I’m trying to build a firmware for an Ender 5 with a 4.2.7 board, and no matter what I do I get a build failure with no error messages. I’m stumped.

Huh - that’s weird. I checked the log and it says the OS ran out of disk space - which certainly isn’t true.
I tried a stock build for Ender 5 Pro - 4.2.7 board, and it built successfully. I also tried a build for my printer, and it worked.
Can you try it again and see if it fails again?

Hey there! Just got back to my computer. I’m on the east coast of the US, so sorry if these replies are delayed.
I just tried compiling a new firmware package using the exact same specs as above, and it was successful this time. It figures I can’t replicate the error as soon as I tell someone about it 😆
If I encounter the issue again, I will update this thread. Thanks for taking a look anyhow.
