OctoPrint version 1.8.7, OctoPi version 1.0.0, printer Ender 3 v2 Neo, firmware 1.1.6, browser Chrome, operating system Win 11
I'm not sure if my Raspberry Pi 3A+ has enough power to run Octoprint, Some Plugins, Octolapse, OctoScreen and a Webcam. I have had a weird issue already where my ender 3 v2 neo was endlessly trying to extrude and not moving the nozzle. And when i tried to pause the print through octoscreen, it didn't do anything. I then tried to login to the web interface for octoprint and it stated that the print was pausing. It never paused, so I had to press the emrgency stop button. I have only had this issue since I installed octoscreen today. I also get the warning about undervoltage. I am using the offical Raspberry Pi power supply that came bundled with my Pi 3A+.
The Pi 3A+ actually has the same SoC as the 3B+, so it is just as powerful. The only difference is that the A+ has only a single USB port and no ethernet. It is actually slightly less power-demanding than the 3B+ because of the missing USB ports and ethernet controller, which may be a benefit for OctoPrint use.
Guys I literally just made an account to ask about RPI 3A+. Just bought one, 512mb ram and I'm having trouble with the Ender3 v2. Can confirm that webcam works, however, to get over the low voltage errors I had to tape the last pin of the USB cable so that it wasn't drawing to the printer.
Anyways, my big issue right now is that it halts the nozzle randomly during prints. I worry that it's not powerful enough...
I have two potential things that could otherwise explain it 1. I'm using wifi.. but should be fast enough, I have an AP like 3 meters away, and 2. I'm using the PSU + PSU_TAPO plugins to power on and off the printer.
I will try plugging directly in to the socket tomorrow. But can anyone else confirm if this 3A+ is NOT SUITABLE? Someone else said you should have min of 2GB of ram..
Please read the rest of this thread including the links. The RPi 3A+ uses the same parts as the RPi 3B+, just less of them. It is a suitable host for OctoPi / OctoPrint. 512MB of memory is enough as the RPi Zero 2 W has the same memory capacity and it is on the recommended list.
Your problems with the Creality Ender 3 v2 are NOT specific to the RPi 3A+. This forum has many topics about problems (and solutions) with Creality printers. I would suggest you start your own Get Help topic, fill in the template with your details, and we will try to help.
