BIGTREETECHOctopus V1.1 Control Board 32bit Compatible TMC2209, TMC2208 Stepper Driver, Support DIY Klipper Firmware and Raspberry-Pi Online Printing for Voron V2.4 Upgrade 3D Printer

Changing stepper motor driver jumpers stinks! If you like to struggle, then this board is perfect. Otherwise this board has been the biggest pain regarding stepper jumpers. Each section has so many jumper leads , I would keep putting the jumper on lead below about a million times. And the jumpers they provide are crap and the the size of a molecule. Perhaps it is just me, but I never had to "struggle:" with jumpers before. But I am used to jumpers that are taller. The things disappear if you are unlucky enough to drop one, I dropped them at least a hundred times, sometimes using needle nose, or tweezers!Otherwise it is a good board. It is probably 3 just me struggling with the jumpers. I had to complain somewhere after spending an hour trying put a jumper on the top of 4, three stacks for each motor port. And dropping .

Besides actually not being able to update via usb for klipper, if you manually update the firmware, there are still issues with the USB itself. Bought one could never connect it, bought the 446 version and have had zero issues.

One of the fan connectors I wasn't using dangled into the pin for the fan power options. The fan itself acted as short between the 5 volt and 12 volt power option. It literally caught the board on fire, and burned up all 7 of my 2209 stepper drivers and my btt50 display, And to top it off it defaulted to 100% power to the hot end and bed And almost went into thermal runaway with the hot end. Thermal runaway is no joke this is something that should not be possible. especially, with a high-end board. At the least you should be using non-conductive pens to protect them from making contact, And this should not be in the board design if it is that dangerous. A switch would have been much more safe.

I ordered this board three times, hoping for better results each time. The board has some very good possibilities, but way too many problems. Have tried reconfiguring it many times, but always either get errors, or the stepper drivers simply will not communicate with stepper motors. Unfortunately the return window has come and gone, so cant get my money back now. I will never order this board again.

took forever to get it working for me many attempts to wire it up properly as the manual can be confusing at times and is missing important details like how the board power in, motor power in , and bed power in all need there own connections to power supply however i did reorder to see if it was just a dead board and the second one worked for a bit but just died randomly so would not suggest ordering
