10.0 Making Parts with the CNC

–

2 Axis

10.1 Setting Up

Before you can run your program, you must set your absolute position in the DRO Mode. The

CNC will use this absolute position as a reference for running your program.

For the DPMEX2 product when run in 2 ½ axis mode (we display 3 axis on screen), you can
touch off your Z zero using any of the tools that are part of your program. You must, however,
make sure the tool in the spindle is the tool that the control thinks is in the spindle. The tool the
control thinks is in the spindle can be found in the status line.

10.2 Starting

After setting up in the DRO Mode, go into the Run Mode. You will see this screen:

The part number appears in the status line.

To start the program, select between START and START EVENT#.

•

START

–

starts running the program from the beginning.

•

START EVENT #

–

starts running the program from an event in the middle. If you press this key

you will be prompted to enter the event number for where to start.

10.3 Display Messages in Program Run

EVENT # and type:

This is the current or next event to be run.

REPEAT

: the number of the repeat for repeat events.

FEEDRATE

: the actual table feedrate.
