors has proven to be useful. Highlight the shape and click //Link//. This will allow you to assign colors to different materials, thicknesses, and cuts/engravings.
30 30  
31 -**Height & Width**: Similar to scale, height and width can be changed independently.
40 +== Usage ==
32 32  
33 -(Be aware of total physical space that the waterjet will occupy on a material, taking into account the width of the cut itself (kerf) )
42 +Compared to 3D printing, the slicing process is quite simple, as there are far less parameters to take into account. Despite that, using the laser still requires utmost caution, as improper settings will lead to ineffective cutting at best, and will start a fire at worst.
34 34  
35 -[[image:1772478615037-166.png||height="266" width="554"]]
44 +We have a [[list>>doc:CO2 Laser Cutters.WebHome]] of recommended laser settings for a variety of materials. For materials not on the list that do not produce any [[toxic gasses>>url:https://cpl.org/wp-content/uploads/NEVER-CUT-THESE-MATERIALS.pdf]], we typically run some tests using small (10x10mm) square test cuts, adjusting laser power/speed until a satisfactory cut is produced.
36 36  
37 -== Materials Selection ==
46 +We recommend watching the many great [[video tutorials>>url:https://www.youtube.com/watch?v=KdqMW3F_iIU]] that demonstrate basic Lightburn usage if you would like to learn more.

39 -Using the first dropdown menu, select the material category. Using the second dropdown menu, select the specific material you are cutting. If the specific material is not listed, consult an RPS studio staff member. Once category and material type are selected, input the material thickness in either millimeters or inches.
49 +=== The basic premise: ===
40 40  
41 -[[image:1772478775055-319.png||height="264" width="550"]]
51 +* Load SVG or DXF vector file **in millimeters**. This will most likely come from an engineering drawing in [[Solidworks>>https://wiki.rapidprototypingstudio.com/xwiki/bin/view/Exporting%202D%20Files%20From%20Solidworks/]] that must be exported in millimeters as well. **Always double check units once imported**.
52 +* Adjust laser cut power & speed and number of passes in the bottom right corner based on the [[OMTech laser settings>>url:https://wiki.rapidprototypingstudio.com/Machines/CO2_Laser_Cutters]].
42 42  
43 -== Cutting Path Adjustments ==
54 +​​​​​​​[[image:lightburn_img.png]]
44 44  
45 -Change the cutting path to match the design of your file.
56 +* - Cut: set mode to //Line//
57 +- Engrave: set mode to //Fill//
46 46  
47 -**Outside:** Part will be cut outside the designated lines by a user given offset.
59 +To change the paths' order of cutting, select the shape you want to cut first and color it differently. A new cut layer will appear on the right. Move that new color to the top of the list, which will code this cut as the first part of the job
48 48  
49 -**Centerline:** Part will be cut directly on the lines of your part.
61 +​​​​​​​[[image:lightburn_img2.png||height="406" width="745"]]
50 50  
51 -**Inside:** Part will be cut inside the designated lines by a user given offset.
63 +* To preview the job, press //Alt+P// which will show the exact path the laser will take. A good rule of thumb is to start with smaller, inner-most cuts and make the large, outer cuts last. This will ensure clean, quality cuts and prevent warping of inner cuts that still need to be made.
52 52  
53 -**No Cut:** Lines will not be cut
54 54  
55 -[[image:1773683954161-404.png||height="254" width="527"]]
56 56  
57 -== Tabs and Leads ==
67 +​​​​​​​[[image:lightburn_img3.png||height="581" width="726"]][[image:https://wikijs.rapidprototypingstudio.com/learning/lightburn_img4.png||height="577" width="722"]]
58 58  
59 -Tabs are a connection point between your part and where it's being cut on the material. Tabs keep your part in place while being cut, and improve the overall cut accuracy by preventing your part from popping up or out of place. The default settings are that all cut paths receive a single tab, with the size based on the material, however tabs can be manually adjusted as well.
60 60  
61 -A Lead refers to the distance that a cut will made away from the Cut Path. This is done to make sure that the pierce at the start of a cut does not remove any excess material on your part. The Lead’s location and size are designated with a blue indicator.

67 -== Cut ==
68 -
69 -There are three setting selections for cut quality: Coarse, Medium, and Fine. Cut rate and cut quality have an inverse relationship, a faster Cut leads to lower quality, and better quality requires a slower Cut. The page includes cut details such as rate, time, abrasive use, cut cost, and cut extents.

71 -This is the final step in file preparation, and file naming and downloading are done at this stage. A virtual cut path simulation will also be available for viewing.
