Help identifying a generic 3D printer control board
« on: April 08, 2021, 05:18:10 am »
Hello all,

Recently got my hands on a 3D printer board pulled from Shenzhen (photos attached). I've been wanting to use them for a project, but the provided firmware is a horribly mangled version of Rep Rap from 2017 that's basically unusable. Random crashes, half Chinese UI, etc, etc. The only reason I want to use it is because I already have a bunch of them. I have access to the source code, so I know the pin definitions and a few other bits of essential info, but my main goal is to get Marlin running on the board instead of what's currently on it. I've tried editing the pin defs in Marlin to upload firmware to the processor on the board (STM32F104RET6), but the only thing that happens when I do that is the board stops communicating with Windows and I have to revert back to the old version of the firmware.

I feel like this process would be infinitely easier if I had more information on the board (name, manufacturer, anything), or if anyone knew what I was missing in the Marlin config files to get this thing working. If anyone had any ideas for finding this board online, I would be glad to hear it!

P.S. Wasn't sure if this went into the 3D printing section or the Beginner section, but since its more a question about finding a specific part rather than "3D printing" itself, I figured I was better off putting it here.
