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

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.

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.

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.

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.
