21 21  While CO2 laser cutters can cut a variety of materials, we stock sheets of Acrylic and Birch Plywood in 12x24 inch sizes, and 1/8" and 1/4" thicknesses. Keep in mind these dimensions are nominal, and may not be precisely accurate.

23 -== About CO2 Laser Cutting ==
26 +== ==
24 24  
25 -[[Laser cutting>>url:https://en.wikipedia.org/wiki/Laser_cutting]] is the process of using a laser to vaporize a material, so that the laser beam cuts through the material. When this is combined with a CNC tool head and both power and speed are balanced properly, this process allows the user to create flat parts from sheets of material, using 2D CAD drawings.
28 += About the Waterjet =
26 26  
27 -There are several types of lasers, with different spectrum wavelengths and firing characteristics. We use [[CO2 lasers>>url:https://en.wikipedia.org/wiki/Carbon-dioxide_laser#Industrial_(cutting_and_welding)]] with power outputs of 130W and below. Lasers of this type and rating cannot cut metals, but are excellent for cutting organic materials and some plastics, as well as some other niche materials. Birch Plywood, Acrylic, thin silicone and buna rubber gaskets, organic materials such as leather, most fabrics and paper-based materials are among the materials that CO2 lasers can cut. Materials that should generally be avoided are highly reflective materials such as mirrors, materials that give off toxic fumes or particulates such as PTFE, ABS, Vinyl, and PVC plastics, and materials that cut poorly due to low wavelength absorption or other physical characteristics, such as HDPE and polycarbonate.
30 +[[Waterjet cutting>>https://en.wikipedia.org/wiki/Water_jet_cutter]] is the process of using a high pressure jet of water to cut a material.  --laser to vaporize a material, so that the laser beam cuts through the material. When this is combined with a CNC tool head and both power and speed are balanced properly, this process allows the user to create flat parts from sheets of material, using 2D CAD drawings.--

29 -**Advantages:**
32 +The waterjet has a hydraulic power output of 820 W. There are a variety of materials that the waterjet can cut, example of allowed materials include acrylic, agate, aluminum, borosilicate, brass, carbon fiber, ceramic tile, copper, gabbro, fused glass, graphite, granite, HDPE, marble, memory foam, mild steel, neoprene, polycarbonate, polyethylene, polyurethane, porcelain tile, silicone, spring steel, stained glass, stainless steel, titanium, and tool steel. Materials that are water soluble or shatter under high pressure are not suitable for waterjet cutting.
30 30  
34 +**Advantages: (Needs to be edited still)**
35 +
31 31  * Laser cutting tool heads never touch the material, leave fairly clean cuts, and are highly accurate and repeatable.
32 32  * Laser cutting is far faster than manual cutting of the material, especially with repeated cuts in bulk materials.
33 33  * Laser cutting allows for very small and intricate designs, which would be difficult or impossible with traditional cutting tools.
34 34  * Laser cutting allows for much more efficient material usage than hand cutting in many cases.
35 35  
36 -**Disadvantages:**
41 +**Disadvantages: (needs to be edited still) **
37 37  
38 38  * Our CO2 lasers can't cut metals, or materials that reflect/poorly absorb its wavelength at powers below 130W.
39 39  * Laser cutters create a fine cutting spot size by focusing the laser through a lens, and as a result, cuts can never be completely perpendicular to the material.
40 40  * In most cases, CO2 lasers have difficulty penetrating cleanly through materials greater than 1/4 inch thick.

47 47  
48 -The Long focal length lens in our large-format OMTech laser cutter allows for more efficient cuts in thicker materials. However, this comes at the cost of a slightly large spot size, and thus, less fine engraving abilities.
53 +**Username:** RPSpublic
49 49  
50 -Use the table below to input the correct values for your material. Note that for engraving, the thickness does not matter, because it won't cut all the way through. We also have sample engravings at various settings in the RPS if you would like to change the depth or darkness of the engraving. Keep in mind that the depth and color might not be exact, as they depend highly on laser focus and various other environmental parameters that cannot be controlled.

95 += Machine Setup =
96 +
97 +== Turning Machine On ==
98 +
99 +1. Place SD card with part file into the right side of the wazer jet machine. **(SD cards are not provided)**
100 +1. Twist the E-Stop button to where it releases, the screen should begin to turn on.
101 +1. Check that the button on the bottom right of the machine is set to "On" (if screen is still not turning on, consult a staff member)
102 +
103 +== Setting Up ==
104 +
105 +1. On the starting screen there will be two options, "Select Cut File" and "Setup & Maintenance". Press the OK button to Select the Select Cut File option.
106 +1. Scroll down until the cursor is next to the file you created earlier, and hit OK
107 +1. Loosen the Nozzle securing knob, pull the nozzle up, and retighten the nozzle securing knob, press OK to home the nozzle
108 +1. Fill the grit hopper on the left side of the machine, hit OK
109 +1. Check to make sure the blue water valve is in line with the vertical pipe, hit OK
110 +1. Secure the material to the cut bed using the screws and a screwdriver, hit OK
111 +1. Now that the arrow keys can be used to move the nozzle over the material, remove the plastic cover off of the cutting head.
112 +1. Loosen the nozzle securing knob, and place the tab side of the plastic cover underneath the nozzle.
113 +1. Lower the nozzle until it makes contact with the plastic tab, and tighten the nozzle securing knob and place the plastic cover back on top of the cutting head. Hit OK.
114 +1. The next screen will have several options. Before doing anything else, **move the origin to the location of your choosing**
115 +1*. Move Origin - allows you to move the origin for the program to a location of your choosing. **DO THIS FIRST.**
116 +1*. Cut - sends you to the next screen where you must press the Start button to begin cutting.
117 +1*. Dry Run - Follows the exact cutting path of the program without firing the waterjet.
118 +1*. Check Extents - Outlines the bounding box of the area being cut
119 +1*. Restart cut - if the cut fails or stops in the middle, this will restart the program in the Dry Run state and will allow you to resume the cut at any point along the program.
120 +1*. Cancel - sends you back to the starting screen.
121 +
122 +== Run Part ==
123 +
124 +***You must remain with the machine for the entirety of the cut* **
125 +
126 +* It may be necessary to refill the water in the machine before running. Use the white 3 gallon bucket to pour more water into the tank directly. The water level should sit right below the surface of the bed.
127 +* Monitor the level of the grit while the part is running, if it's running low, machine will automatically stop the cut and shut off.
128 +* It is recommended to keep the hoppers topped off
129 +* If water starts pouring out from under the hoppers, the machine is having a backflow problem, **SHUT IT OFF with the E-Stop and notify RPS Staff.**
130 +
131 +== Clean Up ==
132 +
133 +1. Remove your part and any excess material from the bed.
134 +1. Clean material and part(s) off by dunking them in the grit catchers/water bucket. **DO NOT wash grit down the sink.**
135 +1. Pull the grit catchers out and drain the excess water back into the tank.
136 +1. Once the majority of the water is drained, dump the grit into the orange 5 gallon bucket
137 +1. Place the grit catchers back into the machine.
