plotter graphically draws the 3-axis machine movements in an NC g-code
file, AKA a "tape" file. The command line syntax is:
[.exe] is optional.
plotter window displays the tape file content and the plot of all
tools. The current block being plotted is highlighted at the
vertical center of the window. In addition a "digital readout"
shows the current absolute coordinates of the X, Y, and Z axes,
the current tool number, and the estimated tool cycle time (see note
1). A, B and C rotational axes are also displayed in degrees if
the tape contains them.
Note 1: Tool cycle time is
calculated via the commanded tool feed rates and distances traveled.
For lathes running in constant spindle speed mode inaccuracies in
cycle time will occur for all facing operations (i.e. X-axis movements)
where the spindle speeds up and down and when feed rates in units per
revolution are used. In those cases the RPM of the spindle at the
start of the cut is used which will result in longer or shorter actual
cycle times for that movement.
Note 2: Effort has been
taken to ensure that the plotter is as controller generic as possible.
That being said there is no doubt that the plotter is closely
matched to the tape files generated by my postprocessor.
3: The plotter can plot tape files that contain subprograms.
Tape files must contain an "O" block to designate the beginning
of the main program whether or not they contain any subprograms.
Refer to the SEQNO postprocessor command to determine how to
automatically generate an "O" block.
Note 4: All tape
files must terminate the main program with either an M02 or M30.
Refer to the postprocessor commands "REWIND" and "END" for more
information on how to generate these m-codes.
G: Show/hide the tape source lines, i.e. the g-code file.
Home/End: Go to the beginning/end of the tape file.
Single step forward through the tape. Use Shift-Spacebar to
single step backward. Hold down the spacebar to rapidly single
step forward or back.
Enter: Plot forward up to the next M00/M01 or the end of the file.
PageUP/PageDown: Plot forward/backward one full screen of the tape file.
Keypad +/-: Zoom in/out. The center of the plot's extents is centered in the window.
Up/Down Arrow: Rotate the plot about the X-axis. Use Ctrl-Up/Down to rotate about the Y-axis.
Left/Right Arrow: Rotate the plot about the Z-axis.
Keys 1-9: Plot only the tool corresponding to the given number,
limited to tool numbers 1 through 9.
In addition only the blocks for that tool number are shown.
Zero (0) restores the plot of all tools. For tool numbers
greater than 9 use the right-hand mouse button (see below).
Button: Click and release to place the point under the mouse
cursor in the center of the window. Click and hold to drag the
Right Button: Click and release to display a 2-part
pop-up menu. The top portion lets you select commonly used angles
of view. The lower portion displays the list of tool numbers from
which you can choose to plot.
Scroll Wheel: Zoom in/out about the point under the mouse cursor.
