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:
- 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
- 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”
- Begin etching : “G-Code” → “Start”
- Monitor operation
- Select any key while in “FlashCut CNC 4” to stop operation
If manual:
- Jog the CNC down to the surface of your piece, use a piece of paper to shim the etching nozzle and piece
- “Set” → “Zero Z” when paper is difficult to move, be careful not to crash etching nozzle
- Select “Jog” and jog CNC 1.2 mm up in the Z axis
- 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
- ShopVac area
