 ====Cutting with the Wazer Waterjet====
-  - **Check water bed level**. Make sure the water level is nearly up to the top of the bed (within 2 mm or so). If there is not enough water, add some more with the rubber hose connected to the DI water. Insufficient water levels will not allow the waterjet to turn on.
+  - **Open WAM**. This is where you will create the toolpath for your job.
-  - **Check Abrasives**. Make sure the unused abrasives are filled to the bottom of the sieve, and make sure the used abrasives bucket is emptied.
+    - Upload your DXF or SVG file onto the software.
-  - **Open WAM**. This is where you will create the toolpath for your job. Upload your DXF or SVG file onto the software, and export it via SD card.
+    - Scale and position your parts. Importing the file may result in a change in dimensions, so double check the measurements are still the same.
-    - Scale and position your material. Importing the file may result in a change in dimensions, so double check the measurements are still the same.
+    - The grid in the software matches the plastic cut bed in the Wazer. Move your part(s) so that they will fit within your material.
-    - The waterjet has the origin set to the top left corner of the machine. The top-left corner of the toolpath inserted will become the new origin and where the nozzle will move to after the homing sequence.
     - Select the material you are working with and select the corresponding thickness. If you do not see the material you are cutting, contact a wizard.
-    - Select the cutting path offset. This will allow you to control how the kerf will affect your cut.
+    - Select the cutting path offset. This will allow you to control how the kerf will affect your cut (don't change the default unless you know how to adjust it).
     - Select your tabs and leads. This will prevent vibration/pop-ups, which will jam the waterjet and ruin the cut, and also improve accuracy.
+      - Usually 2-4 tabs is enough for most materials and thicknesses.
+      - Tab thickness should be proportional to material thickness, a good rule of thumb is for your tab thickness to be 30-50% of your material thickness. For very thin materials, we recommend a minimum tab thickness of 0.05"
     - Select the cut quality. This will determine time for each job and the amount of abrasive used.
-  - **Turn on Water and Power Supplies**. Turn on the water by turning the sink on. If there are any signs of leaks, turn off the water immediately and notify a wizard. Make sure the power supplies have a green light on. If not, try pressing reset.
+      - Fine usually gives the best results
-  - **Insert SD Card, Turn On, and Select Cut File**. Make sure you insert the SD card before turning on the waterjet! The power switch is located on the underside of the right, towards the front. Select your cut file.
+  - **Check water bed level**. Make sure the water level is nearly up to the top of the bed (within 2 mm or so). If there is not enough water, add some more with the rubber hose connected to the DI water. Insufficient water levels will not allow the waterjet to turn on.{{ :tools:wazer_waterjet:img-1579.jpg?200|}}{{ :tools:wazer_waterjet:img-1578.jpg?200|}}
-  - **Lift the Nozzle and Home**. This will prevent the nozzle from crashing into anything when homing. Click "OK" to start the homing process. The nozzle will move to the top-left corner of your material's toolpath.
+  - **Check Abrasives**.
-  - **Place material on bed**. Fixture your material with fasteners. For brittle materials, do not over-torque the fixture. Make sure your fixtures are not in the way of the toolpath.
+     - Fill up the abrasive tanks to the top of the sieve (drawer on the left side of the waterjet).
+       - The bucket of abrasive is under the sink. The backup bucket(s) are on the right of the F270.
+     - Empty the used abrasive tanks into the trash (under the cover closest to the front inside the wazer).
+  - **Turn on Water and Power Supplies**.{{ :tools:wazer_waterjet:img-1580.jpg?200|}}
+    - Turn the sink handle on, you should see the filter water pressure jump up. Ensure that the pressure gauge is in the green, if it's not there isn't enough water flow and you CANNOT CUT.
+      - If there are any signs of leaks, turn off the water immediately and notify a wizard.
+    - Check that the drain hose is going into the sink.
+    - Turn on the wazer and pump by pressing the "reset" button on the power blocks (bottom right and top left relative to the wazer).
+  - **Insert SD Card, Turn On, and Select Cut File**. The power switch is located towards the front on the right underside of the wazer. Select your cut file. Go through the steps on the screen.
+  - **Lift the Nozzle and Home**. This will prevent the nozzle from crashing into anything when homing.
+    - Untighten the knob on the nozzle and raise the nozzle to the highest position and re-tighten the knob.
+    - Click "OK" to start the homing process. The nozzle will move to the top-left corner of your material's toolpath.
+  - **Place material on bed**. Fixture your material with fasteners.
+    - Use a minimum of 4 screws with washers and tighten them down only with a screwdriver
+    - For brittle materials, do not over-torque the fixture. Make sure your fixtures are not in the way of the toolpath.
     - Line up the top left corner of the material with the center of the nozzle.
-  - **Set Nozzle Height**. Jog the nozzle over the material. This will not affect the starting position for the cut. Place the Nozzle Height Tool underneath the nozzle, and gently lower the nozzle onto its flange. Tighten the knob and replace the Nozzle Height Tool at the top of the nozzle. Press "OK".
+  - **Set Nozzle Height**.
-  - **Perform a Final Check**. Click Check Cut Extents or Dry Run in order to check where the toolpath will run into without actually cutting anything.
+    - Jog the nozzle over the material. This will not affect the starting position for the cut.
-  - If everything is OK, click the play button and your part will begin to print.
+    - Untighten the knob on the nozzle and retrieve the Nozzle Height Tool (stored on top of the nozzle - black plastic piece).
+    - Place the Nozzle Height Tool underneath the nozzle and gently lower the nozzle onto its flange.
+    - Tighten the knob and replace the Nozzle Height Tool to the top of the nozzle.
+  - **Perform a Final Check**.
+    - Click Check Cut Extents or Dry Run in order to check where the toolpath will run into without actually cutting anything.
+    - If everything is OK, click the play button and your part will begin to print.
   - **YOU MUST NOT LEAVE WHILE PART IS BEING CUT**
-  - Once the print has been completed, open the lid, lower the bed and remove the part. Beware of sharp edges. Make sure all pieces of material are removed from bed.
+  - Once the print has been completed, open the lid, unscrew your material, and remove the part. Beware of sharp edges. Make sure all pieces of material are removed from bed.
-  - **Tank Cleaning and Maintenance**. Run a tank cleaning cycle if you are not making another cut for a while or if the machine has been running for more than 4 hours. This will collect abrasive that is at the bottom of the tank. There will be some abrasive that accumulates from the door windows and on the bellows. If they are not coming off easily, let them dry and then sweep.
+  - **Turn off the printer**
-  - **Turn off the printer** and leave the lid open.
+    - Press test on both the power supplies.
+    - Close the sink lever and ensure that the pressure drops in the filter gauge (it won't go all the way down to to 0)
+    - Leave the wazer lid open.
