Hello everyone! A friend gave me his printer to repair, I have no clue what brand it is and I don't know anything about the components. All I know is that it's some kit he got off AliExpress years ago. I fixed the major mechanical issues, though there's still some stuff I need to do, like adding a cooling fan. Problem is, the Firmware isn't set up with a cooling fan in mind and I'd like it to be controllable, but since I have zero information on the printer I can't exactly download the firmware from anywhere and I'm not about to dig around sketchy Chinese sites to get a firmware that might work... So I was wondering if it's possible to somehow read it off the board or something? I haven't used this style of controller in my builds for a while now, so I've kind of grown used to having the config and all that on an SD for the duet... I could configure a new firmware but that would require some trial and error, especially in regards to the mystery hotends in there, since it is a dual extrusion setup. Also I'm glad I remembered this forum. I haven't been here in a while heh... https://reprap.org/forum/read.php?13,892047,892047#msg-892047 Mon, 20 Apr 2026 15:26:32 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?13,892047,892089#msg-892089 https://reprap.org/forum/read.php?13,892047,892089#msg-892089

Best you can do is dump what settings you can get to
