26 -[[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. 
26 +[[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.--
27 27  
28 28  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 -**Advantages:**
30 +**Advantages: (Needs to be edited still)**
31 31  
32 -* Waterjet cutting is a cold cutting process, meaning there is no heat-affected zone (HAZ), so the material’s mechanical and microstructural properties remain unchanged.
33 -* It can cut a wide variety of materials, including metals, ceramics, composites, glass, and polymers, making it extremely versatile.
34 -* It allows for thicker material cutting compared to many other methods (including laser cutting).
32 +* Laser cutting tool heads never touch the material, leave fairly clean cuts, and are highly accurate and repeatable.
33 +* Laser cutting is far faster than manual cutting of the material, especially with repeated cuts in bulk materials.
34 +* Laser cutting allows for very small and intricate designs, which would be difficult or impossible with traditional cutting tools.
35 +* Laser cutting allows for much more efficient material usage than hand cutting in many cases.
35 35  
36 36  **Disadvantages: (needs to be edited still) **
37 37  
38 -* Waterjet cutting is generally** **slower than laser cutting, especially for thinner materials.
39 -* There can be a taper (slight angle) in the cut, especially in thicker materials, affecting edge perpendicularity.
39 +* Our CO2 lasers can't cut metals, or materials that reflect/poorly absorb its wavelength at powers below 130W.
40 +* 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.
41 +* In most cases, CO2 lasers have difficulty penetrating cleanly through materials greater than 1/4 inch thick.

133 -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.
134 -1. The next screen will have several options. Before doing anything else, **move the origin to the location of your choosing**
135 -1*. Move Origin - allows you to move the origin for the program to a location of your choosing. **DO THIS FIRST.**
136 -1*. Cut - sends you to the next screen where you must press the Start button to begin cutting.
137 -1*. Dry Run - Follows the exact cutting path of the program without firing the waterjet.
138 -1*. Check Extents - Outlines the bounding box of the area being cut
139 -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.
140 -1*. Cancel - sends you back to the starting screen.

146 -* 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.
147 -* 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.
148 -* It is recommended to keep the hoppers topped off
149 -* 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.**
150 -
151 -== Clean Up ==
152 -
153 -1. Remove your part and any excess material from the bed.
154 -1. Clean material and part(s) off by dunking them in the grit catchers/water bucket. **DO NOT wash grit down the sink.**
155 -1. Pull the grit catchers out and drain the excess water back into the tank.
156 -1. Once the majority of the water is drained, dump the grit into the orange 5 gallon bucket
157 -1. Place the grit catchers back into the machine.
