NAME

       moveoff_gui - a GUI for the moveoff component

SYNOPSIS

       moveoff_gui [--help | -- -h | -?]

       moveoff_gui [options]

DESCRIPTION

       Moveoff_gui  is  a  sample  graphical  user  interface (GUI) for controlling a HAL moveoff
       component to implement HAL-only offsets.  See the  manpage  (man  moveoff)  for  IMPORTANT
       limitations and warnings.

       Supported  configurations  must  use  a  known  kinematics  module  with KINEMATICS_TYPE =
       KINEMATICS_IDENTITY.  The modules currently supported are:
          trivkins

OPTIONS

       --help | -? | -- -h
              Show options and exit

       -mode onpause | always
              onpause: popup GUI to control offsets when program paused
              always:  show GUI to control offsets always
              Default: onpause

       -axes axis-names
              Letters from set of {x y z a b c u v w}
              Examples: -axes x, -axes xyz, -axes xz (no spaces)
              Default: xyz

       -inc incrementvalue
              Specify one increment value per -inc (up to 4)
              Defaults:  0.001 0.01 0.10 1.0

       -size integer
              Overall gui size is based on font size, typically 8 - 20
              Default: 14

       -loc center | +x+y
              Initial location on screen
              Examples: -loc center, -loc +20+100
              Default: center

       -autoresume
              Resume program when move-enable deasserted
              Default: notused

       -delay delay secs
              Delay for autoresume (allow time to restore spindle speed etc) Default: 5

OTHER OPTIONS

       These options are available for special cases:

       -noentry
              Disables creation of entry widgets
              Default: notused

       -no_resume_inhibit
              Disable use of resume-inhibit to controlling gui
              Default: notused

       -no_pause_requirement
              Disable check for halui.program.is-paused
              Default: notused

       -no_cancel_autoresume
              Useful for retracting offsets with simple external controls
              Default: notused

       -no_display
              Use when both external controls and external displays are in use
              Default: notused

NOTES

       LinuxCNC must be running.

       Halui must be loaded, typical INI file setting:
           [HAL]HALUI = halui.

       The moveoff component must be loaded with the name 'mv' as:
           loadrt moveoff names=mv personality=number_of_axes

       If the pin mv.motion-enable is not connected when moveoff_gui is started, controls will be
       provided to enable offsets and set offset values.  If the pin is connected, only a display
       of offsets is shown and control must be made by external HAL connections.

       If a pin named *.resume-inhibit exists and is not connected, it will be set while  offsets
       are applied.  This pin may be provided by the controlling LinuxCNC GUI in use.  Use of the
       pin may be disabled with the option -no_resume_inhibit.

       The -autoresume option uses halui.program.resume to automatically resume program execution
       when  the  move-enable  pin is deactivated and all offsets are removed.  The resume pin is
       not activated until an  additional  interval  (-delay  delay_secs)  elapses.   This  delay
       interval  may  be  useful  for  restarting related equipment (a spindle motor for example)
       While timing the delay, a popup is offered to cancel the automatic program resumption.

USAGE

       The INI file in the configuration directory must provide HALFILEs to  loadrt  the  moveoff
       component,  connect  its  pins, and addf its read and write functions in the proper order.
       These steps can be done at runtime using an existing configuration INI file and specifying
       a system library HALFILE hookup_moveoff.tcl as illustrated below:

       [HAL]
       HALUI = halui
       HALFILE = user_halfile_1
       etc ...
       HALFILE = user_halfile_n
       HALFILE = LIB:hookup_moveoff.tcl

       The  hookup_moveoff.tcl  HAL  file  will  use  INI file settings for the moveoff component
       control pins:

       [OFFSET]
       EPSILON =
       WAYPOINT_SAMPLE_SECS =
       WAYPOINT_THRESHOLD =
       BACKTRACK_ENABLE =

       The hookup_moveoff.tcl will use INI file settings for the moveoff per-axis limits:

       [AXIS_m]
       OFFSET_MAX_VELOCITY =
       OFFSET_MAX_ACCELERATION =
       OFFSET_MAX_LIMIT =
       OFFSET_MIN_LIMIT =

       The moveoff_gui program should be specified in the APPLICATIONS stanza of  the  INI  file,
       for example:

       [APPLICATIONS]
       DELAY = delay_in_secs_to_allow_hal_connections
       APP = moveoff_gui -option1 -option2 ...

       Simulation  configurations  that demonstrate the moveoff_gui and the moveoff component are
       located in:

          configs/sim/axis/moveoff     (axis-ui)
          configs/sim/touchy/ngcgui    (touchy-ui)
