How to set material home position

SETTING NEW HOME POSITION

Each program file contains a code that specifies the work home position.  This is usually done in the lower-left corner of the material (LLC), but for a variety of reasons it may be in another corner or somewhere else entirely.  The G-code that controls the home position is usually G54, but G55, G56, G57, and G58 may also be used.  VCarve will output the G54 code by default.  In order to teach the machine the location of the work piece that has been installed onto the machine spoil board, use the following steps:

1. Make sure there is a tool in the spindle

   1. If neccessary, load a tool into the spindle using the [MDI] mode (smaller tools are a little easier to use)

   2. Go to the [MAIN] screen and lift the dust boot by clicking the [BRUSH] button

2. Use either the [MPG] mode and pendant, or the [JOG] mode and the soft move buttons on the [MAIN] screen to move the gantry so that the center of the tool is over the appropriate location on your material

3. Navigate to the [OFFSET/SETTING] (F3) screen by clicking the button on the bottom of the screen or the F3 key on the keyboard

4. The X, Y, and Y2 fields for G54 need to be updated to the current machine position

   1. Cursor into the appropriate field

   2. Click [WORKPIECE COORD.] (F1) , click [APPLY MACHINE COORD.] (F1) again and confirm that you want to write the current machine position into the G54 field

   3. Repeat until the appropriate fields (X, Y, and Y2) have been set.  UNLESS YOUR WORK PIECE IS MOUNTED TO THE TOP OF ANOTHER SACRIFICIAL BOARD, DO NOT SET THE Z VALUE, IT SHOULD STAY 0.000.  If you have another sacrificial board under your work piece, then set the G54 Z-value to the measured thickness of your board (use the keyboard to input).
