Setting up the probe tool

This manual covers the basic setup of the probe tool that can be used in a number of myCNC profiles and applications in order to determine an exact position of the part on a milling machine. The probe can find edges, corners, hole centers, and more.

Connecting the probe sensor to the myCNC board

A Vers PR probe is currently being sold as part of some myCNC kits. The sensor looks like the image below:

In order to set up this probe sensor with a myCNC controller, please consult the diagrams below. Note that while the setup is shown in one particular configuration on the ET7 myCNC control board, it can be replicated on other boards and in other connection configurations as well:

NOTE: The IN group of connectors used in this example is Group 4, as shown in the diagram below. Therefore, in this particular example, Jumper 4 is closed in order to supply power to Group 4. In your particular setup, please close the proper jumper for each respective group.

Setting up a Probing Wizard in Mill profile

In order to properly set up a probe system on a mill profile from scratch on your machine (especially if the software has not, for any reason, been updated to its latest version) please check the following:

1. In CNC Settings > PLC > Hardware PLC, check that the command TRIG04 is created. The program should contain the following code:

main()
{
  gvarset(9122,1);  timer=30;do{timer--;}while(timer>0); //show message

  if (gvarget(6060)!=0x57)
  {
    message=PLCCMD_MOTION_BREAK;
    timer=30;do{timer--;}while(timer>0);
  };

  exit(99);
};

2. In CNC Settings > Probing Wizard > Probing Macro Wizard, click Generate All Probing Macros and Generate PLC Probing procedure M288. Among other settings, this generates the necessary windows for the popup screens of the probe sensor (popups 20, 21 and 22). mill-probe-software-002.jpg

3. If you want to set the particular port that you are using for your sensor, go to Go to CNC Settings > Probing Wizard > Probing Config and click the Enable Probe sensor protection button after setting the particular port desired (Port 9 for this example). This setting will be automatically mirrored in the CNC Settings > Triggers/Timers window. mill-probe-software-003.jpg

4. Double-check the TRIG04 procedure from Step 1, and edit it back to the code above if it had been changed (this can occur on older versions of the software).

The probe wizard setup should now be complete.

Using the probe sensor in myCNC software

After the probe has been successfully connected, it can be used from within myCNC software. The probe sensor window can be opened from the main profile screen, and looks like this:

The full description of buttons for this window can be found in the screen description manual.
