BIGTREETECH Octopus V1.1Control Board 32Bit SilentMotherboard Support 8Axis

Worked well at first. Fan stopped working after. Not sure if it was my fault or not

The board overall is well made and the connections are robust. I chose this board to update one of my printers to dual z axis and dual extrusion. Could have gone with SKR Pro, but I liked the fact I could set the voltages for various components like fans and inductive sensors. I have a mix of12 and 24 volt fans running, with no extra hardware to modify voltage. Setup info Isa little.scarce but if you Google."BTT octopus setup" you should find a guide. Even Wifi was easy to setup. You simply had to drop the firmware file on the SD card labeling the wifi firmware "esp3d.bin" the bootloader does the rest. Very critical you name the firmware files appropriately. Would hate to flash the wrong firmware on the wrong board. Overall working well and happy with my purchase.

If you want a fully loaded motherboard for your 3D printer, this is it. Its impressive how many ports and features on the board. Follow the guides online, or find some useful Github repositories and youll be up and running in no time. I personally use it in my Voron 2.4, works great and has supported all the extras i've added.

Exceeded my expectations. Very well made and functioning flawlessly.

Working on my old Prusa which was in RAMPS. Now I can call my project Octusa.

Great board for a machine if you can find the files for but a DIY project it isn't a good one to use. These are very particular on its set up and not a easy plug and play.

This is the second one of these I have bought for different projects. This one is going into my Voron Trident build. Easy setup, works great. No complaints.

Make sure you test the board when you receive it. Amazon is sending returned items back to new customers. One board was completely DOA and Another board was fried on the fan control circuit. These are great boards, but just check your board as soon as you get it

Used as a massive major huge upgrade for my sidewinder X2. Lots of motor, fan and sensor i/o make this the perfect board. Marlin 2 firmware compiled for it without any issues (once you get your toolchain all set up). Now running independant Z axis, inductive sensors on x,y and z and I'm about to re-add the filament runout sensor, and some RGB LEDs. Perfect for the DIYer.

Like all BTT products, this board is amazing, been using it for my Voron 2.4 build and it is flawless and very performant

This thing is a true multi-tool of a printer control board, covers just about anything even the most advanced printers could possibly need.

New motors, pulleys, drivers and this board, my printer now moves like it will hurt you if you were to stick your fingers in the wrong spot. Excellent. Before with a stock board with onboard drivers doing the same would make it skip steps. I've got room to upgrade with this which is great. Kinda wish the thermistor chip wasn't a tiny smd mod, but otherwise this seems like a great board so far.

For the applications in 3d printer builds I do, it works like a charm.
