BIGTREETECH Pi V2, The Next Generation of Raspberry Pi Alternatives For Your 3D Printer

[@drewgraham7877]

I like the on board storage option. Great review!

[@kamogrigoryan1096]

Just in time. My artillery genius motherboard is burnt out. I want to replace it with a klipper. I wanted to take this board.. thank you

[@EtherealProject3D]

You will need an MCU as well, A Manta M5P paired with a CB2 would be a solid combo for the Genius.

[@NamelessUnicorn]

Can you use gpio pins to control relays from klipper tho ?

[@robertoguerra5375]

11:39 I can’t believe rapsberry pies are still scarce and expensive… is the silicon drought still on? Is there any octoprint screen that can show the webcam, and a 3D model matching the gcode?

[@Grimmwoldds]

3:22 I think that's the NPU. The BTT pi v2 is listed as only having 1 mali GPU core with a rockchip SoC, so that 1 core is part of the CPU chip. That would mean the separate chip is an NPU for spaghetti detective like activity(computer vision) which is fine at the .8 TOPs listed, but keep in mind that it'll heat up. it's essentially one of the newer Chinese "NPUs" which are just repurposed cheap/ugly CPU cores and some memory.

[@tempacc9589]

They are using the RK3566 chip which comes with an NPU by default. It doesn't do much for this installation but they probably just decided to market it. Any acceleration would need to be done through the RKNN library so not all models work out of the box which is a minus. It's not "repurposed CPU cores" though.

Does this SP5 with klipper print better than the K1? In the video the bed seems to swing like a seesaw.

[@EtherealProject3D]

@@raulelias2013 I would say its pretty on par if not a little better than the K1. I use my K1 mostly for ABS and ASA and the SP5 as my PLA and TPU work horse

[@redline3036]

Really wanting to update my mcu board on the swx2 just not sure which one. I have your pcb board and am wondering if it has an extra 5v so I can install knomi 2 with the stealthburner upgrade im working on. I can honestly say I'm not ready to give up on the slingers and not ready to get on the bambu train yet.

[@EtherealProject3D]

@@redline3036 The BTT SKR 3 is a great board

[@nickolascuartero7854]

I love the board overall but I believe that taking out tx & rx for uart is a big downgrade and secondly just why. I was wanting to have a cleaner setup with less big wires and save some usb ports for other stuff kind of a letdown.

[@TheFeralEngineer]

Uart5 works on pins 21 and 23. I've been working on a pi2 video to go over it, but time constraints are a pain.

[@nickolascuartero7854]

@@TheFeralEngineer I saw a post somewhere on reddit about that but I couldn't get it to work I even adjusted the armbianEnv file with no success. Maybe I was missing something idk. On a side note wouldn't this mess with your display if you are running one?

[@TheFeralEngineer]

@@nickolascuartero7854 it's a little unclear when modifying the armbianenv file. You need to put all of the device tree overlays you want to open up on a single line, you can't just uncomment uart5 somewhere down the list, you need to put it in the first overlay line that is uncommented. Also, it's important that you also have a ground connected. I didn't run into any display issues, but I'm currently running mine headless and connecting to it through a btt pad7 with a wireless connection set up in Klipperscreen.conf

[@Levisgil47]

What would be the best solution between the PI V2 and the CB2+PI4B ?

[@TheFeralEngineer]

Both are ostensibly the same, but the pi2 gives you the m.2 pcie capability for a small ssd

[@JFML1974]

SPI connector for the adlx is lost ADXL 345 😮😢

[@EtherealProject3D]

Yeah this is a bit sad that they removed that. There are USB options that will work just fine though.

[@barrymcbruce]

Just confirming that this is working with a BTT Pi TFT50? Also any chance of getting a copy of those board mounting and piTFT50 case / mounting files?

[@EtherealProject3D]

Yep it works with the pitft50. email me and i wall get you those files

[@barrymcbruce]

@@EtherealProject3D Thanks so much dude. Ive emailed.

[@varazir]

Was your old card a RPi ?

[@EtherealProject3D]

No, it was the BTT Pi v1.2

[@varazir]

@@EtherealProject3D and you got a DSI screen to work with that ?

[@EtherealProject3D]

@@varazir Not on the old BTT Pi, I had the display on an RPI4 but I dont use it much so I moved the display to this machine after getting the new BTT Pi V2

[@thatonesnowboarde]

@@EtherealProject3D How reliable is BTT boards?

[@EtherealProject3D]

@@thatonesnowboarde I have had extremely good luck with them. Ive never had one fail on me that was not from my own doing.

[@brandonedwards7166]

its stupid they did not include can bus

[@andyw8009]

I think it is worth mentioning that the new Pi does not support CAN BUS unlike it's predecessor...

[@EtherealProject3D]

CAN BUS can still be achieved using a U2C or the BTT MCP2515 SPI to CAN module.

[@andyw8009]

@@EtherealProject3D Yes, that is correct but that means spending even more money on a hardware which increased performance is not really necessary.

[@EtherealProject3D]

@@andyw8009 Even with the Pi 1.2, the U2C board would have to be purchased separately so you need to buy extra hardware to run CANBUS on ether board. The smaller U2C board that plugs directly into the 1.2 board is a cleaner install option and it is too bad they couldnt retain that option.

[@andyw8009]

@@EtherealProject3D I thought it was supported as it is on the Manta boards with no other component needed, turns out it does need the U2C board you mentioned, my bad ;) perhaps this is why they dropped it.

[@EtherealProject3D]

@@andyw8009 I think it was due to space constraints, adding the extra connector for the dsi port and all the extra traces for the M.2 port.
