What Marlin should for BIGTREETECH OCTOPUS V1.1

Hi.Please, I bought you a motherboard BIGTREETECH OCTOPUS V1.1. What Marlin should I download for this board and what configuration files? I want to replace the board with an Ender 5 Plus.Thank you in advance for your help.

Hello. The BTT Octopus will be happiest with the newest flavor of Marlin. Which is currently 2.0.9.1 and you can download it from github right here: Download | Marlin Firmware (marlinfw.org)

For setting up the board I have found 2 tutorials right here: OCTOPUS USER GUIDE (niceshops.com)

And here: BTT Octopus Setup Guide - UART, BLTOUCH - Make 'N' Print (makenprint.uk)

Done right when you power on your Octopus you should see this on your display at bootup..

For using VScode and making changes to Marlin there are a couple helpful and well spoken youtube tutorials here: VSCODE - Edit Marlin Firmware - How To - Chris's Basement - YouTube

And here: Beginner guide to editing Marlin firmware - step by step - UPDATE IN DESCRIPTION - YouTube

Thank you for your help.

Anytime. If you need a mount for your Octopus I have 2 tray designs that will bolt up to that aluminum extrusion with some m4 or m5 hardware and some drop in T slot nuts.

That's great, thanks for the help.

Hi.
Please who has this board BIGTREETECH OCTOPUS V1.1? Where can I find configuration files for Ender 5 plus or what should I set in platformio.ini
[platform]
src_dir = Marlin
boards_dir = buildroot / share / PlatformIO / boards
default_envs = mega2560
include_dir = Marlin

So there are a few ways around where you are. you need to change the default envs away from the mega2560 and to BIGTREE_OCTOPUS_V1

Alternatively you could just click on the little alien/ant head icon on the left column on the screen. this is the icon for platformio.

Once you click on it a drop down menu will show up and from there you can find your board and when you click on BIGTREE_OCTOPUS_V1 a sub menu will open allowing you to build in that environment without making that change to the default envs.

Once built and without having the usb connection you can click on the explorer icon at the very top of that column on the left.

Then you click on .pio

then you can click on build

and then you can click on BIGTREE_OCTOPUS_V1 and scroll down until you see the firmware.bin file.

Right click on it and select 'reveal in explorer' When that window opens up you can simply right click the firmware.bin file and send it to a microSD card you have plugged into your PC. Put your microsd card in the Octopus and it will flash itself when you turn the power on.

Hi.
I don't know how to do it. I rewrote default_envs = BIGTREE_OCTOPUS_V1 in

Configuration.h -
#ifndef MOTHERBOARD
#define MOTHERBOARD BIGTREE_OCTOPUS_V1
#endif

I set env.BIGTREE_OCTOPUS_V1 (Marlin-bugfix-2.0x)

When I try to configure, it reports an error: Unknown MOTHERBOARD value set in Configuration.h.Attachment 16804

So that part of the configuration.h should look like:

#ifndef MOTHERBOARD
#defineMOTHERBOARDBOARD_BTT_OCTOPUS_V1_1
#endif

I have the latest version of FM.src_dir = Marlinboards_dir = buildroot / share / PlatformIO / boardsdefault_envs = BIGTREE_OCTOPUS_V1include_dir = Marlinextra_configs =#ifndef MOTHERBOARD #define MOTHERBOARD BOARD_BTT_OCTOPUS_V1_1#endifNow it's reporting an error: unknown OSError exception code 22 - 'C: \ WINDOWS \ System32 \ cmd.exe': Invalid argument*** [.pio \ build \ BIGTREE_OCTOPUS_V1 \ FrameworkArduinoVariant \ PeripheralPins.c.o] Error 127unknown OSError exception code 22 - 'C: \ WINDOWS \ System32 \ cmd.exe': Invalid argument*** [.pio \ build \ BIGTREE_OCTOPUS_V1 \ FrameworkArduinoVariant \ variant.cpp.o] Error 127unknown OSError exception code 22 - 'C: \ WINDOWS \ System32 \ cmd.exe': Invalid argument*** [.pio \ build \ BIGTREE_OCTOPUS_V1 \ FrameworkArduino \ HardwareSerial.cpp.o] Error 127unknown OSError exception code 22 - 'C: \ WINDOWS \ System32 \ cmd.exe': Invalid argument*** [.pio \ build \ BIGTREE_OCTOPUS_V1 \ FrameworkArduino \ HardwareTimer.cpp.o] Error 127unknown OSError exception code 22 - 'C: \ WINDOWS \ System32 \ cmd.exe': Invalid argument*** [.pio \ build \ BIGTREE_OCTOPUS_V1 \ FrameworkArduino \ IPAddress.cpp.o] Error 127unknown OSError exception code 22 - 'C: \ WINDOWS \ System32 \ cmd.exe': Invalid argument*** [.pio \ build \ BIGTREE_OCTOPUS_V1 \ FrameworkArduino \ Print.cpp.o] Error 127

So I managed to compile it according to this guide: https: //www.youtube.com/watch? V = ATu_XkyDIJI Nevertheless, it did not work during the compilation, the last few days I had a window with antivirus, I had the impression that it is just an advertisement but when compiling, I was also shown and wanted to confirm permission to compile, I clicked to enable and compilation continued and failed. I started searching and found that an ativir had been installed without my knowledge. I uninstalled it and turned on Defender in Win and now the FW can be compiled.

Awesome. It should all be downhill from here. If you are using any touchscreen or tft display make sure you set the baud rate to 115200 in both Marlin at the top of configuration.h and also in the tft itself. 250000 is too high and creates communication instability with the tft displays. LCD displays like the lcd12864 do not care about a baud rate so if that is all you have set your baud rate to 250000 for the best performance from that board.

Thank you for your help.
