Review on BIGTREETECH High Frequency Printer Control 12864Lcd: Enhance 3D Printing Efficiency and Precision by Chris Dildine

I want to start by saying that this board has AMAZING potential. Maybe it will reach that potential in a few years, but right now there are virtually no setup guides on the web and no help other than poorly translated instructions from the companies. I had no help troubleshooting and neither did the company's support as they completely ignored my email for over 2 weeks. On the first board I tried the X motor connector seemed to work fine, but on others there was no output at all. After overcoming some initial stumbling blocks and writing some Marlin code. (Note, the instructions are obviously wrong and if you follow them your code will not compile. Tip 2: Don't download Visual Studio, start with Atom with the PlatformIO extension.) I sent my board back and asked Revain to replacing it, my goodness a replacement came, and I continued my testing. I had a random idea that maybe my stepper drivers were wired the other way around all along and that would explain why my motors weren't working. FUN FACT: if you connect the drivers in reverse and turn it on for even a second, your entire board will be fried and it's all useless. I don't want to underestimate the potential of this board. It has a really impressive list of features. Maybe in a few years this comment will be out of date, but someone who really knows what they're doing should take this board and make a comprehensive guide online, and the company has some interesting bugs to fix. (For example, I don't know, maybe connecting the stepper drivers in reverse instead of frying the whole board will trip the breaker?) If you know what you're doing, I think you stand a chance of making this board work. Really good, but if you're new to Marlin or 3D printers like me, this board isn't for you.
