Multiple printers dont work

I've bought my second printer, and wanted that to run on octoprint too, but didnt want to buy a second pi to run on. So i followed Chris Rileys video on how to install octoprint on window to run multiple printers.

I made the IP adress for my ThinkPad static, and i made the first printer and the second printer When i accessed the first install i got to see the setup process. But when i accessed the second install i didnt see the setup wizard, it was already setup like the first install.

I tried to install plugin on one instance, and saw that the exact same plugin was installed on the second printer. I then tried to change the title and appearence (color) of the setup, and when i changed it on one printer, it automatically changed on the second printer.

What have i done wrong? In the video that Chris Riley shows, he changes the title and color, and it only applies on one printer and not both. Have i missed something?

Some info:
Printer one: CR10S
Printer two: CR10S PRO
Laptop ThinkPad T430 with Windows 10
Octoprint latest version.

What command are you using to launch each instance?

I’ve made a folder called it octoprint.
What I do is:

  1. cd C:\octoprint
  2. octoprint serve —host= —port=5000

That’s what I do to start it.

You need to specify a basedir for each instance. Append --basedir with a unique path that indicates where the config directory should be located.

Can you please give me an example on how to do thath? I've only done what was done in the Youtube video.

I've just made a comment on Chris's youtube video suggesting that I would never put more than one 3D printer on an OctoPrint installation. Feel free to uptick that if you agree with the sentiment.

I agree assuming you are referring to using separate venv's and basedirs. Otherwise the video seems decent.

So how could I run multiple octoprint installation on the same windows machine?

I’ve tried to make both C:\printer1 and C:\printer2 and installed venv in each folder and installed latest octoprint in each folder. But I still they’re connected somehow

If each instance already has it's own venv then you just need to append the --basedir argument with the path to where the directory should be. See
