Great video. Not for me with all the connections needing to stick out the sides of the screen though. I like how the hardware is starting to become more streamlined. Pretty soon i bet the mainboards just come with a pi in them. Not stick one on it but baked right in.
@Kapman's Basement Workshop right im aware of the manta board and that btt and mellow are creating there own versions with the shortage. I just bet they will move to all in one units pretty quickly.
So, question. If we used eMMc and loaded klipper. Connect using USB to the octopus board. According to what you’re saying it’s now powered and connected to the mmu. The question is.. can the USB and micro port be used to load gcode files like did old school?
My apologies if this isn't clear in the video. Some important points: 1. If using a Pi4/CM4 with eMMc, the microSD card slot does not work. You cannot use that slot to boot from and you cannot use that slot for gcode files. You must upload the gcode remotely using Mainsail, Fluidd or your slicer. But I think these methods are much easier that SD card anyway. This is simply how the Raspberry Pi CM4 is designed. 2. If the Pi/CM4 has eMMc, and you try to use the USB-c port for USB, it will disable every other USB port until you unplug the usb-c! This is simply how the Raspberry Pi CM4 is designed and is actually helpful as it makes sure enough power is available for the pi in disk mode and allows you to install the OS without issue. 3. If using canbus, the USB-c port can be switched to canbus mode and used for canbus. When doing this, all USB ports on the carrier (display) work fine. 4. I would not power the display with the CM4 via the USB-c port. It will draw more power that a single RPi4 and under load, I'm not sure the power output of the octopus can support it. But I don't know this for sure as I use a spider (if can't provide all the power). So I used an external Meanwell power supply mounted under the printer that is wired to the 2 IO pins as shown in the video for power as can be done with any pi3 or 4. Hopefully this clarifies things? I learned the above the hard way..... Thanks for watching!
You have not provided any specifics, but I had a similar issue (I think). The Pad5 probably isn't getting enough power. You should either: - Use a powered USB hub (recommended in the Pad5 instructions) or you could try what I did: - Plug the Pad5 into a USB3 port (can provide more power) and - Unplug everything else you can from the other USB ports that might be taking power Hopefully one of those options work for you.
@@KapmansBasementWorkshop I followed the instruction given to the T. Got to SSH into the board and all that. I had a feeling that it was working when I plugged it into the back of the Pad 5 but got a blank screen. I was using a dedicated usb power source. This morning I saw a note on the biqu site that the CB1 is not compatible with the Pad 5. This might have been my issue all along. Thanks for your response my friend.
@@ezyfnef That is not what I would have expected. Surprising! I actually used a Raspberry module. So that might explain it. Sorry you had to go through that.
I agree. I wish they were pins. It not insurmountable, but it's not standard. That said, right now I have no used for them anyway. It's working really well.
Something nice about having a big touchscreen at the front of the printer.
It's funny that I never thought this would be useful, but now that I have it, it's great! I would not build another printer without one.
Great Vid! I appreciate the timing of the Vid drop since I just saw the PI Pad 5 on the BIQU site. Happy Holidays!
Thank you and Happy Holidays to you as well!

Actually, at least one of those exist today. The CM4 plugs right into the MCU. Thanks for the comments and watching!

@@jasonwoody8041 I think you are correct. I am looking forward to it!

I have the Pad5 with the CB1 and I'm having a hard time installing klipper and getting it to boot. Pls help

@@KapmansBasementWorkshop I know. I'm one of those guys that buys first and reads later 😂. Hope my experience saves folks some time and money.
Again, a very nice video. Thanks very much!
Thank you too!
Hello. Can this work on Raspbian OS?
That's actually what it's running on, Raspbian OS.
Ok, thanks fòr the làst guess, but I ĝo with octopus max ez.
That’s a great choice!
I send you my review on that
Great video! Thanks!
Glad you liked it! Thank you for watching!
The Pad5 wouldn't be to bad but female GPIO pins sorta sucks. Only reason I did not go that route.

Very nice, Thanks'
Thank you!
