Q- We are evaluating editNC so we are still running under the 15 day evaluation. How can we test the floating license capability.

A - Floating licenses are not available in evaluation mode. We can provide (through your dealer) a temporary full license for test purposes.


Q- We are upgrading from an older release to a newer release. How can we transfer the existing DNC configuration to the new release?

A - The new release (assuming it is Release 10 or 11) will automatically read the older DNC information, assuming it is being installed on the same computer. This will be done only the first time the new release is run. Release 10 will copy data from release 9, and release 11 will copy from either release 10 or 9.


Q - We need to copy our DNC configuration to additional computers. Where is this information stored?

A - As of editNC R10 it’s saved in a file called “editNC10dnc.Ini” located in the user’s application folder. Release 11’s information is stored in “editNC11dnc.ini” One way to copy it is to use Windows notepad (or even editNC itself).  Do the following…


On the sending computer:


1) Start notepad.

2) Click File-Open and key in  %appdata%\editnc\editnc10dnc.ini   - This will read the file into notepad.

3) Save the file and then somehow get that file to the new computer.


On the new computer:


1) Start notepad and read the file created earlier

2) Click File-Save As and key in   %appdata%\editnc\editnc10dnc.ini   - This will save the parameters. You may need to confirm overwriting an old file.


The DNC parameters should now be identical on both computers. Note that any existing DNC entries will be lost..


To move DNC configuration information from release 10 to Release 11, read the release 10 file into notepad and save as above but use “editNC11dnc.Ini” as a filename.


Q - Some of the characters in the editor are gibberish. For example, tabs should be shown by an arrow but some strange boxes appear instead. Some characters are only partially shown.

Some fonts are just not suitable for use with this application. Also, some very large fonts exhibit this behavior. Try other fonts until you find one that works well.


Q - What conversions are supported by Action-Convert?

A - Various CNC program formats are included


Supported for input and output:



Supported for output only:



Some conversions will require manual completion using the editor, for example where canned cycles do not have a direct match in the target format.


Q - The Conversion function appears similar in function to a postprocessor. Why are there not more options to "flavor" the output?

A - EditNC is a CNC program editor, not a postprocessor. It is designed to handle a wide variety of program formats, unlike a postprocessor which typically deals with a single machine tool / controller family. The conversion function is intended to assist in cases where a suitable postprocessor is not available but there is a need to change an existing CNC program to some other format, for example to produce a program for one-time use on a machine not ordinarily used for that program.


Q - Does editNC support DXF files?

The Conversion function will create DXF output.


Support is included as follows:


G0 These will not appear in the DXF file


G1 Will appear as lines in DXF


G2/G3 Will appears as arcs in DXF


G17-19 Will be handled


G73-76 Will create points at Z depth


G81-89 Will create points at Z depth


G90/G91 Will be handled


No other commands are currently supported.


Q - I want to know what CNC program block caused a particular move in the backplot display. How can I find it?

A - The easiest was is to hold the Shift key down and click on the move in the backplot. This will get you to the block. (In some cases, the backplotter won't be able to locate the block precisely, but it will indicate the applicable area in the program. This is most likely to happen right before or after a tool change).


Q - Can I convert NC programs from inch units to metric?

A – You can use the Global-Adjust dialog to multiply the appropriate address words by 25.4. This usually takes care of most of the work, but obviously tool sizes are not considered.


Q - How are block delete characters (/) handled during resequencing?

A – The editor attempts to leave them where they were. They will be placed immediately before or after the sequence number depending on where they were before resequencing.


Q - A file is shown as "Read-only" but it isn't read only on disk. What happened?

A – The editor views files as read-only in four cases


1. The file (Windows) attributes show it as read-only


2. Multiple copies of the same file are open at once in the same editor


3. “Prohibit multiple user write access” is checked and some other user has the file open in read-write mode.


Q: What is the maximum file size that can be edited?

A: This depends on the amount of memory available. The editor is designed to handle large files while providing good performance. We regularly text with files up to about 40 megabytes (~ 2,500,000 blocks).

Q - What is a null character and why do I care?

A – A character with all bits off. They are sometimes used for punched tape leaders and a few other functions. There is no graphical representation for a null character in Windows so the editor lets the user specify one (Options-Editor-Characters). A seldom used special character such as ~, ^, ` or something over decimal 127 should be used.


Q - I want to do something to most of, but not all of, a large program. What's the best way to select "most of" a program?

A – Put the text cursor at the start, hold the shift key down, and locate the end of the desired area with the text cursor and click there. The text between the two will be selected. If a single tool is used for all blocks you want to select, you can use “Select Tool Range” under the Edit menu.


Q – I'm calling the editor from another program and passing a filename in the command line. Sometimes, the editor produces an error message saying it can't find the file. I can read this file with no problems using File-Open in the editor. What's going on?

A – If a command line includes a file name with spaces, it must be "quoted" per Windows conventions. For example, a command line of editNC.exe cncprog 1.nc will fail but editNC.exe "cncprog 1.nc" will work. Calling programs should simply quote all filenames.

 

Q - I searched for "G1X15.0Z13.25" using Find/Replace. The editor finds a block but the Replace buttons are greyed out. Why?

A - The "Ignore numeric format differences" checkbox  is probably checked. This tells the editor to find blocks containing the G,X, and Z words specified, even if they contain other address words. For example, it would find "G1X15.0Y3.0Z13.25F12.0" in this case. Replacing text in this case would be risky because the editor has no way of knowing if the Y and F values should be removed or retained. For cases like this, uncheck the "Ignore numeric format differences" box.
