Hello again hubs!

I’m back again after much trouble and countless searches on google. I’ve found myself stuck on yet another one of my projects.

I’m attempting to network my four 3D printers. Now I’ve looked a lot into what software I needed, and the one that best suited my needs was Repetier Server. Not many people seem to know about this one, or at least use it, as I’ve found AstroPrint and 3dPrinterOS to be much more popular variants. One of the things I like about Repetier Server is that I’m in control of the interface, there’s no middle man’s website hosting it for me (That I know of).

My issue? I’ve got everything all set with the correct firmware on the Raspberry Pi 3, I’m even at the point where I can connect to it VIA it’s IP address from any network, my problem is with connecting the printer.

On Repetier server, I need to select the Port that the printer is connected to. This is immediately problematic as there are over 60 options to choose from. My options being Virtual Delta, VirtualCartesian (Those two are just features to allow you to simulate printer connections) /dev/tty, /dev/tty0 (That last one starts at /tty0 and then goes all the way up to /dev/tty63), Followed by /dev/ttyprintk, and then finally /dev/ttyAMA0

Now I’m unsure of what port the printer could possible be connected to (I started off trying to ping every one for a chance it would connect, but soon realised I need an alternative way as I’d need to do this process every time I connected a printer)

I know the Baud rate of all my printers is 115200, the only concern I had was how to tell what port the printer is on.

Thanks in advance for any responses!

Did you figure this out? I’m running Repetier server on a Raspberry Pi 3 and I believe I use dev/ttyAMA0 to connect to the USB port on my RADDS/Due board.

If you are still having an issue, let me know and I’ll double check to see which port I’m actually using. Once configured, there is no need to have to select the port each time you connect.

I ended up giving up on Repetier server and began using 3D Printer OS instead. It doesn’t do quite what I want it to do but it’s been getting the job done.

My concern more so was how to figure out which printers were on what Pi’s as I have two machines connected to each.

Thanks again so much for the reply!
