Right click on Quality > All > 5. To set your part to the highest quality cut. Your part will turn blue (not picutred)
Click the AutoPath command to generate a toolpath. Your cuts will turn pink, lead Lead in/out outs will be orange , and traverses (nozzle moves but isn’t cutting) will be green.
...
You can move or swap the direction of lead ins/outs by right clicking on the Lead i/o tool.
Click Set Zero and select the point on the grid where you want your part origin to be. It will show up as a white + sign.Ctrl s to save and leave the name and location as default (this saves the toolpath setup in case you need to go back and change something later. it does not change your dxf)
Click on the Post button on the right and then select which of the two end points of the toolpath that you want to be the start.
Make sure that the red highlighting (cut) is on the correct side of the pink lines (your .dxf lines)

The starting point that you selected will also be the zero/origin point that you set in the waterjet. I normally will delete the two long green lines (start and end points) in the above screenshot to make them a bit shorter and set the starting point to a convenient location to reference on the stock in the waterjet.
Click save. This will create a .omx file save in the same folder where your .dxf is saved. Put this .omx file on a USB drive and bring to the waterjet.
Cut on the Machine
| Warning |
|---|
if you ever see water coming out of the garnet tube on the left side near the hopper of garnet stop the machine right away |
Message Abby Speckhals in slack to get trained on the waterjet in-person. The steps below can serve as a refresher for people who are already trained.
Turn on the machine with the switch on the right side.
...
Make sure the garnet tube is connected to nozzle head and flip yellow guard down.
...
Close lid
RunBegin Machining > Start. Make sure you can see the red garnet going through the tube from the hopper into the machine. (If you don’t see this and the part is not being cut, follow steps below for unclogging the nozzle.
...
Rinse part and take it out
...
Tell Abby or Jeffrey Speckhals if this happens so someone can help if its you’re first time encountering this problem
Disconnect garnet tube from nozzle head and from hopper
Blow air through the garnet tube from the hopper side to the nozzle side to get any water out
Pull yellow guard down and off of the nozzle
Use green-handled in-line torque wrench to loosen thumb screw and wiggle the nozzle out
Make sure machine head is positioned between two slats of the bed. Run a cutting head test to clear out head of waterjet. You should still have the garnet line disconnected so just water is pushed through.
Reinstall nozzle upside down in the head of the machine. Tighten thumb screw with the torque wrench.
Run another cutting head test to clear out the nozzle. Make sure the flow appears uniform.
Reinstall nozzle correctly in the machine. Reconnect the garnet tubes.
Run a final cutting head test making sure you see garnet being sucked through the tube from the hopper.
If you still do not see garnet in the tube, there is probably a water clog at the bottom of the hopper. Take the hopper off of its mount and dump the garnet on the top that is definitely dry back into the bucket of extra garnet. Discard the small amount of garnet at the bottom that might be wet. Use the air gun to blow out the metal attachment at the bottom of the hopper.

The more plies in a layup, the greater the risk of delamination during waterjetting. If this is a concern, drill starting holes prior to waterjetting to reduce the risk. |
