EdgeCAM Editor Guide

EdgeCAM Editor is a Windows-based text editor, provided with EdgeCAM. The Editor provides apowerful set of NC file editing functions as well as standard file editing features.

You can edit one or more files at the same time. These files can be:

NC files.

ASCII format files (for example, EdgeCAM’s PCI macro files, Source files for the EdgeCAMCode Generator).

You can also use NC code editing functions, such as:

Resequencing block numbers and converting from metric to imperial units.

Performing specific comparisons between two files and viewing the differences.

About the Editor Window

Once you open a file within the Editor using the Open (File menu) command, a file isdisplayed in a window that is sizeable and moveable.

The contents of the window can be scrolled horizontally and vertically. Most of the text isdisplayed as black on white. Depending on the control type, special word IDs or key words arehighlighted in red, and remarks within the text are coloured green. The sequence number iscoloured blue (although you can configure the colours as required in the Miscellaneous tab ofthe Options (Settings menu) command).

A typical NC file might look like this in the Editor:

A file can also be split to show several parts of the file at the same time. For details seeSplitting File Windows.

When you activate the command, a dialog appears from which you can select the type of newfile:

Click on OK to display a new window containing the blank file.




NC files.







Opening, Closing and Saving Files

The Open (File menu) command displays a directory dialog. The default file extension isthe last extension used, provided that it is one that the Editor recognises. You can addcustomised file extensions as required.

Use the Browse... button to help you search for a particular file.

You can also select from the last files opened in the Editor: these appear at the bottom of thefile menu, above the Exit option.

The Close (File menu) command removes the currently active document window.

If the file has changed since it was last saved, you are asked if you want to save it.

The Save (File menu) command saves the active file under its original name andlocation.

The Save As... (File menu) command allows you to select a new file name from a directorydialog. The Editor saves the file under this new name.




NC files.







Customised File Extensions

As well as the normal .nc extension used to identify NC code files, you can create your own fileextensions.

The extension is added using a simple setup dialog. Any files opened with the extension will betreated in exactly the same way as .nc files.

The file types are added using the File Types tab dialog of the Options (Settings menu)command:

Any number of file types may be added by typing in the extension, filling in the Name fieldsand clicking on Add/Update.

When you type in a new extension, the Name defaults to the extension plus the word ‘File’.

If the leading ‘.’ is omitted it is automatically inserted. Wild card characters (‘*’ or ‘?’) do notwork.

If you select an existing extension you can modify it. You must click on the Add/Updatebutton to keep the modifications.

Finding Lines or Sequence Numbers

You can use the Goto (Edit menu) command to move straight to a specified line (or sequencenumber as well in NC files).

Note that the number of the current line in a file is shown on the right of the status bar.




NC files.







Changing the Display Font

The Font (Settings menu) command allows you to change the display text font, size andstyle for text and NC files. This command has no effect for .log files.

Some of the available fonts are provided by the selected printer (set using the Print… (Filemenu) command). Other available fonts will depend on other software components previouslyinstalled on the PC.




NC files.







Defining the Format of a Word

The Word Formats tab dialog of the Options (Settings menu) command allows you todefine the format for a word:

This overrides any formatting within the configuration file, or provides information where noconfiguration file is available.

To create a new word, type in the letter address of the required word in the box at the top leftof the dialog. Specify all relevant parameters (which are listed below), and click on the Updatebutton to save the information.

The information in this dialog is used when you select the Format (Edit menu) command.

Letter Description This lists all currently available words.

Letter Address Usually a single upper case letter, but it can be any combination of ASCIIcharacters.

Description – Enter or edit a description for the currently selected word.

Insert – Click on this button to indicate that any changes to the active word should be saved.

Delete – Click on this button to delete the currently active word in the list.

Numerical Precision – Specifies the number of possible digits before and after the decimalpoint for both metric and imperial values.

The sample output allows the user to input a value which is formatted for both imperial andmetric. The two results fields are not editable.




NC files.







Format Control – These check boxes form the format options for the currently selected wordID within the currently active NC file.

Lead Zeros/Blanks – Check the box to force leading zeros/blanks before a value to give a fixednumber of places before the decimal point. For example, if Lead Zeros was selected andBefore (in Numeric Precision) was set to 4, the value 34 would be represented as 0034.

Trail Zeros/Blanks – Check the box to force trailing zeros/blanks after a value to give a fixednumber of places after the decimal point, as determined by the Decimal Places parameter.For example, if this parameter was selected and Decimal Places was set to 4, the value 3.5would be represented as 3.5000. Machines that do not use a decimal separator normally havea fixed number of decimal places.

Suppress Decimal – Check the box to remove the decimal point.

Use ‘,’ instead of ‘.’ – Check the box to replace the decimal point with a comma.

Force ‘.’ on integer – Check the box to add a decimal point to values with no decimal places.

Force ‘.0’ on integers – Check the box to append '.0' to values with no decimal places.

Force ‘±’ on positive numbers – Check the box to add a positive sign in front of positive values.

Right fill with spaces to a total of 5 – Check the box to force the word to be 5 characters longby truncating or right filling.

Right fill with spaces to a total of 10 – Check the box to force the word to be 10 characters longby truncating or right filling.

Do not output 0 after letter address – Check the box to suppress the value if zero.

Output 000.000 as 0 – Check the box to ignore all formatting for a zero value.

Can convert units – Check the box to permit values to be changed by a factor of 25.4 when convertingbetween metric and imperial units.

Resequencing NC Files

The Resequence (Edit menu) command resequences the NC file. The command can also addthe sequence word to NC files that do not already contain it.

The sequence word is set up using the Word Formats tab of the Options (Settings menu)command dialog. See Defining the Format of a Word for details.

You can also set up the parameters for the resequencing using the Resequence tab of theOptions (Settings menu) command dialog. See Specifying Resequence Settings for details.

Once you activate the command, the active NC file is resequenced using the set parameters.You will see the line number (displayed on the right hand side of the file window's status bar)rapidly increment as the resequencing progresses.

The Remove Sequence (Edit menu) command removes any existing NC file sequencing.




NC files.







Specifying Resequence Settings

The Resequence tab of the Options (Settings menu) command allows you to specify thesettings for an NC file Resequence (Edit menu).

Once the Options command is selected, this dialog appears (select the Resequence tab):

Word ID – Specifies the sequence word to use. Note that you can use the Add Sequence(Edit menu) command to add a sequence word to lines if it is not already present.

Start – Specifies the initial number for the first sequence word.

Increment – Specifies the amount by which to increment each sequence word.

For example, if Word ID is set to N, Start = 10 and Increment = 10, the file would beresequenced as:

N10N20N30N40...

Rules – The available combinations of Triggers and Labels that can be used forresequencing.

Trigger – Specify a string to search for embedded subroutine calls.

Label(s) – A list of word IDs which identify letter addresses to be renumbered (for example, N,P, Q, and so on).

Update – Updates a rule.

Delete – Deletes a rule.

If you resequence a file containing embedded subroutines (using the Trigger string), the Editorautomatically updates all corresponding jump references. For example, G71 P120 Q280 U1.0V0.5 F35.0 S2300, where the triggers are the combination of G71 with P and Q. P and Qidentify the block numbers which identify the embedded subroutine. For many controls thiswould be blank.




NC files.







Entering NC File Information

The Properties (File menu) command (only available for NC documents) allows you tospecify the control type, and lists the size and number of lines in the file:

The control type determines the way text colours are displayed for different words, and so on.

The information is appended to the beginning of the file, like this:

If you have checked the Expanded File Information box in the Editor tab of the Options,Settings menu command, the Properties appears like this:

The information is stored in the file in a manner that could cause problems if you attempt toload the file into another editor (or transmit it using another DNC system).




NC files.







Formatting NC Files

Selecting the Format (Edit menu) command displays this dialog:

Reformat – Reformat each line according to the settings in the Word tab of the Options(Settings menu) dialog.

Metric to Imperial or Imperial to Metric – Converts all applicable words using a definedconversion factor (usually 25.4). The function also changes the unit designation (for example,G20 to G21).

The Editor keeps this setting as the new default type of units, until changed again with thiscommand.




NC files.







Changing the Appearance of the NC File

The Editor tab of the Options… (Settings menu) command allows you to configure theappearance of the file on screen and when printed out.

Print Options – This set of buttons controls how the file appears when printed. You mustalready have set the file's Title using the Properties (File menu) command for the title to bedisplayed.

The example below shows a file being displayed in Print Preview mode. Note the date, time andpage number in the page footer:

Auto-save – These checkboxes allow you to choose when the current file is to beautomatically saved:

Before Send to Machine – See Sending an NC File to a Machine.

Before Running Tool – ‘Tools’ are any customised commands in the Tools menu. SeeConfiguring the Tools Menu.




NC files.







File Formatting – These radio buttons let you set Metric or Imperial unit formatting.

Tab Space – This determines the width of a tab in character spaces. For proportional fonts(where not all characters are the same width) this is taken to be the number of averagecharacter widths.

Expanded File Information – Check this box to use the older method of file information. SeeEntering NC File Information.

Colour – This controls the colour of several text features:

Text – Controls the standard text colour.

Comment – Sets the colour of any lines marked as comment lines. The characters marking thebeginning and end of comment lines are defined in the Miscellaneous tab by the CommentFrom and To parameters.

Ignore Line – Sets the colour of any text beginning with an asterisk. This text is not sent to theMachine Tool.

Word ID – Set the colour of all specified Word IDs.




NC files.







Setting Miscellaneous NC Parameters

Select the Miscellaneous tab of the Options (Settings menu) command to display theseparameters:

Configuration File – Specifies an optional task (*.blc file) that is automatically executedwithin the Editor for NC programs nominated for this control. This task converts the NC code ofthe current line into readable text, which is displayed in the Editor’s status bar.

Click on the Browse button to search for a configuration file. This displays configuration fileswith the extension .blc.

Comment From – This parameter defines the start of a comment line in the NC file for thisMachine, which would typically be the ( character.

To – This defines the end of a comment within the NC file for this Machine, and would typicallybe the ) character.

The colour of comment lines can be controlled from the Editor tab. Comment lines are sent tothe machine tool.

Optional Line – This defines the character that appears in front of the sequence number. Thisis typically the / character, and indicates to the Machine that any block of informationpreceded by this character may be ignored if the Machine is in that particular mode.

Set Units – The information entered here is used by the Format (Edit menu) command.

Metric – Indicates the code and value that defines that the machine is to operate in metricmode. For an ISO type control this is typically G21.

Imperial – Indicates the code and value that defines that the machine is to operate in imperialmode. For an ISO type control this is typically G20.

Changing NC Files Using Global Arithmetic

Use the Global Arithmetic (Edit menu) command to make changes to the file using macros.These macros can be created from new or pre-defined.

When you select this command, a dialog appears with a blank window. You can now either typein a macro or load a pre-defined .mlc macro file.

Here is an example of a simple macro:

The macro can change the values of any words identified for the control associated with the file(‘default’ if no control specified).

An example macro is xyz.mlc, shown here:

If you check the Confirm Changes box, when you run the macro you will be asked to confirmeach change the macro makes.

Click on the Run button to activate the macro. When the macro reaches a position in the filewhere a change is required, this dialog is displayed:




NC files.







Confirm – Click on this button to accept this change and continue the macro.

Ignore – Do not make this change but continue running the macro.

Finish – Stops the macro, accepting any changes made so far.

Cancel – Stops the macro and resets any changes made.

Here is a simple command used in a Global Arithmetic macro:

#WORDw

This macro command allows you to specify a variable, generally using a single letter word IDw, such as N for the sequence word or X, Y, Z for co-ordinates and so on.

The Editor changes any line when either the buffer has been modified or a word on the line haschanged. Any word values that are modified are automatically formatted according to thecontrol setup.

Example

#WORDX=#WORDX*2

This sets the new value of the word ‘X’ to ‘2 times the previous value of the word X’.

The expressions used in Global Arithmetic include addition, subtraction, multiplication anddivision.




NC files.







Comparing NC Files

The Compare menu contains commands for comparing the active file with another open file.These are:

File Compare – Compares two files. This may only be selected when you have an activeNC file loaded in the Editor .

Stop Compare – Halts an ongoing comparison. This may only be selected once you haveused File Compare to start a file comparison.

Resynchronise – Restarts comparison at a common point. This may only be selectedonce you have used File Compare to start a file comparison.

See also Changing the Comparison Settings.




NC files.







Comparing Two Files

The File Compare (Compare menu) command identifies the differences between theactive open file and another open file. The comparison can either be a straight text comparisonor the comparison of specific words by value.

Once this is selected, you must choose the other open text window. When you move the cursorover an appropriate file, the cursor shape changes to a crosshair.

The comparison is then carried out, beginning at the current text cursor position in eachwindow.

When a whole line appears to be different, the comparison function attempts to automaticallyresynchronise the comparison.

The result of the comparison is stored in a file called output.log, which is displayed in a newwindow from the beginning of the comparison process.




NC files.







How to compare files

The currently active document should be the first of the two files that you want to compare.

Click on the File Compare (Compare menu) command .1.

The cursor now changes to a crosshair when you move it over another document window:2.

Click on the second, non-active document that you want to compare.3.

The comparison now takes place. A new window appears, displaying the differences betweenthe two files as they are found. This information is also written to a file called Output.log:

The contents of this log file depend on how the comparison was configured in the FileCompare tab of the Options (Settings menu) command.

You are advised when the process is complete:




NC files.







Stopping the Comparison

The Stop Comparison (Compare menu) command halts an ongoing comparisonprocess. This may only be selected once you have used File Compare to start a filecomparison.




NC files.







Resynchronising the Files

The Resynchronise (Compare menu) command restarts the comparison process aftera halt due to finding a difference between the two files. The process restarts at the nextcommon point between the two files.




NC files.







Changing the Comparison Settings

The Options (Settings menu) command allows you to change parameters that the Editoruses when comparing two open files.

Select the File Compare tab to display this dialog box:

Comparison – Select the type of comparison you want to make: Text, Word Value or LineType.

Stop on differences – Mark this box to halt the comparison process and immediately reportthe result.

In this case, a difference in a comparison is reported as follows:

Auto-Resynchronise – Mark this box to automatically resynchronise the comparison after adifference has been identified.

Start at top – Mark this box to always start the comparison from the top of each file.




NC files.







Sending an NC File to a Machine

The Send to Machine(File menu) commandallows you to send thecurrent NC documentdirectly to a Machinetool without having tosave the file and invokethe Machine menu.

The command displaysa sub-menu whichshows all the locallydefined Machines.

When you select a machine from the list, the default transmit task sends the active documentto the machine tool.

The file is normally transmitted beginning from the top of the NC file. However, you can set the

start point of a transmission using the 'bullet' marker (as shown in the above example).

You can set the position of the bullet to the start of the line containing the cursor by pressingthe F2 key or by selecting the Show Send Bullet (View menu) command. As the file is sent,the view of the file scrolls down, with the bullet marker showing the current line being sent.

While the file is being transmitted, the Editor displays this toolbar:




NC files.







PauseTo pause the transmission, click on the Pause button . During apause, you can reposition the bullet as required. When you click thepause button again to resume sending, the next line sent is the oneyou marked with the bullet.

Start/Re-start

To restart the transmission from the beginning of the file (forexample, to include the header), click the Start button .

StopTo cancel the transmission, click on the Stop button .

When the bullet reaches the end of the document, the transmission ends and the toolbardisappears.

There is an Autosave Before Sending to Machine checkbox in the Editor page of Options(Settings menu) to force a save of the document before it is sent to the Machine. This optionis checked by default.




NC files.







Configuring the Tools Menu

The user-configurable Tools menu lets you run other applications and custom Communicationstasks from the Editor. For example:

The Before Running Tool checkbox in the Editor page of the Options (Settings menu)command forces all documents to be saved before any of the tools are run (the default ischecked). ‘Tools’ are any customised commands in the Tools menu.

To configure the menu, use the Customise (Tools menu) command:

The Menu Contents list box displays all the currently displayed options.

Menu Text – the text displayed in the menu for the currently selected item. Place a ‘&’ symbolin front of the character you want to use as a standard Windows hotkey within the menu.

Task Command – the executable command line or the custom Communications task filename. You can select the task (or executable) using the Browse button.

Initial Directory is the current working directory when the option is selected.

The lists beside the Task Command and Initial Directory edit boxes provide a list of variablesthat will be replaced when the option is selected from the menu. These are:




NC files.







File Name includes the extension.

File Path includes the full directory path and the name.

File Title is just the name without the extension.

Control Name is the name given in the file information (the default is <Generic>).

File directory is the full directory to the current document file without the final ‘\’ character.Similarly the CAM and DNC directories are the paths to these two local areas (e.g. c:\edge\camand c:\edge\dnc).

Display Output Screen – Check to open an output screen window for the task. This is onlyapplicable for custom Communications tasks.

Display Task toolbar – Check to display the toolbar. This is only applicable for customCommunications tasks.

Add – Blanks out the edit boxes so that a new option can be added. On completion the newoption is added to the menu. In the example below, 'Calculator' has been added:

Remove – Deletes the currently selected option.

Move Up and Move Down – change the relative position of the currently selected option.




NC files.







Leaving the Editor

To close down the Editor , select Exit (File menu).

If you have any open files that have changed since they were last saved, you are asked if youwant to save them.

If you want to move to another application, you can either minimise the Editor or press ALT +Tab to cycle through the other active Windows applications.
