with dev/ttyACM0 on baudrate 250000. Thank you for your help

anyone can help me with my s4 and octopi on my raspberry pi? When I click on connect it's stay on "connecting"

To start, check your connection settings in octoprint:
- make sure the COM port is correct (if in doubt, try another from the list!)
- check your baud rate (250000 should work from memory, it's a while since I've been to the connection settings page).

Let us know how you go with that...

Octopi2.local is, well, local to the octopi just like 127.0.0.1 is "LocalHost" to your PC. You cannot reach 127.0.0.1 from external network interface so your computer is not able to resolve the hostname to an IP address. Well, unless you have the bonjour service installed as recommended. Do you have that installed?

Update:
I don't have two raspberry pis to try it, but on my PC Octopi would not connect using octopi.local even with the bonjour print service installed. However, when I added 192.168.1.107 octopi.local to my windows/system32/drivers/etc/hosts file in windows, it resolves just fine. Add an entry for both and be done with it. The only downsides would be that you would need to do this on any PC you wanted to use that way and your octopi would need a static IP address.

I used raspi-config.

Doh! You are actually using two separate devices, not two instances of Octopi-server? Hmm....

Try on your windows PC to change your hosts file to list IP and hostname for static routing. You may have to do this in your router as well.

Hi

Does anyone know how to setup 2 octopi to run 2 separate printer?  I tried to change the hostname of the 2nd server to octopi2 but I am having trouble connecting to it via "octopi2.local".  I can still find it using the ip address.

Anyone have any idea how i can make the "octopi2.local" option work?

Thanks

When you say you changed the host name, you did this in /etc/hosts file?

I had been having trouble getting OctoPrint installed onto Adafruit's image.  I went back to my original plan of putting the Adafruit TFT kernel and files onto OctoPi.  The problem was that Adafruit's files were based on an older version of Raspbian, and there were module version conflicts between OctoPrint, OctoPi, and Adafruit.

After some experimentation, I found that I could use OctoPi version .8 (current version is .9), and install the TFT files onto that image.  I still have some details to finish, but it looks like it's going to work after all.

Intriguing idea...being able to run Rasbian images, Linux, or Android.  I'm going to get one, but I'll have to finish some current projects before I get a chance to play with it.

I wonder what sort of community support will spring up around it.
