Status Labels

Status Labels Tutorial

Status labels are created using a QLabel and setting the Object Name. Status labels come in two forms. A single-status-label like Machine Status only contains one piece of information, such as OFF, RUN, etc.

A multiple-status-label like the axis or joint dictionaries have multiple items and displays for all joints. Multiple-status-labels use a number identifier to select the axis, joint, or spindle information wanted.

When creating a status label, set the objectName to the status you want to display

Precision

Labels that return float values default to 3 decimal places for metric and 4 for inch.

To override the default, select the label then click on the Green Plus sign in the Property Editor to add a Dynamic Property and select String. See Dynamic Properties

Set the Property Name to precision:

Set the Value to how many decimal places you want for that status label

For more information about status labels read the LinuxCNC Python Interface Status Attributes

Note

You don’t have to use all the labels; only use the ones you need.

Axis Status

The Axis status contains status items for all 9 axes. Replace the n with the number of the axis. Axis numbers start at 0 and go through 8. Returns a float

Axis Status Labels

axis_n_max_position_limit_lb	axis_n_min_position_limit_lb
axis_n_velocity_lb	axis_n_vel_per_min_lb

Note

The Axis velocity label only reports back jogging speed; use the joint velocity label for linear speed.

Joint Status

The Joint status contains status items for 16 joints. Replace the n with the number of the joint. Joint numbers start at 0 and go through 15

Joint Status Labels

joint_backlash_n_lb	joint_input_n_lb
joint_min_position_limit_n_lb	joint_enabled_n_lb
joint_jointType_n_lb	joint_in_soft_limit_n_lb
joint_fault_n_lb	joint_max_ferror_n_lb
joint_output_n_lb	joint_ferror_current_n_lb
joint_max_hard_limit_n_lb	joint_override_limits_n_lb

joint_max_soft_limit_n_lb	joint_vel_sec_n_lb
joint_vel_min_n_lb	joint_homing_n_lb
joint_min_ferror_n_lb	joint_inpos_n_lb
joint_min_hard_limit_n_lb

Special Labels

Run from line label start_line_lb

Axis machine position labels (no offsets.) Returns a float

Machine Absolute Position Status Labels

actual_lb_x	actual_lb_y	actual_lb_z
actual_lb_a	actual_lb_b	actual_lb_c
actual_lb_u	actual_lb_v	actual_lb_w

Axis position labels including all offsets. Returns a float

DRO Relative Status Labels

dro_lb_x	dro_lb_y	dro_lb_z
dro_lb_a	dro_lb_b	dro_lb_c
dro_lb_u	dro_lb_v	dro_lb_w

Axis Distance to Go labels

Distance to Go Labels

dtg_lb_x	dtg_lb_y	dtg_lb_z
dtg_lb_a	dtg_lb_b	dtg_lb_c
dtg_lb_u	dtg_lb_v	dtg_lb_w

Axis-is-homed labels

Axis Homed Labels

home_lb_0	home_lb_1	home_lb_2
home_lb_3	home_lb_4	home_lb_5
home_lb_6	home_lb_7	home_lb_8

Offsets for the currently active G5x coordinate system. Returns a float

G5x Status Labels

g5x_lb_x	g5x_lb_y	g5x_lb_z
g5x_lb_a	g5x_lb_b	g5x_lb_c
g5x_lb_u	g5x_lb_v	g5x_lb_w

g92_lb_u	g92_lb_v	g92_lb_w

Velocity Labels

Tool velocity using two perpendicular joint velocities.

Name the label two_vel_lb and add two int type Dynamic Properties called joint_0 and joint_1 and set the values to the perpendicular joint numbers you want to calculate. Typically this would be for the X and Y axes.

To select an int type of Dynamic Property, select Other after clicking on the green plus sign

Then select the Property Type of int

The two Dynamic Properties should look like this

Tool velocity using three perpendicular joint velocities.

Name the label three_vel_lb and add three int type Dynamic Properties called joint_0, joint_1 and joint_2 and set the values to the perpendicular joint numbers you want to calculate. Typically this would be for the X, Y and Z axes.

I/O Status

The I/O status contains status items for 64 I/O’s. Replace the n with the number of the I/O. I/O numbers start at 0 and go through 63. Analog I/O returns a float. For example a QLabel with an object name of din_5_lb will show the status of the motion.digital-in-05 HAL pin

I/O Status Labels

HAL Pin	Label Name
motion.analog-in-nn	ain_n_lb
motion.analog-out-nn	aout_n_lb
motion.digital-in-nn	din_n_lb
motion.digital-out-nn	dout_n_lb
