Issue with running python script

seanres · January 20, 2022, 2:39am

What is the problem?

I am trying to create a control button that runs a python script located on my raspberry pi 4 using GCODE System Commands, but I am unable to get the script to run from the button. I also am unsure of how to properly display the terminal output.

What did you already try to solve it?

I have tried rewriting the pathing and taken a look at similar topics, but I cannot get the button to function properly. I also am unaware of how to format the output properly based on the information given by the config.yaml information page.

Does the gcode command work to run the python script from the terminal tab and that part is working?

jneilliii · January 20, 2022, 2:53am

also, does gcode system commands allow up to 801 on it's numbering? I think maybe it should be OCTO01?

I am unable to type into the terminal, I am currently running the octopi disconnected from the printer as I do not have access to it due to covid restrictions. I am trying to build a plugin that will output sensor data connected to the pi so I have been working it it separate from the printer in the meantime. I will attempt to connect it to a printer in a few hours and see if that resolves the issue.

You can enable the virtual printer in settings and have a fake printer connected to test with...

Thank you, I was unaware of this. This resolved the issue I was having regarding not being able to press the button, but I am now getting an error within the terminal when the command is called.

seanres · January 20, 2022, 9:06pm

This is my current command definition, I believe it is pathed correctly as if I type this command within the terminal on remote desktop I get a terminal readout that I would expect but it is not functioning and returning that error.

jneilliii · January 20, 2022, 9:25pm

sometime you have to put the interpreter for the file at the top and chmod +x it to make it executable maybe? so something like #!/usr/bin/python3 as the first line of your py file. or are you using a sh script? The important part that the command is configured with the full path to the file as well in the plugin's settings.

seanres · January 21, 2022, 1:26am

I added the suggested line to the code, added the file to chmod +x, but am still getting the same error. The command is shown below, I am trying to run a .py file.

jneilliii · January 21, 2022, 1:52am

That is probably the issue. I don't think you can sudo with the plugin unless you add a sudoers rule to the OS, but @kantlivelong would have to confirm. With adding those previous bits and making it executable you shouldn't need the python3 command at all I don't think. Does the python file require root access to properly run?

seanres · January 21, 2022, 2:05am

It does not need the root, removing the python3 command does not solve the issue. I am still receiving the same error unfortunately.

kantlivelong · January 21, 2022, 12:40pm

Maybe this will help.

Trouble Gertting Plugin To Execute

question

#### What were you doing? I am using this plugin to execute two python script…s through shell scripts, which are designed to use a servo through an Adafruit Servohat to deploy and retract a brass brush over the print bed to clean the nozzle before each print. This was working on a previous printer, but can not seem to get it to function moved over here. Note: I have rebuilt my Octopi onto an 8 GB Pi 4B+, it was functional on the Pi 3 B, but began having problems (not related to this plugin) so moved it up to the faster processor/more memory. I have also gone through the entire community forum and tried every permutation fix even close to my problem with no success. ------------------------------------------------------------------------------ OctoPrint version : 1.7.2 OctoPi version : 0.18.0 ------------------------------------------------------------------------------ I have validated the validity of both the .sh files and their respective .py files by running them successfully from the command line after ssh'ing into the pi. /home/pi/deploy.py import time from adafruit_servokit import ServoKit kit = ServoKit(channels=16) kit.servo[0].angle = 110 /home/pi/retract.py import time time.sleep(25) # delay retract 25 seconds from adafruit_servokit import ServoKit kit = ServoKit(channels=16) kit.servo[0].angle = 0 /home/pi/deploy.sh #!/bin/bash sudo python3 /home/pi/deploy.py /home/pi/retract.sh #!/bin/bash sudo python3 /home/pi/retract.py OCTO Command Lines OCO10 /home/pi/deploy.sh OCTO20 /home/pi/retract.sh NOTE: sudoers file aliases ezpi (user logged into octoprint with) to %admin, root #### What did you expect to happen? After the extruder reset to the wipe position (back left corner of the bed) and the bed dropped 10mm to clear the brush, I expected the brush to deploy and then after a 24 second time delay, to then retract before it went on to auto-level and print. #### What happened instead? Extruder went to wipe position, went through wipe motions and then on to auto-level pre-print, brush did not deploy/retract. #### Version of OctoPrint-GCodeSystemCommands 1.0.1 #### Operating System running OctoPrint Pi Raspbian - 5.1.63-V71+ #### Printer model & used firmware incl. version Latest Ender 5 Plus, Firmware as shipped two months ago. #### Link to octoprint.log with octoprnt.plugins.gcodesystemcommands set to DEBUG Forgive me, I am unsure how to link to my octoprint.log file, or how to put the plugin into debug mode. I have pasted ONLY the operative lines from my log here: 2021-12-05 10:31:13,506 - werkzeug - INFO - 127.0.0.1 - - [05/Dec/2021 10:31:13] "GET /?action=snapshot HTTP/1.1" 200 - 2021-12-05 10:31:18,518 - octoprint.plugins.detailedprogress - INFO - Message: ETA 12/05 10.47AM 2021-12-05 10:31:18,907 - octoprint.plugins.gcodesystemcommands - INFO - Executing command ID: 10 2021-12-05 10:31:18,991 - octoprint.plugins.gcodesystemcommands - INFO - Command ID 10 returned: 1 2021-12-05 10:31:19,063 - octoprint.plugins.gcodesystemcommands - INFO - Executing command ID: 20 2021-12-05 10:31:19,138 - octoprint.plugins.gcodesystemcommands - INFO - Command ID 20 returned: 1 2021-12-05 10:31:19,206 - werkzeug - INFO - 127.0.0.1 - - [05/Dec/2021 10:31:19] "GET /?action=snapshot HTTP/1.1" 200 - 2021-12-05 10:31:19,703 - octoprint.plugins.octoeverywhere - INFO - NotificationsHandler successfully sent 'progress'; ETA: 911 2021-12-05 10:31:24,104 - werkzeug - INFO - 127.0.0.1 - - [05/Dec/2021 10:31:24] "GET /?action=snapshot HTTP/1.1" 200 - 2021-12-05 10:31:28,520 - octoprint.plugins.detailedprogress - INFO - Message: Good accuracy 2021-12-05 10:31:34,347 - werkzeug - INFO - 127.0.0.1 - - [05/Dec/2021 10:31:34] "GET /?action=snapshot HTTP/1.1" 200 - 2021-12-05 10:31:38,523 - octoprint.plugins.detailedprogress - INFO - Message: 7.01% complete 2021-12-05 10:31:41,767 - octoprint.util.comm - INFO - Cancelling job on behalf of user ezpi

I've looked through that thread and recreated the test files you gave, and I am still getting an error from the octoprint terminal. I've used the chmod +x test.sh command, but running sh test.sh does not return any output or error, I am unsure what I am doing wrong.

seanres · January 25, 2022, 12:50am

I am at my wits end, I have all files running properly through the terminal from remote desktop, but I am returning an error instead of printing from the terminal. My programs are:

ADXLrun.sh

#!/bin/bash
python3 /home/pi/ADXLtest2.py

ADXLtest2.py

import time
import board
import busio
import adafruit_adxl34x


print("Started!")

i2c = busio.I2C(board.SCL, board.SDA)
accelerometer = adafruit_adxl34x.ADXL345(i2c)
accelerometer.enable_freefall_detection(threshold=10, time=25)
accelerometer.enable_motion_detection(threshold=18)
accelerometer.enable_tap_detection(tap_count=1, threshold=20, duration=50, latency=20, window=255)

while True:
    print("%f %f %f"%accelerometer.acceleration)
    print("Dropped: %s"%accelerometer.events["freefall"])
    print("Tapped: %s"%accelerometer.events['tap'])
    print("Motion detected: %s"%accelerometer.events['motion'])
    time.sleep(0.5)

As I see, in your last post you mention that you are trying to use an ADXL345.
AFAIK, only Klipper uses this device.

You may ask that board there too:

Charlie_Powell · January 25, 2022, 11:52am

Shot in the dark, but where is the adafruit_adxl34x library installed?

You could capture the full output of the python script by modifying your first script to look like this:

#!/bin/bash
python3 /home/pi/ADXLtest2.py >> /home/pi/adxltest.log

That might help to diagnose the issue?

Charlie_Powell · January 25, 2022, 11:54am

Also, if you enable debug logging for the plugin, it should log the complete output of the command which might also be helpful.

If you go through the ticket I previously linked it explains how to determine the import issue you are facing. It even has the solution.

Charlie_Powell · January 26, 2022, 7:55am

This is suggesting the wrong path is configured for the script? It is saying /home/pi/test.sh, above you wrote the file name as ADXLrun.sh. so then the error below is saying it can't find that file.
