Versions of RPi 3B+ - does it matter?

Please Login to Comment

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

The Raspberry Pi foundation doesn't make the boards, they only design them. Kinda like Nvidia Reference. I don't think there is a difference, if there were the foundation would shut them down. I personally use the Element boards, because that's what they carry at a local shop.

Ah, well that explains it. Thanks!

+1 what Phiatterbutt said. I use canakits on my stuff too, and they don't cost much more than the sketchy off brand parts.

Thank you. I sort of wish they let you choose what parts you want to make your own kit. I plan on getting this heat sink (I've heard good things from this Group on it) https://www.amazon.com/gp/product/B07CTSNZYK/ref=ox_sc_saved_title_1?smid=A3NP42NNBY1RI6&psc=1 and Nocura fans for the Pi and Meggy (my printer).

Before you buy the fan I would try just the heatsink. I have that exact heatsink for my Pi's (use them for 24/7 SETI) and I don't think it needs a fan. You could always add it on later if needed.

Oh, cool, thanks.
Peace,

Wow, that heat sink is wildly unnecessary. Especially considering that the octopi image is headless, it has no graphical interface.

Not to mention it'll auto throttle itself when approaching temps around 60-70C. Sending serial data also produces little heat and is of little overhead for an SoC.

If you like knowing how your Raspberry Pi's are running, and I do, the first thing I install is RPiMonitor, which you'll find here https://github.com/XavierBerger/RPi-Monitor - easy to install, creates its own set of web pages with RRD graphs of temperature, disk space, performance - you can even hook it up to external temperature sensors.. Beats logging in and running top

Do I install that on the mini card that has OctoPi on it? It wouldn't let me do it from within OctoPi

What you need to do is plug your pi into a monitor / TV and keyboard and log into the operating system or ssh - secure shell into your Pi from another computer - have a look at this. https://community.octoprint.org/t/finding-the-pis-ip-address/844

If you need ssh on a Windows PC, use this. https://www.chiark.greenend.org.uk/~sgtatham/putty/docs.html If you are using a Linux machine you can just ssh pi@octopi.local or ssh pi@theip address, eg ssh pi@192.168.1.21, or whatever your Octopi's IP address is. The user account is pi, the password is what you set it to when you installed Octopi. Then follow the instructions exactly in RPiMonitor's installation guide. You access the finished installation by http://192.168.1.21:8888. I wouldn't install anything else from the command line except RPiMonitor - I use a dedicated Pi like most people for Octopi - but I have about another seven or eight doing other jobs.

That sounds exciting. Thanks. My Pi just now arrived - it's so tiny :)
I'm getting ready to boot her up.

I own that heatsink for my Pi's. I have to say it works really good. I use three of my Pi's only for SETI running 24/7. Before that heatsink I was using those cheap little square ones and my temps were in the 50C range (I think, it was a while ago). With this heatsink it is around 10C lower.

Oh, I’ll be using the Pi to learn Python as well.
Peace,

OEM is always best. Check out the Canakits on Amazon. I like the one that's heat sinks, 2.5 amp power supply and the pi. You can print any number of cases from here so no point in getting that. Should be around 45$ for that kit. You'd also need a grade class 10 microSD of around 8-16 Gb and that shouldn't cost more than 10-15$. I'm using an 8 Gb and it's plenty of space.

Thanks! I ordered the just the board and heat sinks. I also ordered an appropriate power cable with an on/off switch. I have all the rest of the cables.

I remixed two designs which are not ready for prime time (I want to make sure the board fits in it first), but here's a picture. I will pick up a fan for the new case once I figure out what size fans my printer takes. Might as well change them out all at once.

You're welcome. That's a really nice looking case.

If you're new at this I'll give you head start. 0.2 mm is a pretty standard tolerance for printing with. That's assuming you've calibrated your e-steps.

Thanks - the case is primarily a remix of this https://www.thingiverse.com/thing:1810943, but I wanted an octopus and cable slots.

I'm using Cura at the moment while I study up on Fusion 360 - that's scary to me, I can't even figure out how to rotate something! Give me icons like Cura has!

I've leveled my bed, but don't know what e-steps are...? I've been toying around with calibration test things and trying to tweak my Meggy into giving me good prints (Anycubic I3 Mega All-Metal). I've only been printing since the tail end of January. This is a lot different from weaving and spinning wool.

Peace,

MY FAV PI ( raspberry pi 2/3 case )

Fusion 360 is pretty good for design. As for rotation inside of it, select the object and press M to move/rotate then capture position.

Lars Christensen has really good tutorials.

Oh, thank you for the link. One of my goals for this year is to learn to design in Fusion and that link will certainly help.

With which program was it sliced and support structure added? This looks much more delicate, then the rough support I had. Just finished a bigger print.
