Thanks a lot
Can program refresh be controlled from the classic ladder?

I do recommend not to use halui pins, but the hardware button pins to control that stuff.

Instead of binding this key to a button, is there a way to refresh the g-code file every few seconds while the g-code is not executing? I want to automatically load the g-code file into linuxcnc continuously. The name of the g-code file is always the same and never changes.

Try this:
Save the python code below as 'file-check.py' into a folder named 'python' in your machine config folder and mark as executable.
This user component will create a hal pin 'file-checked.file-changed' and output a pulse if the file is modified:#!/usr/bin/env python3
To load this on startup add this to the [HAL] section of your .ini file:
then add this line to your POSTGUI_HALFILE:

import os

h = hal.component("file-check")
h.newpin("file-changed", hal.HAL_BIT, hal.HAL_OUT)
h.ready()
# create a connection to the status channel
s = linuxcnc.stat()
# this is the file being checked for updates (example looks for 'file.txt' in the config folder)
file_path = 'file.txt'
# length of output puls in milliseconds
pulse_length = 1000
last_modified = os.path.getmtime(file_path)
h['file-changed'] = False

while 1:
s.poll()

if current_modified != last_modified:

h['file-changed'] = True
timer_start = round(time.time()*1000)
last_modified = current_modified
if h['file-changed'] and timer_start + pulse_length <= round(time.time()*1000):
h['file-changed'] = False

Hello,
I think I'm making a mistake somewhere
The file.txt file is in the config folder, but I think it cannot find this file.
./python/file-check.py: 1: import: not found
./python/file-check.py: 2: import: not found
./python/file-check.py: 3: import: not found
./python/file-check.py: 4: import: not found
./python/file-check.py: 6: Syntax error: "(" unexpected
<commandline>:0: waitpid failed ./python/file-check.py file-check
<commandline>:0: ./python/file-check.py exited without becoming ready

Seems likeI lost the hashbang in the first line of the python code in my last post.
I just fixed that, so copy/paste the fixtd python code above and try again.

Note, for the gcode to reload you need to switch to the 'AUTO' mode screen in gmoccapy.
