Versions of RPi 3B+ - does it matter?

by NaloMeliful

Hi,
I'm looking at the RPi 3B+ and see different versions or flavors such as Vilros, Element, and the Original from Raspberry. All say they are RPi 3B+. Does it matter which one I purchase? Are they they same? I'm going to be using it for OctoPrint and not much else.

Thanks for any advice you care to share.

Peace,
Nalo

New to 3D, want RPi3B+ advice

by NaloMeliful

Hi,
I currently use Ultimaker Cura (Beta) to print via USB on my new Anycubic i3 Mega. I’ve heard wondrous things about OctoPi and the RPi.

Am I correct in my understanding that the RPi is tethered via USB to the Printer but one can monitor from another device via the web or my home network?

If I purchase the RPI3B+ will I be able to download an STL and slice it on it? Or is the Pi strictly printer management?

Thanks for any enlightenment you can offer.

Peace, Nalo

RPI3 b+ with 3.5" screen

by Alter3go

Hi,
i recently purchased a 3.5" screen for my RPI 3.
I followed instruction to install the drivers, which seemed to worked as can see all the booting up texts.
I then followed the instructions to boot to browser with TUI
https://github.com/BillyBlaze/OctoPrint-TouchUI/wiki/Setup:-Boot-to-Browser

After the reboot and load, the screen stopped on a blank/black screen. moving the stylus on the screen, I can see the Octoprint log in screen behind the block around the mouse cursor.

the same when I stop the TUI and the Pi loads to the desktop. When I move the mouse with the stylus, I can see the wallpaper appear around the mouse cursor.

I have been searching, but cannot find an explanation for this.

anyone have experienced this before?

Thanks

problems with audio

by jbs

My audio stopped working a couple hours ago. I tried changing the audio settings in sudo raspi-config, but it still didn't work, what should I do?
note: I replaced the batteries in my wireless mouse around the same time, coincidence?

L298n motor driver with Blynk

by TheJadeRabbit

Hi, I could use some help with getting my project to work. What I want to do is control 2 DC motors with an L298n driver and a Raspberry Pi 3 from my phone via Blynk. I also want to control the motors with the joystick widget in the Blynk app. I got my Pi connected to my phone over wifi with Blynk, but I am having trouble getting the Python for the joystick to control the motors with the driver. If you could point me in the right direction it would be much appreciated.
