Enable PWM output

Hello, I've been trying to control a LED-Strip with your plugin and it doesn't seem to be working. I have communication with the Arduino but it doesn't seem to receive or the Raspberry to send anything. Does it work or is it still a work in progress?

I'd be happy to help with the Arudino code but I unfortunately know very little about coding for the RPi.

Thanks for the very useful plugin!

Hi, your plugin is awesome, but missing one thing. Is it possible to implement I2C 1604 or 2004 LCD and display temperatures and status of the enclosure? I'm thinking about LCD next to hardware buttons in one case as enclosure controller.
Thanks

Would love to be able to see the current status of an output. Right now you can't tell if an output is on or off.

Absolutely love this plugin, so thanks. Looking forward to next version. Sounds like some great additions!

Hi,

I'm actually designing a blob detection ( https://github.com/ChrisP-Git/BlobDetector ) that detects if the print get unstuck from the bed and stick to the nozzle, which will create a plastic blob that can detroy extruder wiring.

The thing is based on a laser barrier managed by an arduino that will trigger a digital port in case of obstruction. In this case, the print should be stopped. It's different from end of filament detection where the print should be paused.

What would be perfect would be an additionnal action with specific GPIO port.

Would that be possible, or even make sense to you ?

Under Temperature Sensor configuration, within Sensor Type, there is a link to this github page for information about sensor libraries. The URL is incorrect, and the browser treats it as a relative rather than static link. I think it needs https:// in the URL.

I have attached and read temperature from my 2302 fine from the command line but the Octoprint interface shows no data.

I'm guessing this is because when I try and add the executable flag to the python scripts I get a file not found error, checking manually over SSH the plugins folder is empty... The plugin shows up in the web interface fine.

Im guessing this is because i used the prebuilt Octopi image? Can you help please!

I have a led connected to GPIO17.
Every time I reboot octoprint I need to toggle the "Use Board Pin #", save it and toggle it again before the GPIO works. After the toggle everything works as expected until a reboot.

Me again. I'm getting failed to read errors, I use a dht11 on pin 4 (or 7 however you look at it).

I enabled debug and attaching relevent bits:

2017-03-24 01:57:36,623 - octoprint.plugins.enclosure - INFO - DEBUG -> Reading temperature stdout: <open file '<fdopen>', mode 'rb' at 0x6a0aae38> 2017-03-24 01:57:36,625 - octoprint.plugins.enclosure - INFO - Failed to read Temperature 2017-03-24 01:57:36,681 - octoprint.plugins.enclosure - INFO - DEBUG -> Reading humidity stdout: <open file '<fdopen>', mode 'rb' at 0x6a0aaee8> 2017-03-24 01:57:36,683 - octoprint.plugins.enclosure - INFO - Failed to read Humidity

Let me know anything else you need to identify the conflict.

I have this crazy idea to set the enclosure temperatur depending on the filament type im using.
And not simple switch the fan on/off but using PWM with a PID control loop. (Dont have a heater, too scary)

I build a fan controller with an Arduino where i can set the temp and the fan speeds up if the temp gets too high. But it is missing the link to Octoprint.

I am ok with mixing examples for the arduino and make them run with a good looking code, but Linux on the Pi is something i have trouble with.

As a first step setting the temp in Octoprint would be great.

I checked the sensor by running through the directions at: (https://learn.adafruit.com/adafruits-raspberry-pi-lesson-11-ds18b20-temperature-sensing?view=all). The sensor reads fine using those directions.

This plugin is great. I use it all the time and it's nice to know my printer will shut down after I have gone to bed! ;-)

I understand how auto shutdown works, but there is a pretty common scenario where it does something unexpected. Say, you have auto shutdown set for 500 seconds after print completes. These steps will cause a problem:

1. Start a print
2. Get a bad first layer
3. Cancel print job
4. Correct problem
5. Restart print job
6. Job is running fine until 500 seconds after the first cancel of print job in step 3

If you are using it to turn the PSU on and off (which is a fairly common set up), your second print job will fail because the shut down. You can manually start up the PSU again, but by that time the print has been messed up and things are out of sync.

Is it possible to cancel the outstanding shut down timers when a new job is started?

The fan and other io being able to react to temperature readings, gpio triggers, web post\get etc.

Hi,
It would be nice to have a default temperature value in settings. It starts heating automatically when octoprint printing starts.

Just got a DHT11 connected and am testing that out. Have a suggestion and issues.

1. Please show temperature type indicator (F/C) next to temperature readout

2. The temperature shown sometimes has massive precision. I saw a temp a minute ago that showed something like (69.8000000000). Couldn't see beyond the last 0, as it overfilled the table cell.

3. Temperature readout is all over the place sometimes. Right now it's about 68 degrees, and usually shows 68, but sometimes shows completely random numbers like 154.4 and 300+. I assume this is a return from the DHT library, but I'm unsure how I could test this further at a command prompt.

After updating to Version 2.4, the GUI on the web interface is no longer visible. See the attached picture.

Could you add support for an LM35 temp sensor?

I have one wired up already thinking it might work, but unlike a DS18B20 it creates a 00-xxxxxxx directory and not a 28-xxxxxxx

Thanks,

D.

Hi, I love your plugin - and I just asked myself if it's possible to add/configure an email notification as soon as the filament sensor got activated? Thank you!

When the printer is disconnected the buttons grey out and can't be clicked. being able to use the gpios at all times would be great if possible

Thanks for the plugin. It'll be just what I need. For now, I'm just trying to control the PC power supply that supplies power to my printer. I have configured GPIO 17 (board pin 11) as an output. However, using the button, for that GPIO, in your interface does not change the output voltage. So I must be doing something wrong.

To check my sanity, I went into Python and used the RPi.GPIO module to control the pin and that works. If I configure GPIO.BCM, it's pin 17 that works. If I configure GPIO.BOARD, it's pin 11 that works.

Can you figure out what I'm doing wrong?

I have version 3.51 of the plugin.

I'm using a filament sensor and everything works well when I use "pause printer".
But there's a problem: The nozzle stays hot, the printer stops directly at the position where it got the signal. Means: Directly at the printed part.

My expectation for "pause printer" would have been:

• printer stops x/y motions
• print head will be raised (10-20mm would be enough)
• printer stops heating (because if I'm not at home, it shouldn't stay heated unattended)
• then I could manually change the filament (after manual preheating)
• and after loading the new filament I click on "continue" in Octoprint and the print head lowers down to the last print position - and continues printing

Currently this is not working for me this way:

• either it stops and stays heated (possibly for hours) ["pause printer"] OR
• or it just ignores the filament sensor completely ["change filament"]

Is there anything I can do to achieve the behaviour I described?

Thank you!

when I check off temp control there's a small drop effect of maybe 50px but nothing shows up about choosing heating or cooling etc.

Hi,
Filament sensor won't work for me. I see "RuntimeError: Failed to add edge detection" in logs.
I think it is about permissions. I added pi user to gpio group and my system is up to date.

When adding an input for GPIO control, the event trigger field is set to "fall" even if the "rise" option is selected.

Would it also be possible to add functionality to shut off the heater/temperature control from the GPIO input? I've added a smoke detector to my enclosure and would like to be able to shut off both the printer as well as the heater if smoke is detected.

(Also really minor but it looks like there's a typo in the plugin url in setup.py, so the octoprint plugin manager does not redirect to this github page properly.)

Why don't you consider the integration with "OctoPrint-telegram" plugin integration adding the possibility to switch relay, see temperature,... from telegram bot? And what about adding the switch button on the navbar? Beautiful plugin, anyway!

Hi,

Awesome plugin to start with. I was planning something along these lines when yours was released - saved me a whole bunch of work.

My current problem is that I'm using temperature control to control a small fan. Set up to turn on a relay at x degrees, it works perfectly. However, when the temperature drops below x degrees again, the relay does not turn off.

Am I doing something wrong?
Is this the way it's designed?

Cheers,
Mike.

This may not be an issue in the next release already but I have two IO's set for fans. They are set to turn off 3 minutes after a print. the issue I'm seeing is that if the print ends and I start another before the shutdown delay has passed then they will still shutdown during that next print. since the IO start sequence has already fired at that point, they will remain off through whole operation.

I hope that's clear. ask any questions you need

When the temperature control isn't configured, you get the following error message:

Hi, It's me again, is it possible, in the next releases, to add toggle buttons for relay on the navbar (near the settings icon for example) like the "Octoprin PSU control" plugin? Maybe giving the possibility to choose which toggle add to the navbar and which not. Thank you!!

Having the ability to stop a print in case of loss of filament for a dualstruder setup would be amazing.

Adafruit already has a python lib for BME280.
https://github.com/adafruit/Adafruit_Python_BME280

Happy to test this out when you're ready.

Hi,
This plugin looks very nice and it seems like it extends OctoPrint with many features I could use. One challenge for me, is that I prefer to use MQTT driven external devices, rather than connecting via GPIO's on Raspberry. Is it possible to modify this to use MQTT commands instead?

Setting up input
Event type: printer
Printer action drop down: Says "Hise", should be "Rise"

This is obviously an enhancement request.

I currently use a plugin that notifies me when prints start/stop etc via telegram messenger. I'd love to get notifications (for example filament run out, smoke sensors etc) in the same way.

Can plugins in OctoPrint talk to each other? Obviously, with the multitude of different plugins, it'd be hard to cater for them all.

Just a thought though.

Cheers,
Mike.

windows 10, firefox latest stable, no ad block etc. octoprint is on rpi3.

Add output works fine. The first time I hit add input it closed the settings menu. every time since it just does nothing

Is there any possibility to change the sensor type to DS18B20? So DHT sensors are sometimes hard to get in some countries. Would be nice if there is an easy way to change this. Also would be interesting adding a second or some more fans.

Thanks in advance
Regards
Dominik

If I make any changes to enclosure config, outputs always turn off rather than staying in their previous state.

Reproduce:

1. Create output and turn output on/high
2. Change any enclosure config item (does not have to be related to output)
3. Save config. Output is now in low/off state.

In my case, it turns off the printer.

Additionally, when octoprint server is restarted, outputs return to low/off state.

Bet you saw this coming. I need one more io at least lol. I ended up putting hotend, ramps, and an eclosure fan on relays, plus the lights and I'm maxed out. I holding out hope for temp triggers some point down the line so I am installing the fire supression soleniod setup now since I have the parts ready.

I'm getting an error in my logs that says "octoprint.plugins.enclosure - INFO - Failed to convert to float" when trying to read the temperature from a DS18B20 sensor. If I run the scrip manually, I get the proper temperature:

pi@octopi:~/.octoprint/plugins/OctoPrint-Enclosure/extras $ sudo ~/.octoprint/plugins/OctoPrint-Enclosure/extras/GetTemperature1820.py 1820
20.3

It seems sTemp is empty after the Popen to the get temperature script...

Anything I'm missing?

I have no idea if it's possible but adding a line to the temperature chart for enclosure temperature would be so helpful to me. I'm trying to see if my enclosure heating system is effective and well balanced but that's impossible without some kind of record of temperatures over time.

I already use OctoPrint-TempsGraph to improve my chart, so maybe there's a way to connect to that?

Thanks for the plug-in

I did something similar using Arduino, but am fairly new to the raspberry pi and Octoprint.

Is it possible to add two additional features?

• gap control - allow the temperature to drift by a user specified gap above and below the set temperature. This could potentially prevent short runs on the heating element

• allow the user to specify a maximum temperature and then either shutdown the heating element (and not use it again) or assume a worst case scenario and completely shutdown the printer

Thanks again

Hello,

Could the temperature and humidity be shown like this:

Maybe the possibility to set the names for the two values yourself (to make it fit)? Like T: 22C H: 35%
The "Navbar Temperature Plugin" shows the Pi temperature.

After my A8 going up in smoke and nearly burning my house down, I want to add a safety system that with the help of my Pi3 and a few detectors I would get some warning,
I don't know how to do it myself but I think others would be interested too.

This is in reference to OctoPrint-PSUControl#19

It appears that this plugin uses GPIO.cleanup() with no arguments which can break GPIO for other OctoPrint plugins. Instead configured GPIO pins should be tracked locally and individually cleaned up when necessary.

Is it possible to add start/stop time support based on actual time. For example, I have my lights turn on at start of print but would like them to go off at 10pm.

Thank you and keep up the great work!

I setup five gpio outputs and went tot test them. if i toggle them for a bit at some point the printer disconnects with error:

Hi!
I Try to use this plugin, but in my printers has two extruders. I did two sensors and connect its Pin 2 & 3.

1. How to explain plugin which sensor is swich on?
2. When in the first extruder finish filament sensor on and head go home heatbed too go down. I change filament, press Resume. Head go to right position and start print, but heatbed stay at home dont go up!
   I use default script which was in your plugin.
   Firmware Marlin for Ultimaker, Printer my, Alekmaker, (it looks as Ultimaker and use same parts.)

Would it also be possible to add functionality to shut off the heater/temperature control from the GPIO input? I've added a smoke detector to my enclosure and would like to be able to shut off both the printer as well as the heater if smoke is detected.

Hello,
I updated your plugin to the latest version and after reboot I couldn't see anymore the temp and humidity readings, it was just blank. I tried reinstalling, nothing. I wiped the SD card and started with octoprint and the plugin from scratch, still it won't show any values. I looked for the folders /.octoprint/plugins/octoprint-enclosure/extras/ but they are all missing now, they haven't been created when the plugin was installed via Plugin Manager. I no longer find GetHumidity.py and GetTemperature.py scripts in there, are they no longer required? I tried to add everything but I can no longer locate them at "https://raw.githubusercontent.com/vitormhenrique/OctoPrint-Enclosure/master/extras/GetHumidity.py ".
Please help me figure this out cause I've been struggling to get it to work but nothing. If I run the example scripts to check the sensors, it outputs proper values.
