# Running a Program

Before loading a program into Mach3, the gcode needs to be generated. Use the CAM software of choice to make the program and then post the code using the generic Mach3 post processor. 

Recommended CAM programs to use are HSMworks, which is a part of Fusion360 or can be added to Solidworks, or Vetric VCarve. Any other CAM software with a Mach3 post processor will work as well.

## Step 1

Save gcode file to a known folder. 

Open Mach3 and have the machine powered on. 

Click File -> Load G-code or click the “Load G-code” button on the “Program Run” menu. 

File Explorer will open and select the desired file. Click Open.

Zero all axis’ to set the origin for the program.&#x20;

Click “Cycle Start” on the “Program Run” menu. The spindle should turn on and the machine will start to execute the program.
