Install dowels (or 1/4" tool shanks will do, just be careful not to cut yourself).Using a 1/4" end mill, run the calibration test program to create four dowel hole locations.
Download the Vectric or Fusion calibration project (above under Source Files) and create (or use DXF to create) the calibration test toolpath files (operations are pre-configured).Home the machine using the Home XYZ Axes button in Mach4 (if this is your first time, reference our Mach4 Users Guide).For Standard CNC and Benchtop CNC machines, leaving the sensor exposed 3/4" through the plate is typical.Setting the sensor flag depth will be the same regardless of machine size. For PRO CNC machines, refer to Step 1.6.2.6 in the assembly instructions.Install the Y1- and Y2- sensors (or sensor flags) to the same depth.Once this is performed, the machine can be re-homed and automatically re-squared by using the Home XYZ Axes button in Mach4. This is the procedure that we use and recommend. There are multiple methods that will test if a gantry is square. By adjusting these two sensors you can adjust the squareness of the gantry to your machine table. They synchronize their motion and auto-square your gantry by homing to their respective home sensor. Our machines use a dual gantry drive architecture, meaning they are independently driven axes moving each side of the gantry. If you purchased your electronics prior to this date, your Plug and Play CNC Control System is labeled "Y" axis (now the Y1 axis) and "Slaved" axis (now the Y2 axis). The nomenclature used to describe the dual-driven Y axis changed in April 2021 to "Y1" axis and "Y2" axis.
