Enable/disable run button was created by keyson
Hi all, and thank's for all effort to make Linuxcnc better and better.
As the topic say, I would like to disable and enable the run button in Axis on an external signal.
Searched the forums and studied manuals but have not come up with an answer.
I have retrofitted two Denford triac vmc (mod 94) for educational purpose.
They have a 'door' (hatch) that have a sensor (guard contact) that i would like to run trough
a and gate, to make it impossible to run the program if the door is open.
But the jogging would run, so hook it to the enable or e-stop is not an option.
Regards
Kjell

Hi
You can achieve this quite simply by a short hack of Axis
After line 2071 in the master (search for def task_run(*event): )
insert
ie
Then at line 3243 in the master ( search for comp.newpin("notifications-clear-error",hal.HAL_BIT,hal.HAL_IN))
insert
comp.newpin("run-disable",hal.HAL_BIT, hal.HAL_IN)
ie
You will now have a pin called axisui.run-disable
If that is set to TRUE (1) it will not be possible to run a program as the function will return

ie
def task_run(*event):
if comp['run-disable'] : return ## inserted line
if run_warn(): return
global program_start_line, program_start_line_last
program_start_line_last = program_start_line;

c.auto(linuxcnc.AUTO_RUN, program_start_line)
program_start_line = 0
t.tag_remove("ignored", "0.0", "end")
o.set_highlight_line(None)
Then at line 3243 in the master ( search for comp.newpin("notifications-clear-error",hal.HAL_BIT,hal.HAL_IN))
insert
comp.newpin("run-disable",hal.HAL_BIT, hal.HAL_IN)
ie
if hal_present == 1 :
comp = hal.component("axisui")
comp.newpin("jog.x", hal.HAL_BIT, hal.HAL_OUT)
comp.newpin("jog.y", hal.HAL_BIT, hal.HAL_OUT)
comp.newpin("jog.z", hal.HAL_BIT, hal.HAL_OUT)
comp.newpin("jog.a", hal.HAL_BIT, hal.HAL_OUT)

comp.newpin("notifications-clear-error",hal.HAL_BIT,hal.HAL_IN)
comp.newpin("run-disable",hal.HAL_BIT, hal.HAL_IN) ## inserted line
vars.has_ladder.set(hal.component_exists('classicladder_rt'))
You will now have a pin called axisui.run-disable
If that is set to TRUE (1) it will not be possible to run a program as the function will return
