====Training Checklist:====
  *Components Overview: CrystalMark DV-1, FlashCut CNC, camera, etching nozzle, part mount
  *Safety: hot printheads & bed, moving components
  *Job Setup
    *At FlashCut CNC and CrystalMark: Open air pressure valve -> turn on FlashCut CNC -> turn on CrystalMark DV-1 -> plug camera into computer -> fixture piece onto part mount
    *At the computer: export .dxf -> Zeroing 
    *After cut: inspect and remove piece -> vacuum area 
  *Part Removal Cleaning
    *Vacuum 
    *Sharps
  *Rates

====Safety Concerns====
  * Inhaling large aluminum oxide abrasive is hazardous. Wear a mask and safety glasses during use.
  * Silicon and glass pieces may have sharp edges. Handle with caution. 
  * Keep hands clear of etching during operation. Press any key on the keyboard in FlachCut CNC to stop operation.

 ====Common Mistakes====
  *DV1 not applying abrasive
    *Check to see if valve on air pressure tube is open (handle is parallel to tube)
    *Check to see if DV1 is switched on
  *FlashCut CNC 4 app is not connected
    *Ensure FlashCut CNC is on and reconnect with FlashCut CNC 4 by going to the "Controller" tab and selecting "Connect..."

 ====Safe Operating Procedures Review====
  - Open air pressure valve (to the left of FlashCut CNC)
  - Turn on FlashCut CNC
  - Turn on CrystalMark DV-1 (under table)
  - Plug in camera to computer (USB connection)
  - Fixture piece onto part mount

There are two ways to use the CNC: Etching with a .dxf file or manually etching: using .dxf file or manually \\
\\
If .dxf:
  - At computer: Load .dxf into the "DXF to G-Code Converter" application:\\ {{:dxf2gcode.jpg?direct&200|}}
  - For each shape in the display window, right click and select "Cutter Compensation" -> select either "Right Compensation" or "Left Compensation" depending on whether you want the positive or negative compensation (the blue outline is the new cut path)
  - Select "Export" -> "Optimize and Export Shapes" -> save as .ngc
  - open .ngc in "FlashCut CNC 4": \\ {{:flashcut4.jpg?direct&200|}} 
  - open "DinoCapture 2.0" (Used to monitor operation): \\ {{:dinocapture_2.0.jpg?direct&200|}} 
  - Place the acrylic plate on the crystalmark mount
  - Jog the nozzle into the hole
  - "Set" -> "Zero X and Zero Y"
  - Jog the CNC down to the surface of your piece
  - "Set" -> "Zero Z", be careful not to crash etching nozzle
  - After zero-ing the Z axis, move up in Z until Z is at 1.1 mm. This will be your cutting height. 
  - Select "Jog" and jog CNC to where the .dxf origin should be on your piece
  - "Set" -> "Zero X", "Set" -> "Zero Y" 
  - Note that origin is displayed in "DXF to G-Code Converter" (You can modify the origin in the software your .dxf was created): \\ {{:dxfzero.jpg?direct&200|}}
  - Use tape and/or turn on vaccum to fixture part (optional)
  - Begin etching : "G-Code" -> "Start"
  - Monitor operation
  - Select any key while in "FlashCut CNC 4" to stop operation

If manual:
  - open "FlashCut CNC 4": \\ {{:flashcut4.jpg?direct&200|}} 
  - open "DinoCapture 2.0" (Used to monitor operation): \\ {{:dinocapture_2.0.jpg?direct&200|}} 
  - Place the acrylic plate on the crystalmark mount
  - Jog the nozzle into the hole
  - "Set" -> "Zero X and Zero Y"
  - Jog the CNC down to the surface of your piece
  - "Set" -> "Zero Z", be careful not to crash etching nozzle
  - After zero-ing the Z axis, move up in Z until Z is at 1.1 mm. This will be your cutting height. 
  - Use tape and/or turn on vaccum to fixture part (optional)
  - Select "CrystalMark" switch and set to "on"
  - Let the Etcher create a through hole
  - Select "CrystalMark" switch and set to "off" 
  - In "DinoCapture 2.0", center the red lines about the hole
  - Jog X and Y to desired location, A hole will be made where the red lines intersect 
  - Select "CrystalMark" switch and set to "on"
  - Monitor operation
  - Select "CrystalMark" switch and set to "off" 

====Part Removal and Cleaning====
  * Jog CNC up in Z axis
  * Remove piece from mount
  * Blow aluminum oxide off part
  * Use ShopVac to vacuum excess aluminum oxide
  * Dispose of excess sharps in sharps container
  * Unplug camera, close air valve, turn off FlashCut CNC, turn off CrytalMark DV1

====Maintenance====
  * Vacuum area before leaving.

====Additional Information====
You can record your cuts in DinoCapture

====Troubleshooting====
If the Crystalmark is not cutting, the abrasive canister may be empty. Please
contact workshop staff to refill tool.
