#Select the "Line" tool from the "Draw" menu on the left of the screen and create a 2" square with a 1" square notch in the top right corner. To do this, click anywhere on the screen to start the first line. This will bring a popup "Specify Dimensions" box where you will enter 2 into the "Rise (dy)" box. This will create a 2" vertical line.  Select the "Line" tool again at the top of the first line and enter 1 into the "Run (dx)" box. This will create a 1" horizontal line to the right. Repeat this process until the box looks like this. The last line at the bottom can by created by selecting both open edges with the "Line" tool.

'''Tool Paths''':

# Zoom in closer to the circle. Select the "Lead i/o" tool from the "Draw" menu on the left of the screen. Select the bottom edge of the circle and move the cursor upwards and click to create a lead in and out from the center of the circle. This will tell the water jet to cut on the inside of the circle. Looking at this picture, you can see that one line is longer than the other. This longer line is the lead-in line. The nozzle will penetrate the material from the beginning of the long line and work its way down to the bottom of the circle. Once the nozzle hits the bottom, it will start counter-clockwise because the lead-in line is positioned at a slight angle to make counter-clockwise and easier direction than clockwise. This is how you tell the nozzle which direction to cut.

# Select the "Line" tool and connect the long, lead-in line of the box to the short, lead-out line of the circle. This is a traverse line telling the machine to move from the circle to the box after it has finished cutting the circle.

# Use the line tool and click on the long, lead-in line for the circle.  Place the other end of the line so that it is at least 1/8" past both the left and bottom edge of the part. This will be the origin for the part and the cut. It should look something like this.

# Now you get to decide the quality of each cut. Select the button at the bottom of your screen labeled "Quality". You should see a range from 1 to 5, a Traverse, and Lead i/o. The range of 1 to 5 will change the machines cutting speed. The higher quality is 5 (slower) and the lowest quality is 1 (faster). Choose a quality of 5 for the circle by clicking "5" and then selecting every part of the circle. Do the same for the outer edge but with a quality of 1. Your part should look like this. Leave the traverse lines as green. You don't want them to cut there.

# A window will popup showing the tool path. Zoom in closer to your part and inspect where the tool path is. The program will display cuts as a thick red line. Make sure that these projected cut lines are on the proper side of the line that you specified. If all looks well, hit "save" on the bottom, left of your screen.

* Check the pressure gauge to verify that the water pressure is 40 psi or greater

* Fill the tank to the top of the metal ribs

# Fill the tank to the top of the metal ribs with the water hose on the right side of the machine.

* Check the garnet hopper. If it is low, fill it up.

* Zero the water jet cutter head

* Position the nozzle between two of the metal ribs, close the lid, and test the nozzle

* Open the lid, position the material in the machine, and clamp it down

# Position the nozzle between two of the metal ribs, close the lid, and test the nozzle using MAKE. When closing the lid, the support bar on the right side of the lid must be lifted otherwise it will not close. There are two things that should be checked when performing the nozzle test. First, check that the water is flowing through the nozzle. This seems obvious but is necessary because the nozzle can get clogged. Second, check that there is abrasive flowing through plastic tube. It flows quickly but can be identified by a sparkling in the tube as it flows.

* Load the cut file, select the material and enter its thickness

# Open the lid, position the material in the machine, and clamp it down. To clamp down the material, first slip the clamping post into the slot on the crossbar and the twist clockwise to tighten it into place as seen in the series of figures below. Then slide the material clamp over the post and push down to tighten. Repeat this process with any other clamps that are needed to secure the material.

* Set the origin point for the machine

# Load the cut file into MAKE, select the material being cut, and enter its thickness.

* Position the nozzle over the material and adjust the height of the nozzle very carefully making sure the adjustment tool has enough room to wiggle up and down

# Set the origin point for the machine in MAKE.

* Continue to fill the tank with more water so that there is about 1/8" of water above the surface of the material

# Position the nozzle over the material and adjust the height of the nozzle very carefully making sure the adjustment tool has enough room to wiggle up and down. Do this by loosening the knob on the side of the nozzle with one hand while holding the nozzle with the other. Be very careful not to drop the nozzle onto the material as it could be broken. Slide the adjustment tool, pictured below, under the nozzle and then carefully lower the nozzle onto it. Tighten the knob once the nozzle is positioned correctly.

* Execute a dry run making sure that the nozzle will not collide with anything

# Continue to fill the tank with more water so that there is about 1/8" of water above the surface of the material.

* Flip the orange rubber cone down, run the cut, and watch out for:

# Execute a dry run making sure that the nozzle will not collide with anything.

*# Material excess floating up; pieces of cut material floating up and getting wedged between the nozzle and other material or clamps could cause a catastrophic failure. Pause the cut if you think this may happen.
