It is possible to print with multiple printers? Maybe running various instances of OctoPrint? I dont know if Raspberry Pi will be able to do all the job.

It is only possible via multiple instances. I do not know if the RasPi will be up to the job of multiple concurrent prints either, I tend towards no, it won't.

Might change once I come around to #30

I didn't test printing simultaneously but I got two instances running on a computer by changing the /home/pi/bin/octoprint file to:

#!/bin/sh
OCTOPRINT_HOME=/home/pi/OctoPrint
MJPEG_STREAMER_HOME=/home/pi/mjpg-streamer

# start mjpeg streamer
$MJPEG_STREAMER_HOME/mjpg_streamer -i "$MJPEG_STREAMER_HOME/input_uvc.so -r SXGA -f 15" -o "$MJPEG_STREAMER_HOME/output_http.so" &

# start the webui
$OCTOPRINT_HOME/run --daemon start

# start the webui 2
$OCTOPRINT_HOME/run --daemon start --port 5001 --pid /tmp/octoprint2

Of couse you need to change "pi" to whatever username you're using. In linux you can request this in the terminal using:

@peteruithoven Doesn't this configuration use same configuration at ~/.octoprint ? You should add --basedir

I am interesting in trying this too. The PI quite possibly might handle two instances.
I can set things up now, and try it at the maker group where we actually have 2 printers.
@foosel Would be glad to update about this and document.

@guysoft Sounds good!

Also yes, you should probably use a separate --basedir maybe better --config per instance. I honestly don't know how sharing the uploads folder between multiple instances would work once you take metadata analysis into account -- it will most probably work as long as you don't try to start them up simultaneously.

Thanks for the tips. I'll try soon.
We're trying to use it to control at least 4 Ultimakers in Fablab Amersfoort. Really great stuff.

Both printers broke in the maker space. But I can run successfuly on OctoPi a second instance on port 5001 using:
~/oprint/bin/python ~/OctoPrint/run --daemon start --port 5001 --pid /tmp/octoprint2 --basedir ~/.octoprint2

I have three printers in the makerspace and I am planning to hook them up to one RasPi. Note that I will be running octoprint for monitoring only so see the status of the prints, how much time left , webcam etc.

I am thinking of cloning /home/pi/OctoPrint or maybe whole /home/pi/ into another instance(s) and run them in parallel as much isolated as possible. What do you think ? Or maybe we should start running Docker containers in Raspi, LOL ?

I know this thread is a couple years old now, but I was wondering how the B+ has changed how many printers can be run off one pi?

@notrub Well you are welcome to test it yourself.
You can start another instance of OctoPrint on OctoPi with the command given in the comment above: #113 (comment)
I'd imagine it should be possible.

I am assuming I can put a Raspberry Pi on each Printer and print to them from one workstation?
As each printer will then have a unique IP number, yes?

Is there a way to change the bonjour name? I've got two Pis setup and would like to change the name of one of them. I don't see anything in the network config. Where can I make that change?

The bonjour name is the hostname (that's sadly nothing that can be changed). So you'll need to change the hostname of your Pi. That can be done via raspi-config, see here on how to do that

Has anyone tested the max simultaneous working instances of OctoPrint? My school has 15-20 3D printers (2x UP printers, 10 Makerbot Replicator Minis & 5 Makerbot Replicators) and I was wondering how many Raspberry Pi Bs we are going to need? 😄

edit: specified the types of 3D printers (just more info, I don't think it is really necessary)

What version of Makerbot Raplicators?
Most of the printers you mentioned are closed-source and have no way to be supported in OctoPrint.
I would have love to see OctoPi in schools, but you might also want to have a look at 3DPrinterOS, they are built to handle dozens of printers.

Of course, you could always add some kind of cluster API control to OctoPi, and have one sit on every 2-3 printers. But I know none who attempted.

If by Replicator you mean Replicator 1, then it will work with OctoPrint and GPX, but if you mean the new 5th Generation Replicator, it won't work. And it definitely won't work with the Replicator Mini and I don't know anything about Up printers, but I suspect not there too.

MakerBot went to a proprietary and closed protocol starting with Gen 5 so the GPX plugin doesn't work with them.

Is anyone running multiple instances on the newest OctoPrint? I've tried two different methods, but neither seem to work. I think the configs have changed or something. I am running the OctoPi distribution.

I upgraded from I-don't-know-which-version of Octopi to octopi-jessie-lite-0.13.0 yesterday and could not get multiple instances of OctoPrint running again, even after disabling haproxy. After much wailing and gnashing of teeth, and a blue million reboots, I finally did this:

Preamble:
I have 2 printers, a MakerFarm kit & a Prusa i3 that I built from scratch.
Both run Marlin firmware. I mostly use Simplify3D ( MacOS ) for slicing
and have configured Samba on the Pi so that I can "Save Toolpaths to Disk"
and simply choose the smb mounted volume associated with the printer I
want to use. The saved files then automatically show up in the Files menu
of the appropriate OctoPrint instance.

I think that it is possible to have multiple printers share the same files.
My printers are different enough that doing this has no value to me. If I'm
ever able to get the 2 printers to behave identically, then I'll probably
pursue this.

This guide is terse and assumes a certain level of Unix knowledge. It's
really not so much a guide as a set of notes documenting the process in
case I need to do it again... I'm assuming that you can figure out what
to change to reflect your preferences ( e.g.: vi, MakerFarm-i3v, Prusa-i3 )

@DarkMatterMatt I have successfully got 9 printers up and running off of a single Linux Box. Printers: 2 Printrbot Simple Metals, PrintrBot Play, Prusa i3, Monoprice Mini, Ultimaker O+, Rostock Kossel Delta, Tronxy X2, and a custom job. Running prints on all simultaneously did not affect print quality, it did, however, tax the system to have all 9 mjpg streamers running with yuyv cameras 😛
