BIGTREETECH Octopus V1.1 Control Board 32Bit Silent Motherboard Support 8 Axis TMC2209 Stepper Motor Driver Compatible BTT Pi V1.2/Pi 2 to Running Klipper/Marlin for Voron 2.4/CoreXY/VZbot 3D Printer

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.

It took a lot of youtube and chat gpt but I got it working. This is for a scratch build and my first printer. Take your time and it will work.

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.

A great board for a Voron, hard to beat for the price.

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.

I have had very poor luck with BTT in the past. I thought I would take a chance and change from my fysetc spider to the octopus 1.1. I have been trying to get this card to work for six months on and off I get so frustrated. I have to set it aside for a while, then I pick it up figuring that it must be the firmware or my set up or some mistake that I might’ve made. In the end I think it’s just a crappy board. BTT has a little to no quality control. I have read other reviews that say that it took them three boards to find one that actually worked. I do not have the patience to try three boards. I will be reinstalling my spider board. This was a huge waste of time and money.

I bought this for my voron project. Actually I have bought three of these because the documentation was so bad I went through three boards. The first one I bought in the end of 2023 and I blew it because of a problem with getting the right jumpers on the board. It did not come with directions and the directions for this online from the manufacturer is abysmal.The second one I blew because I uploaded bad firmware which by the way no where did it say in the documentation if you upload firmware incorrectly with bad settings you will destroy the board.The third one I got help from someone in the voron discord otherwise this wouldn't have happened with me finally getting a working board.The board is very high quality good high tech stuff for a 3D printer but lack of documentation from the manufacturer is something this company struggles with big time. Thanks!

Very well made motherboard
