This CNC is the largest CNC we have in our lab for now. You are highly recommended to ask an ENTERPRIZE senior for help if you are using the machine for the first several times. It is a property belongs to HKUST ENTERPRIZE which is currently sharing with ISD.
0. Before the tutorial
If you are an ISD non RM student. For you won safety, you should only operate the machine in an ENTERPRIZE team member's presence. Ask the team member first before using it. If anything broke, you should inform ENTERPRIZE right away. You may email if you want to make sure that someone is in the lab. You are also required to use your own material. This CNC can cut board like raw materials like acrylic board or fiber board. You are not allowed to use the materials that belongs to ENTERPRIZE.
If you are an RM member, A senior member should in presence when you are operating for the first several time. You may operate the machine by yourself once the senior agreed.
You are suggested to wear goggles and mask when operating the machine.
ENTERPRIZE thanks you for your cooperation.
The CNC accepts .tap gcode file which can be generated by CAM software. An ArtCAM is installed on the computer beside the CNC which accepts vector files like the DXF file. We suggest you to use Solidworks to generate DXF files and import them into ArtCAM and generate gcode for the CNC machine.
2. Import DXF file to ArtCAM
-> Create New Model
-> Set the size to 480 * 480mm and set the origin to the left closer corner and press OK
-> "Vector" in menu -> import -> choose your DXF file and click OK if ArtCAM read it properly.
-> Move your imported vector to the left down corner.
3. Generate Toolpath
Go to the bottom left menu
-> Toolpath session
-> Click the first icon of 2D Toolpaths
-> Profile Side: Outside
-> Finish Depth: Your material thickness + 0.3~0.5 mm
-> Profiling tool: lab (Differ from what you are cutting, you may change the spindle speed, feed rate and plunge rate. Ask for help if you are not sure or do not know.)
-> Keep the others as default.
-> Select the vector you imported.
-> Calculate Now.
4. Save and import gcode to Mach3Mill
-> Menu -> Toolpaths
-> Save Toolpath As...
-> Click the black arrow
-> Save as G-Code (mm)(*.tap)
-> Open Mach3Mill
-> Load G-Code
5. Fix your raw material
Open the lid and keep it in status.
You may fix your raw material however you like. The picture below is a suggested way. Make sure you fix it firmly.
6. Set Zero
Use direction keys on the keyboard to control the spindle to move on the XY plane and "Page Up" & "Page Down" key to control Z-axis. You may press TAB to control the speed of movement. You are suggested to set X and Y zero first and then set Z zero. Remember to slow down when setting Zero Z.
7. Start Cutting
Move the spindle in the XY plane around the area to see whether the position of the part is suitable. Press Cycle Start to start cutting. Close the lid and stay around. If you heard unnormal noise or big banging sound, you should close the machine or stop the cutting as soon as possible.
8. After cutting
You should use a vacuum cleaner to clean up before collecting the part. Remember to close the lid while cutting and after cutting. Wash the parts using water after collecting it.
