I'm here quite tech savi... made the mistake of buying 8 gig... guesss I'm ready to beta test
So this has been my production server to use to print parts for my Octodash setup and Pi mount case. After printing everything i made a new install of Octopi 17 to regain Octolapse (author is working on it) and Octodash (author is working on it).
Also currently Hyperpixel is working but landscape is not possible.
Resource monitor has been fixed by an update to that plugin.
Everything else has been rock solid. Also I can confirm that things running faster is not any placebo. File reads/write fly on this. Upload a file? Nearly instant. Updates or installs? Super fast.
This is the future and I’ll be setting up my test server on it and test Hyperpixel on that one.
You’ll be just fine. So far, for me at least, only Octolapse doesn’t work. That is the only thing in the built in plug in list that didn’t work for me.
Everything else is rock solid and super fast.
The other things like Octodash/octoscreen/Hyperpixel are all additions that are not in the official repository. So use the built in timelapse plugin until Octolapse is working again.
Otherwise just in my experience anyone wanting to try a faster, more responsive setup could safely run this version. I’ve done 40+ plus hours of prints on it.
Do you mean that's not working on 64bit OS? I think it's a kernel driver version issue. I remember seeing some info from this repo about it.
It took me a bit of searching to learn that my new Pi4 is a 64bit box and not 32bit like every other Pi I've had. Now that I know I have thankfully found this post. Is this the "proper" way to get Octoprint running on the Pi4 8GB? Is "OctoPi" essentially just Octoprint running on top of Raspberry Pi OS?
I'm going to try it regardless...just curious to learn more.
Yes - Octoprint is written entirely in Python, runs in Python environments and has an instance of haproxy running locally to separate the Web front end from the print processor [I think], TBH I've not looked into it too much, but that's the basic principle.. Octopi is a prebuilt image with Octoprint already installed on top of Raspbian, you could take a standard non desktop Raspbian image and install Octoprint on top, but why would you when Octopi has done most of the heavy lifting. Its great, IMHO.
The Pi4 uses different kernel files because of the chipset architecture, which are all on the /boot partition, as are all the other boot files for other Pi's original, zero, A, B etc, - the bootloader works out which type of Pi is booting from the card and loads the correct image files.
I posted over on this thread since it seemed like a more accurate place to get support...but I am curious if anyone has had an issue wiring the serial connection from the Pi4 8GB to the Prusa MK3S. In my estimation, this should work exactly like the Pi Zero did (minus power).
Yes currently the screen works but cannot be used with Octodash or Octoscreen as those require landscape orientation.
To get precise all Pi4 are 64 bit (older ones might be also I don't know) however they have been releasing Raspbian only in 32 bit. It is only with the release of the 8GB version they had to provide a 64 bit version to use all the RAM.
Pretty complex in general. There is both 32bit and 64 bit Raspbian both of which should run on all Pi 4 models. Then there is Octopi 17 and 18 which are 32bit and 64 bit respectively. Then there is the Kernel issue which affects both versions of Octopi (well mostly the plugins - because running without plugins I think either Octopi 17 can be upgraded to Kernel 5.4. Octopi 18.1 is already on Kernel 5.4.
I'm not really 100% but from my limited understanding the Kernel issue is the biggest issue. It just happens that the 64 bit version of Raspbian comes with the latest Kernel. You can cause the same issues if you sudo apt-get upgrade on Octopi 17. Because it will update the Kernel to 5.4 while it is still 32 bit.
Even the differences I see (speed, file handling is super fast) could in theory be the new kernel or the 64 bit OS. When it is safe to sudo apt-upgrade my production server we could make that comparison.
FYI, there's an FAQ entry that answers that question:
I can't find the plugin Octoprint-Exclude Region, I installed the version OctoPi64-0.18.1 ... is it not yet compatible?
yeah it seems like the plugin uses python 2 and that image uses python 3
Hello everyone i am new to the forum and new to octo and raspberry. So i purchased a pi4 8gb without knowing the 8gb model is not fully supported and found it would not boot octopi 0.17.0 as in nothing would happen. i tried re mounting with different image programs and no luck. the only thing that worked was a beta from printedweezl, i am a bit unsure tho as to the best way to continue with the 8gb pi4, is there a stable official version that will run on it? or what is the latest version of printedweezl beta as the one i found was on a dropbox page. but unsure if its the latest.
It is an 'unofficial' beta - built the same way that the OctoPi 0.18 official beta is made, but targeting the (also still in beta afaik) 64bit image from the Raspberry Pi foundation. From reports in this thread, it seems to work quite well. This should be the latest one:
First off, I wanted to give a HUGE thank you for making this work on the Pi4 8GB. I didn't do my homework before purchasing and just got the latest Pi for printer, only to find out the base Octoprint didn't support the 64bit 8G. I've been running it since you released the beta and it's working great overall.
One question, I'm trying to get a touch display working so I can use touchui or octodash. I keep going in circles on dependency errors for TouchUI, primarily can't get chromium-browser installed. Octodash installed fine but fails to startx. If I use the base install of Raspbian the display works just fine. So is there a display package I can install on Octoprint that will fill in the gap between Octoprint and Raspbian?
Disregard - Reloaded the SD from scratch, restored my backup and installed the desktop environment via your install script and it's working great up to that point now. I'll sort the touchui or octodash stuff elsewhere if I continue to run into issues.
I think I'm having the same problems as you. The file loads and queues. Status changes to "starting" and nothing happens. The heaters don't active. It just sits there. I removed OctoLapse. I can control the system from the Web UI. But queueing a print never works.
The 0.18 build listed above, Pi 8GB, Latest OctoPrint (1.14.2). Prusa slicer / MK3S.
Were you guys able to make the raspbi camera work?
Yes it is working Thanks to @PrintedWeezl (you're the man) OctoPi64-0.18.1-beta.
So trying to find the configuration file in etc/default where is it on this version?
What configuration file are you looking for? Configuration of what?
