89		-Outside: Will cut outside the lines of your part by a user given offset.
	85	+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.

91		-Centerline: Will cut directly on the lines of your part.
	87	+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.

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.**
	112	+All settings are preset within the Dremel's IP address site.

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

	168	+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.
