Best alternative Raspberry pi4 (RPI4) with touchscreen for Klipper

[Buurman]

Hi guys, since the RPI horror continues, at least for a couple of months (and I think longer) what is the best alternative.

I am using the 4" BTT touchscreen with the flatcable and most alternatives dont have this interface on the board.

But maybe there is a good alternative for the touchscreen also, since I think I have collected 100 duckies already from BTT anyhow.

I have tried/looked at:

1. BTT adapter for CM1/CM4 and tried the CM4 board (also not available anymore) but coudnt get it to boot.
2. Orangepi 4 LTS 4Gb - 16GB - Still on the way, takes forever and is about 90 bucks, looks like having the MIP flatcable connectors.
3. Asus Tinker Board - Cant remember had some issues while setting it up in KIAUH

Above board were chosen since they have the flatcable connector, but maybe there are other options.

Well, open to suggestions/ideas!

What about using this with the matching CB1 from BTT? It is still running great on my V-Minion.

Good option but need the manta board, does it not?

The CB1 is made as a drop in replacement for the CM4. So the Manta boards and the BTT PI4B will both accept either compute module.

[Buurman]

Yes, the manta board can hold a CB1 or CM4 onboard, but with the adapter, you can use it as a regular PI option.

No matter whats next to it.. I just coudnt get it to boot, maybe the CB4 is broken, I expect.. tried 2 adapters..

Now that's just showing off! There's a fortune sitting there!

Yes, I AM jealous (hits F5 on rpi locator). I was observing the shortage with mostly detached interest, now I need CM4 for a different project. All I have "in stock" right now is a 3A+ for either a V0.2 or Rook project.

Ordered a OrangePi4LTS a few weeks ago and it arrived. well, thats the biggest challenge tackled I guess...

This seems to work nicely, just installed it with Debian (Bullseye) Server version. (there are also other versions and a desktop version. Go for Server.

https://drive.google.com/drive/folders/1W0Bm-GGvVqgiDeSdEy_PSGlA23ahMGC6

Image it with BalenaEther on a SD (and yes, finish verification) and insert this in the OrangePI and power it up.
I temp use a USB C connector for it, but you need a 4.0mm/1.7mm plug if you want to power it by adapter and use the usb C for data transport to the Octopus.

So now its booting, I advise using a network cable, find the given IP in your router or other DHCP server.

SSH into it with default user/pass orangepi/orangepi

install KIAUH (install tool for 3d printer software, works amazing.

https://github.com/th33xitus/kiauh

Install 1,2,3 and 5 in my case...probably later also the Telegram bot, since its awesome.

Go to IP adres in browser and boom.. klipper!

I've got 4 OrangePi 3LTS your right a little more challenging to get it up and running. A nice feature is the EMMC that you can upload the SD card to then you no longer need the card to boot. Webcams are a little trickier to set up. Check out the Test Camera section of the manual. Also, HDMI is the default for display, so if you use the DSI connector for display, you can configure the pi for that.

Yes, I need to try that still

[PFarm]

sudo nand-sata-install, boot from EMMC, "warning overwrite" confirm, 1-ext4.

[claudermilk]

I thought there was a Klipper image for Orange Pi now? I'm sure I saw mention, but don't recall exactly which GitHub repository it's in.

[PFarm]

That would make it more attractive to people that aren't too techky! This guide is pretty detailed.

Could you beside this golden tip, also point in the direction of the touchscreen enablement on the display port?

[Buurman]

And I am always doubting what way around to put in the flatcable into the slots.. pff. One side the display, other side the orange pi

 

any tips would be good

Sorry my mistake the DSI flat cable was for the CB1 and CM4 that I did on my Voron. Only HDMi is available on the OrangePi. Not sure if can re-dedicate the webcam slot for display doubt it since one is an input while the other is an output.

Ah, yes the orangepi4lts has 2 webcam and 1 display port extra. Think I just put in the cable wrong, as happens often, should just write it down

Well, it looks like the famous BTT PiTFT50 will not work on an orangepi...

Guess I be putting it aside for other home projects... like it being a adblock/ popupbanner or so..

On that topic, I´ve lost the sale of my Zero 3 times now once I´ve said that  to the prospective buyers that the pi wasn´t included.

From an old job project I happened to have 5 Pi3+ and 4 piscreens at home and I´ve not lived the drama yet, but I´m actually starting to experiment in an spare SD the idea of running 2 (or more) klippers and mainsails to control the 2 printers that are slaved in my Lak tower to free one of the Pi.

The most feasible (and striaghtforward) option I saw was getting a cheap ultrabook or micro PC and run multiple images of linux on it to control as many printers as you wish.

This is, however a patch as you lose the "standalone" feature of each printer working on its own without external hookups.

I am running an Orange Pi 3LTS in my Voron 2.4.  Considering I knew nothing about Linux, Klipper, or anything else, it really was not that hard to get running.  I utilized a dedicated monitor attached to the OPi via HDMI along with a keyboard and mouse.  Once I had OPi running, the first thing I did was get the WIFI connected to my home network.  This made setup much easier.

The Orange Pi touch screen  is an option but my search shows AliExpress stores that I don't have a lot of faith in.

Had a strange issue with Klipprescreen not wanting to work at all after installation, manual or Kiuah .. just seeing the console.

Found.. eventually the solution, posting here for reference.
