Getting Started
The process for creating a part using the mill is:
- Design/create the part using a CAD program like OnShape, SolidWorks, FreeCAD, or Fusion360.
- Generate instructions to tell the mill how to move to create the part. These instructions are called G-code because many of the instructions start with the letter 'G'.
- Load the G-code onto the PC by the mill
- Install the cutting tool into the mill. This must be the same one you specified when you created the G-code.
- Turn on the mill using the power strip next to it labelled "Mill"
- Start the CNC12 mill program on the PC
- Clear the reset button in CNC12 by clicking it
- Move the mill to the starting location on the part
- Click the "Home" button in CNC12
- Load the G-code file into CNC12
- Start the spindle and set the RPM
- Click "Cycle Start" to have CNC12 execute your G-code.
