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.

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 axisnames

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 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 halfile 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 ...
