OctoPrint on MK3?  

Re: OctoPrint on MK3?

Ahhh.. I see.. So for a Pi, not Pi Zero?

I am not sure whether there is a long cable for the Zero, so for now, I am not sure whether we are going to get much flexibility on the location of camera.

Of course for the Pi zero. The cameracable is the same for all pi.

Surely not.. The Pi Zero connector is smaller, and higher density, so you need a special cable for the Pi Zero and the longest I have seen in 30cm.

Re: OctoPrint on MK3?

[The novelty of time lapse definitely wore off on me. I have a camera attached to the build plate on the MK2. But, like others 30mm is all I have found for the Pi Zero cable. I plan to attach a camera to the frame for monitoring and I am fairly certain I will not miss the time lapse.

You can use this extention board https://www.modmypi.com/raspberry-pi/camera/camera-cables/camera-cable-joinerextender-for-raspberry-pi and then just buy a normal RPI Camera Cable

Oh shit! 😮 You r right. Damn.
Okay... then i also need the extender: https://www.amazon.de/gp/product/B073DJB2W1
and a zero cable https://www.amazon.de/gp/product/B01MQMJZ5D

This is getting a bit expensive now.

Re: OctoPrint on MK3?

Okay, i got OctoPrint runing on my current machine since today. Without a working camera 😉 but hey, its a nice upgrade for 3dprinting and when the right cable arive till next week, everything should work fine. I will definitely use it on my MK3 in the future.

Here is my tutorial video on how to setup octoprint. Some Prusa specific info, but mostly generic.

If anyone comes across a good detailed thorough Mac tutorial for those less experianced, I have not found one that covers things in clear methodical detail yet.

I have a Mac as well. I can do the same thing for Mac. Its less stuff you need to download as you can use pico in terminal and ssh through terminal. Instead of Etcher, I use Pi Baker (I think thats the name). It has some extra features like being able to backup and image. Like if you only have 1 SD card and want to try Astroprint (Astrobox) but don't want to lose your entire Octoprint setup, you can backup the image first.

Are you good with Terminal?
your commands would be:
For wireless networks:
sudo pico "LOCATION_OF_SDCARD_BOOT"/octopi-networks.txt
enter your mac password
arrow down to your network part of the text file, uncomment it out and replace with your network information

for SSH
sudo ssh [email protected]
enter your mac password
accept warning
enter your pi password
sudo raspi-config

Comfortable with it, you sort of have to be to get any non conventional detail accomplished... but typically when people start utilizing terminal they leave out fundemntal steps thinking the details are obvious for everyone.

Which admittedly I am not well versed in the fundamentals to know how to make jumps from one idea to another because it is obvious, or fill in the details when not instructed explicitly to do so.

OK, I'll make another tutorial tonight on how to do this in Mac. Shouldn't take me long. I'm not celebrating Thanksgiving until Saturday, anyway.

Re: OctoPrint on MK3?

Really!

Thank you!

May I ask, because I wouldn't want anyone investing time fruitlessly...

Would you know if anything will be different from the Often speculated Prusa implementation?

From what I can tell they simply added a repetitive "busy" signal coming out of the machine to help the RP0W from disconnecting. Would this be a reasonable expectation this is the "only" difference?

But again...not very well versed in these things nor confident in asserting one way or the other.

Also I have read there are ways to construct "images" of the install, and people can just drop it on the card, almost plug and play considering they should all be virtually identical ?

Personally I would much perfer going though the steps, as I have had NO experience with the raspberry pi , and based on what I have seen, I would love to open up this door for possible future exploration, and this should be a perfect step to familiarize and gain some experience and confidence with the platform to not be easily turned away from lack of knowledge on the topic.

Thanks! 🙂

I have no idea what changes they have made, but you can bet I'll make a tutorial if there is anything drastically different in the process. The only thing I see me doing is soldering pins to the pi zero w. Octoprint itself may be the same, but the OS (Octopi) may be slightly different. I can make it super simple. I realized I may have omitted 2 small things in the video.

1) I didn't mention or wasn't clear that the wifi section is defauly commented out and you must remove all 3 # from the beginning of the lines where the wifi setup is.
2) The pi's only support 2.4Ghz wifi bands unless you get an adapter that uses 5Ghz. If you have separate SSID's for the 2 bands from your router or you have 2.4Ghz off, you will need to select the right one or enable it. I use different SSID's so I know which one to pick.

Re: OctoPrint on MK3?

Exactly details like that will trip me up, not having backend knowledge about compatibilities and obvious details to observe and be aware of.

And like you mentioned, I know I have done it many times before, but simply to be reminded to uncomment out a line, personally that can trip me up.

May I ask a question, how did you select the card size and card class to utilize?

If it is possible to estimate how much room does the OS consume, any other services that are likely to go on, and how much scratch space will likely be beneficial to have in reserve? Considering a time laps should not take too much space, yet video could dependent on bitrate over a particularly long print...

And will a lower speed card, specifically for this application, be particularly detrimental or even noticeably slower in actual use?

My hope is to utilize and repurpose a "slower" older card that was used in a sports camera for this task and replace it with a new larger model, simply as a efficiientcy measure.

But can easily get a card specifically for this task if it would be beneficial to do so.

1) Size, I used 8GB and it works fine in my other pi. The OS is pretty small, files you send to it are small, time laps videos can be large. I did run out of space previously with several pages of videos. You can have the pi automatically take time laps of everything you print. You can just download them to your computer and clear them from Octoprint to clear space. I picked 32GB for this reason. Its $12.99 on Amazon.
2) Speed. The 95 mb/s card I picked is faster than the pi can go, so you're not going to get performance boosts that matter on Octoprint. Probably a class 4+ would be fine. I'm not even sure a faster card for like a RetroPi distro would make any significant difference. When I was researching cards for RetroPi I saw an article that the fastest anyone got was like 30mb/s.
3) You can repurpose the older, slower card. I'm pretty sure the one in my other pi is from a Blackberry Curve my parents had ages ago. I'm pretty sure its a class 4 card. You can even keep the SD card in the Prusa and use that, but I wouldn't recommend it. Its going to take FOREVER. You will be using the pi to tell the 8-bit computer in the Prusa to write to an SD card and that's not going to happen at any reasonable speed.

Re: OctoPrint on MK3?

That was.my hope.

I don't want to create a bottleneck that will be a clear detriment to operation if a few bucks can solve the issue.

But at the same time, if I can have my cake and eat it too, I am interested in perusing different ways to go about it.

~How much extra space is avalible on a 8gb card when fully installed fresh?

Does octoprint have file system access that is easy to manage? I.e. People typically just keep their library of prints on there, or would it be typical to keep only the nessesary desirable items on there?

And again with the videos and time lapses, I have lots of archival storage, so I would always be pulling anything off that I wanted to keep.

And to go into some detail, assuming you might know, if you select "record every print" can it be configured to write over old data maybe?

Sort of ran like a "dash cam" where if there where a issue, you could go back over the problem and assess when and where it became a problem to hopefully avoid in the future on the next print.

The Pi is the likely bottle neck here. Actually, really, the Einsy board is more of a bottle neck. Thats why a Pi Zero W can manage it.

I'll double check when I get home, but I want to say that a fresh install with no plugins is ~1GB. Sliced G-Code files are in the MB range and Time Lapse (depending on settings) in the 100's MB range.

You can totally keep your favorite common prints on it. You can even keep those on the SD card of the prusa and print from Octoprint, but that removes 1 of the conveniences of having Octoprint.

The file system is easy to manage from the user interface. Each file has a few icons below them with options like Delete, Print, etc. The Time laps are managed from a different tab. They have a Download/Delete option.

There isn't an option to record over older files. There is an individual file created for every print. I use the option of take a frame on every Z change. So every time the z axis moves up, it takes a pic and adds that.

I use the time laps for root cause analysis. When I get a stringy ball of plastic, I can see what happened (object detached, tried printing in mid air where I needed support, etc.).

I think this is the correct link? Simply a direct link for others to follow.

Have some time, so going to give it a shot.

So , I think I worked though my little issues...

These are my "constructive criticisms" from following along as I was going though each step. They are all pretty minor, just thinking from a completely new persons perspective...which I am sure there will be many trying to accomplish this.

Rasberry Pi Notes

I had some trouble connecting, but restarting the Pi again, even after the advised restart, before I could access OctoPrint via the web interface.
