Octo4a  

Yes

I run a Raspberry Pi 4 with Octoprint.  

No

So you don't run octo4a. You run octoprint.

O4A as in OctoPrint on Android?

Anyone got octo4a running on the mini?

Just to clarify: Are you referring to the OctoPrint on Android project? We get a lot of questions on running things on the RPi 4.

pi4

Sorry - if you were referring to the android app, that would not be me.  I am running octoprint on a Pi4.

Got the mini supported.

Yeah that's why I listed it as octo4a. And not octoprint. 

I got the USB id's added. V1.0 now supports the Prusa Mini

RE:

Can you elaborate... I am not able to connect with latest version 🙁

Thanks

RE: Octo4a

Are you using an otg micro USB cable?

RE: Octo4a

Thanks for the reply... Yep, octo4a says it is connected to the printer. See screenshots. Octo4a is running on an old Samsung S7.

Any ideas?

RE:

I could do some more testing, by choosing the 'CDC serial driver' allowed me to connect to the printer 🙂

RE: Octo4a

Thanks for posting this. Today this was the most useful thing on the internet for me!

RE: Octo4a

For anyone else who happens by here:

On my first attempts I got a "printer not connected" message on the phone (a non-rooted Pixel 3), but that came down to the cable. Once I got a good cable, it pretty much just worked.

For the serial driver, I used "CDC Serial Driver"

I used the OTG adapter suggested here: https://3dprintbeginner.com/octoprint-for-android-recycle-your-old-phone/

I used the printer profile settings given here: https://help.prusa3d.com/en/article/octoprint-configuration-and-install_2182

I didn't install any plugins or anything. This is my first experience with OctoPrint, and I have to say, using it on a phone (with the built-in camera) is pretty slick.
