BIGTREETECH Pi V1.2 Control Board + Octopus V1.1+ 8Pcs TMC2209 V1.3 Stepper Motor Driver Kit Upgrade Running Klipper for Voron 2.4, CoreXY, VZbot 3D Printer DIY Motherboard

Octopus and drivers have been great. The missing star is because the bttpi is underpowered and struggles with attached USB cameras. I get 1-2 frames/sec, so will probably switch to a pi 4 or 5 to address that.

This is probably the most frustrating control board I've ever used. The Raspberry Pi that comes with this was DOA. No matter how many times I flashed an image to the SD card, it just wouldnt boot. Just a solid red light. I would then move that same SD card to a real raspberry pi 4 and it would boot just fine. Given this, I decided to forgo the klipper route and try just flashing with Marlin to get the printer running in the meantime, and after days, I have not been successful. My biggest issue at this point seems to be getting an LCD to work. Tried setting it up with a RepRap Discount Full Graphic smart controller I had lying around and was able to get the graphics to work, and clicking the encoder button worked, but the minute I tried to turn the encoder, the controller would reset itself. Spent hours going over the pinouts from the screen to the pinout in the config pins file, and then back to where they are defined and all appear to be correct, but no dice. So I decided to then try a MKS TS35 V2.0 screen I had laying around and it was even worse. I cant even get an image to show up on the screen. Then we move onto the power issues. I gave up on the screen and was trying to connect to the board via serial usb. The connection was inconsistent at best, and when I was able to get it to connect, none of the motors will work, despite having the stepper motor power posts connected to the PSU. In fact, the only thing I have managed to get to work at all using this board is heating up the hotend. Thats it. At this point im done with this board. If I could give zero stars I would, and if i still had the boxes this crap came in it would be on its way back.

I am building a custom 3D printer, and it works great, just as intended. Also, a great value for what's included in the bundle.
