Just for the record, all those messages and dialog structures come from the printer through the prompt host action commands. None of this is hard coded in OctoPrint but generated on the fly based on input from the firmware. So if something is misleading there, or should be reported back to Marlin so the UI for it can be fixed 😅
see this is why i subscribe to you, ive seen this feature alot while compiling marlin but had no clue what it did, then boom heres your video on it. i love the idea of power loss recovery using this. its only a matter of time before someone with enough coding skills makes that addon.
Have you ever had much luck with filament out sensors on the graphical menu on a Bigtreetech TFT?? I have a TFT24 V1.1 - It works really well on the Marlin text menu, but on the Graphical menu the head moves to it's park position and looks like it just locks up, but I suspect it it because it's not showing any kind of notification and there is no way to progress. Any ideas? After watching you video I was wondering if 'Host Handling' needs to be enabled as the screen pretty much acts as a serial communications board (as far as I can tell) - but then again it would be strange that the text version works! It's the same problem same the latest firmware version and the previous version.
The only way I have ever gotten it to work is by plugging the sensor into the screen. Some folks have said action commands will work with the touch screen, but I haven't tried it yet.
Hey Chris - Great video. As someone who has just bought an Ender 3 S1 this week, this was super handy to understand. However, what wasn't clear in the video was how you went about updating the firmware. From gaining access to the firmware that's installed onto the printer, to opening it on software on your machine, editing and then writing it back. As a late comer to 3D Printing, this maybe something people are more familiar with on older units? (Sorry, just found it - th-cam.com/video/W6zYvRgGr3Q/w-d-xo.html)
As a beginner, nothing is clear AT ALL about this software. Documentation is not structured, everyone just throws a HUGE bunch of random information at you without telling how to use it.
I like your video and the fact you explained things thoroughly. However, this is the first video I've stumbled upon. I would have loved to know how you opened that file, where it exists, what software you're using, etc... I have the firmware updater plugin for OctoPrint, but I don't really know where the Marlin firmware file is or how to get to it. Have to keep searching...
It's kind of a long process. The first thing to do is get VScode setup. Check this out. th-cam.com/video/JWUcnkjeNU8/w-d-xo.htmlsi=GDE9afwun2YNatKp&t=131
I’m trying to figure out how to do this and access that file. Is it some other program I need. Right now I have a raspberry pi4 running octo print. Would this require something else or is the coding somewhere simple and I’m overthinking?
i have a TFT 35 and i use octprint to print, would my sensor be plugged into mainboard with host_action enabled or would i plug into the TFT board also will the firmware on the TFT need to be flashed to account for this upgrade while being done through octoprint to see prompts on display. and lastly is there not a way to wire the sensor to GPIO on Pi? it seems the sensor direclty to the pi would cut out the middle man and allow octoprint to handle all aspects of the run out process
With host action commands, you will want it plugged into the mainboard. No, the TFT shouldn't need an update, as it would just be a serial controller for this. There is, th-cam.com/video/ChjwIGxnivw/w-d-xo.html
I have a btt tft50v3 and those host commands and prompts do show up and i can interact just like the lcd screen. Just thought u should know as u mentioned it cant.
You would need to have a configuration for your printer that you could update and compile. If you are starting from scratch, start here. th-cam.com/video/Ib188-ACa08/w-d-xo.html
Thank you for this video. This is something I've been waiting for, and Host Action Commands is more powerful than I expected or hoped. I can see lots of uses coming along fairly quickly.
Hey I have the Ender 3 S1, and I have been looking into enabling this setting for weeks, but something about the vs studio software version and the extension versions are completely broken so they think there are always errors with the files even with a completely freshly unpacked Marlin 2.1.2.1 folder, and always fail to build. Where would I go to get an already edited Firmware file, even the example config files for the STM32F401 Chipset would be perfect, I just can't build and I can't seem to find pre-built firmware files
It's really hard to find pre-builts that do exactly what you want. There are people of there that sell this service, but I don't know anything about them. marlin.crc.id.au/
Hey Man I really cant seem to get a grasp on this stuff. Is there any way I could get you to give me a firmware version that i could use for my ender 3 v3 se that enables host action commands?
@ChrisRiley could I get you to do it for me? I would be forever greatful. I am just no good with this stuff man. I could pay a small fee if youd be willing to help
@@ChrisRiley what is recompile? what programs are you using? how do you get this onto the printer? you seem to assume we know waaaaay more than we do in this. do you have a video that explains all this? will this work with creality's ender 3 v3 se?
Great video, very easy to understand. This looks like a really useful feature. I've often been stood in front of my printer and wanting to cancel a print, but have to grab my phone and do it through one of the Octoprint apps, otherwise Octoprint would just keep feeding the printer Gcode. Just the ability to pause and cancel prints from the LCD make this worthwhile, but starting the print currently loaded on Octoprint will be awesome.
Chris! I LOVE LOVE LOVE your videos! SUBSCRIBED !! But hey, I have a question about Octoprint, based off your video of turning a computer into a octoprint server. I am using a mini computer, just as small as a raspberry pi and it works great but! There are some great plugins that let you control relays, lights, and really whatever you can think off. The only problem is, its done by controlling the GPIO pins on the raspberry pi. Well users like myself, who are not using a pi, do not have these pins. Is there a way to control the pins on, say an arduino connected via USB to the compiter running octoprint??
Thanks! That's an interesting thought. I am not really sure, but that would be fun to try. You can interface with USB, so i don't know why we couldn't make it work somehow.
i wish 3d printer enthusiast were more sudo users, as for me aspiring to be one, i super appreciate your content man, i've learned a lot and improve super awesome skills viewing your channel, like the multiple instances on the rpi, i love you man keep up the fucking amazing work.
Great!!!! I have been pulling my hair out over this one. I have the BTT smart sensor. I did not know why I keep getting the menu Item Purge More / Filament ON/OFF all the time. I am going to try now and test. It would be GREAT!!!! To have my BTT Sensor working again. I have Repetier Host so I am going to try the HOST_ACTION_COMMANDS and see if it works. No big deal if it does not work. Thank You.
i was wondering if you had a tutorial on how to set up the bl/cr touch? because when i try to home my printer (ender 3 pro on the creality v4.2.2 board) the probe doesn't activate and my printer doesn't go to the home state because my bed probe doesn't activate.
Can you do this with Klipper?? I switched to klipper awhile back (i believe i followed one of your videos to do it) and I think the M600 command is the only draw back with klipper... But getting M600 working and getting these host action commands with it would be AWESOME!
@@ChrisRiley You sir... would be a god if you can bring this to the community! I know its been done before but the people who have done it have not really shared the information and unfortunately the klipper devs don't seem to really care about this functionality.. kinda odd seeings how most printers come with a filament run out sensor..
Just wanted to say THANK YOU Chris!!! I needed like the first 2 minutes and 30 seconds of this video to get that message cleared. I'll delve more into this topic soon to play around with HAC. Working on an Octopus 1.1, Ender Extender (400x400x500 print volume), Octoprint on a Pi.
That was super helpful. I've had a smart filament detector that I just wasn't bothering to use because it didn't play nicely with Octoprint. Thanks to you it's now up and running. Brilliant!
With that, and the right plug in, I should be able to have Octoprint Text me a message if the filament jams, or If I need to go back and switch colors without having to tie the filament switch to the computer running Octoprint.
I love your video's like this!!! This makes me actually want to get filament run out sensors as my 4 printers all run off of Octoprint! Thank you for sharing !!
This is game changing! Going to have to think about how I want to use it. I don't use the Marlin plugin for Visual Studio Code. May have to try and see what I am missing.
Christ this has been a feature on repetier server since god knows when. I really wish it got as much attention as octoprint as its far superior. I run 4 printers off 1 pi with ease.
Thanks for highlighting this new Marlin feature! I failed to notice it when I upgraded to 2.0.9.3. Your attention to detail and showing examples of various scenarios is much appreciated. Love this kind of video. Makes you want to dive right in and start experimenting. :-)
Great video as always. Big fan. But as far as power fail protection, I've been using a reasonably sized (650VA) UPS to cover any short power glitches, but all that would really be needed is some OctoPrint plugin to talk via USB/serial port to the UPS for signaling and, as you said, write the position info back to storage. My issue is that typically during extended power outages the bed cools and parts self release. There is no recovery from that other than glue or solvent welding.
Just for the record, all those messages and dialog structures come from the printer through the prompt host action commands. None of this is hard coded in OctoPrint but generated on the fly based on input from the firmware. So if something is misleading there, or should be reported back to Marlin so the UI for it can be fixed 😅

For the S1, you will probably have to start from an example. Something similar to this. th-cam.com/video/TQtocLwCp44/w-d-xo.html
this will effect how TFT screens work as well. There were a bunch of issues with those as well.
I could see that. Interested in doing some testing.
