Octoprint on Raspberry Pi 4

Hi there, new and overall in 3d printing and raspberry. First of all I would like to connect my prusa i3 mk3s (which I am waiting for) from my networks.

First of all I can not choose what type of raspberry pi 4 to buy.

Raspberry Pi 4 Model B - 1 GB RAM
Raspberry Pi 4 Model B - 2 GB RAM
Raspberry Pi 4 Model B - 4 GB RAM

I especially want Octoprint to run and think about the surveillance cameras.

First of all, I would like to ask you about the Raspberry Pi 4 Model B with wifi signal. The point is that the printer will be on the first floor at one end of the building and the router is on the opposite side of the building, therefore what a good receiver has raspberry.

I have seen that people to finish the LCD touch screen on prusa and I would like to know what it means and especially the benefits.

Sorry for my English

The 2GB version of the Raspberry is probably the best choice for what you're doing if you're considering one or two webcams.

Any of these support both 2.4Ghz and 5Ghz wifi but are the same with respect to effective distance.

For any of the TFT upgrades, make sure that there are good step-by-step instructions and buy what they ask you to buy.

Lastly, I would suggest that you should purchase one or two Class 10 microSD cards for your installation.

What type of screen would you recommend to me.

If you are going to try to use the same mod as Jerlo, he states that it is only compatible with Kuman screens. I have Octoscreen running with a Chinese 5" 800x480 capacitive-touch screen (hdmi) and like it a lot. https://github.com/Z-Bolt/OctoScreen

Can you give me link becos i found only this

I whant only size this screan whitch he use but whit octoscreen and realy easy setup or good manual like say [OutsourcedGuru]

What TxBillbr said: go with the same one or abandon that tutorial. All these are different. So the instructions for loading one might not work for another.

Sorry I meant that I just want the size of the display. I would practically leave it to you who is simply tried and I will not have problems with it

Your tutorial indicates that this 5" screen is what they're talking about.

Personally, my (different) printer has a small 3.5" screen and I've replaced that with a 10.1" SunFounder.

Yes, that is sold under a bunch of different names. It uses HDMI for the video and a usb connection for the touch part. The hardest part is 800x480 is not a standard VESA resolution, and you have to make an entry for it in the Xorg configuration. If I wasn't so strapped for money, I would have gotten a 10-inch one. Plus I have three printers to feed :smiley: ... I will try to find the resolution setup I used if you want to try that one. Also Chris Riley (Chris's Basement Youtuber) has an excellent video on setting up Octoscreen on a 5" display. If you search for "5 inch raspberry pi touch display" on Amazon, you will get lots of hits for the display.

@Avarax none of these Chinese screens have good documentation or videos. So as long as they have drivers for Raspberry Pi buster, they will work. By default they come up in 640x480 mode. The article on how to make 800x480 work is here https://www.raspberrypi.org/forums/viewtopic.php?t=154961

I highly recommend you watch Chris's video. It was very useful for me in setting up Octoscreen.

When you win the lottery, head over to elotouch.com.

A couple of months ago I was in a going-out-of-business sale at a furniture store and they had a humungous (probably $5000) TFT display console (same company) that they used in the sales channel and I was desperately trying to get them to sell it to me. :laugh:

Can you give me some typ on amazon.de for screen whitch good documentation and his price is normal or love ?

I from midle EU becos amazon DE

Sorry, My German is not good enough to shop on Amazon.de. Any touch screen that works with current raspberry pi can be used. Best choice is capacitive touch and hdmi connection. I cannot be responsible for your choice. I can only advise of what worked for me.

And which are they?

Any touchscreen that uses usb to communicate touch and HDMI to deliver video. This way you are using native pi tools rather than some Chinese guy's driver written for some other linux system. Sorry for the delay in answering, I've been heads down rebuilding a printer.

I used the Adafruit documentation to setup the 800x480 resolution on the 5in screen.
