91 -**Centerline:** Part will be cut directly on the lines of your part.
86 +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.

93 -**Inside:** Part will be cut inside the designated lines by a user given offset.
88 +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.

102 -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.
106 +Settings can be changed within Lightburn or on the physical OMTech Laser in the highlighted portion on the display screen. Please consult with a technician before changing speeds and power on the machine.
103 103  
104 -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.

116 -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.
117 -1. Scroll down until the cursor is next to the file you created earlier, and hit OK
118 -1. Loosen the Nozzle securing knob, pull the nozzle up, and retighten the nozzle securing knob, press OK to home the nozzle
119 -1. Fill the grit hopper on the left side of the machine, hit OK
120 -1. Check to make sure the blue water valve is in line with the vertical pipe, hit OK
121 -1. Secure the material to the cut bed using the screws and a screwdriver, hit OK
122 -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.
123 -1. Loosen the nozzle securing knob, and place the tab side of the plastic cover underneath the nozzle.
124 -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.
125 -1. The next screen will have several options. Before doing anything else, **move the origin to the location of your choosing**
126 -1*. Move Origin - allows you to move the origin for the program to a location of your choosing. **DO THIS FIRST.**
127 -1*. Cut - sends you to the next screen where you must press the Start button to begin cutting.
128 -1*. Dry Run - Follows the exact cutting path of the program without firing the waterjet.
129 -1*. Check Extents - Outlines the bounding box of the area being cut
130 -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.
131 -1*. Cancel - sends you back to the starting screen.

137 -* 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.
138 -* 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.
139 -* It is recommended to keep the hoppers topped off
140 -* 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.**
167 +* None
141 141  
142 -== Clean Up ==
169 +Once the job has concluded, allow the fumes to be vented for a minimum of 10 seconds. Please note that woods will have charring which is not harmful but may transfer to your hands or anything else it touches. If desired, you may sand the wood with the sandpaper we have in stock or use a sander. For acrylic sheets, peel off the protective film once ready for personal/project use.
143 143  
144 -1. Remove your part and any excess material from the bed.
145 -1. Clean material and part(s) off by dunking them in the grit catchers/water bucket. **DO NOT wash grit down the sink.**
146 -1. Pull the grit catchers out and drain the excess water back into the tank.
147 -1. Once the majority of the water is drained, dump the grit into the orange 5 gallon bucket
148 -1. Place the grit catchers back into the machine.

177 +Once the job has concluded, allow the fumes to be vented for a minimum of 30 seconds. Please note that rubber materials will char as well and it is best practice to wear gloves while handling them. Rinse the rubber cuts under water to wash off as much charred edges as possible.
