The ISO file programming page allows to manage and start the workings through .pgm files created previously through CAD-CAM programs.

List

The ISO program list, initially empty, contains all the ISO programs that can be executed sequentially.

Buttons

There are a series of buttons for the list management.

	Open File Opening of resources explorer for the creation of a list of files to be executed.
	New ISO list Adding a file to the list of files to execute.
	Add Pause Addition of a pause to the list of files to execute.
	Remove selected element Deletion of a file from the list of files to execute.
	Empty list Deletion of all the files list to execute.
	Move selected element higher Up movement of the selected ISO file within the list of files to execute.
	Move selected element lower Movement toward the bottom of the selected ISO file inside the list of files to execute.

In the lower part we find also the two buttons relative to the execution modes of the programs:

	Manual / automatic Defines if the machine state is manual or automatic.
	Single / Next Automatic Defines if the start of the next program will be done automatic or not.

Open file

The pressure of this button will make appear a window 'Open File' as shown in the following image:

This window is divided in the following components:

• List Files

  • include all files in format .pgm present in the directory currently selected

• Buttons between the Files list and the Selected Files list

• Selected File List

  • List initially empty

• Preview Selected file

  • Shows a preview of a .pgm file selected from Files or from Selected File

• Bottom bar and search filter

Central buttons, placed between the 'FILES' list and the 'SELECTED FILES' list

	Select element Move the selected element of the FILES list to the SELECTED FILES list.
	Remove element Delete the selected element from the SELECTED FILES list.
	Insert Pause Add a pause in position next to the selected item in SELECTED FILE.
	Move selected element top Move the selected item one position higher in the SELECTED FILES list.
	Move selected element low I move the selected item one position lower in the SELECTED FILES list.

The content of the lower bar is reported here.

	Clean search filter Empty the text bar located to the left of this button.
	Sorting by last modify Apply a sorting of the files present in FILES based on the most recent changes (first image) or least recent (second image).
	Alphabetical Sort Apply a sort of the files present in FILES based on alphabetical order or reverse alphabetical order.
	Viewing key file Viewing all files with .pgm extension present in the USB drive.
	View ISO folder Visible the content of the ISO folder.
	Viewing contents Display the disks present on the computer and the Desktop folder.
	Remove file Activate the delete file mode, which allows the deletion of .pgm files from FILES.
	Enable/Disable copy Allows to enable/disable the copy function (copy the selected file in the ISO folder).

ISO Program Code

The program ISO code running is displayed in this window:

Buttons

In this section of the ISO program we have the following buttons and relative functionalities.

	Timer and Reset Indicates the execution time of the entire .pgm File. By pressing the button the Timer is reset.
	View ISO Activate or deactivate the ISO preview viewing.
	Block search This button will be shown only after having loaded in the list at least a program, it allows the search block by row.
	Block search for line This button will substitute the 'Block search' button, after the latter is pressed. It is given the possibility to the operator to search a specific row of code in a small window that will be displayed on the screen. Subsequently to the insertion of a number in the 'Row number' field and pressing the 'Go to' button, the ISO program code view will be moved to the desired line, or to the last available line if the composed number exceeds the number of lines present in the selected ISO program. It is possible to conclude the search of a block, and restore the visibility of the 'Block search' button, via the Pressure of the Close button:
	Dry Run function (Activated / deactivated) Selecting this working mode, is possible execute a working at maximum speed of the machine. WARNING! The use of this function obliges to not use ANY type of material during the working because during the execution the speeds are not respected within the ISO program; the CNC will execute the entire program at the maximum nominal speed achievable with interpolated axes.
	ISO test function (Activated / deactivated) With this option, it is possible to perform the test of the loaded file to check that there are no syntax errors. Press the 'START CYCLE' button and the machine will virtually execute all lines of code without moving the axes.
	Suction cups panel Access to the panel for the handling of the vacuum.
	Save Upon pressing the button appears a keyboard that allows to modify the .pgm File loaded, before sending it to execution.

Block search

During the execution of (.pgm) files, the block search function could be useful to reposition the tool to the point where the machine has interrupted the program execution, in case of tool blockage inside the material or other types of blockage.

Once the button has been pressed, you can search for the line from which to continue/start the working, via the line number by pressing the 'Search block by line' button or by scrolling the file via the scroll bar placed next to the file and selecting the desired line.
After having selected the point of the program from which the machine will continue the interrupted work, press the 'Start cycle' button; the machine will recalculate all the lines of code in the .pgm file without executing any movement. The speed of this operation depends on the number of lines of code that must be generated without executing any movement.

After the recalculation, the machine activates an automatic pause, requiring a further press of the ‘Start cycle’ button to start the processing.
It is recommended before starting the cycle to consider the initial positioning of the machine involving all axes simultaneously.
This is necessary because the machine moves from the current position to the point where it starts working, seeking the shortest route, and to do that, all axes move to arrive exactly at that point.

This means that, for example, the Z axis doesn't lower once reached the starting point, but lowers gradually during the path. This could damage the machine or the material if the latter should collide with material in the middle of the path.
So it is possible, on basis of the situation in which oneself finds, to deselect the movement of one or more axes, so as to not cause damages.
To do it is enough to select the buttons present above each axis that from green will become red.

The buttons will turn green automatically once pressed on 'Start Cycle'.

View ISO

If the ISO preview has been enabled, it will be displayed to the right of the 'ISO Program Code' frame, another frame similar to the one shown below:

The ISO preview makes available the following buttons:

	Perspective view Allows to have a 3D representation of the image.
	Orthogonal viewing to XY plane Allows to have a representation of the piece, with respect to the XY plane.
	Orthogonal view to ZX plane Allows to have a representation of the piece, regarding the ZX plane.
	Visual perspective orthogonal to the ZY plane It allows to have a representation of piece, compared to ZY plane.
	Activate or deactivate the preview display Allows to activate/deactivate the preview viewing.

Execution of working

The operator has the possibility to create a list of PGM files by opening the desired files through the dedicated upload function.

Before to start execution, is possible — optionally — to modify order of files in list and to insert any pause between an execution and the other. These pauses allow to manage more flexible process and, if necessary, to interrupt it in safety.

By setting the execution mode to 'Automatic', the 'ISO Test' function is also available, useful to verify the correctness of the selected ISO program before the actual execution.

To start the execution cycle, the operator must press the 'Start Cycle' button. In this way, the first ISO program loaded and displayed in the list will be executed.

The ISO programs can be executed according two operative modes:

The 'Single' mode allows to interrupt the program execution at the end of each ISO file execution. It is necessary to press again the ‘Start Cycle’ button to proceed with the execution of the next file in the list.

The 'Next Automatic' mode allows the execution of ISO files in sequence, without need of manual intervention, until the end of the list.

In both modes, any pause inserted between files allows the operator to interrupt the cycle at any time, guaranteeing thus a continuous control on the execution.
