Version 1.51 of the CNC10 Linux-based control software saw the introduction
of a new default text editor, called
NEdit. Overall it is a
vast improvement over the previous editor. There are, however, a few
differences and a couple idiosyncrasies to get used to.
Pressing ESC will no longer get you out of the editor. Therefore the one command you need to know is:
If you have made any changes, you will be prompted whether you want to save them before quitting. Press Y or N as desired.
Alternately, you can save the file first with:
NEdit is a menu-based editor, similar to Windows Notepad (but much more
capable). All commands are available on drop-down menus. You can get
into the menus with a mouse, if you have one connected, or by using
Alt-key shortcuts as in Windows. For example, Alt-F will drop down the
File menu; Alt-E will drop down the Edit menu; etc..
You can also activate the menus by pressing F10, then using arrow keys to navigate the menus.
The most common and useful commands have Ctrl-key shortcuts. As you browse through the drop-down menus, you will see the Ctrl-key shortcuts displayed next to their commands.
If you use the Open or Save As commands,
NEdit will display
a dialog box and prompt for a file name to load or save. It will show
the name of the current directory, and give you the opportunity to change
directories if needed.
NEdit, however, is a native Linux program, not written by
Centroid. It will therefore show native Linux directories, without
translating into the simulated DOS/Windows format used in the Centroid
software. The "C:" drive will appear as
Most of your CNC G code files will be in
/cncroot/c/cnc10t/ncfiles on Lathe controls).
This is the same location as "c:\cnc10\ncfiles" or "c:\cnc10t\ncfiles" in
the Centroid software menus.
You may sometimes find that the Alt- and Ctrl-key shortcuts will stop working: Ctrl-key shortcuts will just insert strange sequences in your file (e.g. you press Ctrl-S to quit and NEdit inserts "<dc3>" instead); Alt-key shortcuts will insert the unmodified character (e.g. you press Alt-F for the file menu and NEdit inserts "f" instead).
Centroid and other online references will tell you that the keyboard shortcuts will not work unless CAPS LOCK and NUM LOCK are both OFF. This may be true, so try turning off CAPS LOCK and NUM LOCK first, if either is on.
However, it appears there is something else going on, as the Alt- and Ctrl-key shortcuts can also stop working, seemingly at random, even without CAPS LOCK or NUM LOCK.
The most reliable solution is to plug in a mouse (a PS/2 type mouse if you have CNC10 software earlier than v2.60; either a PS/2 mouse or a USB mouse with CNC10 version 2.60 and later). Then you can simply click on the File menu, Save option, Quit option, etc..
Lacking a mouse, if you have a "Windows" keyboard plugged in, try pressing the "menu" key on your keyboard (usually to the right of the space bar). Then press ESC to dismiss the resulting menu. In several cases I have found that this sequence restores correct operation of the Alt- and Ctrl-key shortcuts.
If that is not an option, try pressing F10 to activate the menu bar, then use arrow keys to navigate to Save and/or Quit. If that doesn't work, try using Alt-Tab several times to switch away from the editor and back. Double-check that CAPS LOCK is off.
In some circumstances, keyboard focus will return to the CNC10 control program, even though the editor window is still on the screen. This will cause you to get gray-and-yellow "Invalid Key" messages in the center of the screen as you try to type. To fix this, press Alt-Tab a couple times to switch tasks to CNC10 then back to the editor.
Sometimes when you press Ctrl-F for Find, Ctrl-O for Open, or another command that brings up a floating dialog box, you will find that keyboard focus stays in the edit window instead of shifting to the dialog box.
You can tell this has happened because the blinking cursor will still be in your text: the cursor in the Find box or other dialog box will not be blinking. In this case too, you can get the focus into the dialog box where it belongs by using Alt-Tab multiple times, to jump to the CNC10 control software, then back to NEdit.
Much, much more information can be found at NEdit.org.
The default installation provides a nice large editor window on a 1024x768 SVGA display (such as the 15" screens on post-2001 M400 controls and most M39 controls). Unfortunately, on older M400 controls with 9.4" or 10.4" LCD displays, much of the editor window is off the screen.
To change the
NEdit window size to fit one of these 640x480
If your monitor is getting old and blurry, you may find the default
font hard to read. You can tell
NEdit to use a larger
font, at the expense of a little less information on the screen.
To change the default font from size 12 to size 20:
With the larger font, you won't be able to fit as many rows and columns on the screen. Follow the previous procedure to change your default window size to something that fits on the screen: perhaps 32 X 90 on a high resolution screen, or 22 X 60 on a low resolution screen.
