The full story
The poster bought a UV galvo laser for about $500 that came with only a Chinese control program, and shelved it for around three years. When they needed it again they fed Claude the whole program, Java and DLLs, and asked it to crack it.
There was no documentation. Claude decompiled the program without being asked, worked out the Chinese, pulled out the response and comms tables, and ran tests with the poster to see what each command did. When it hit a bug it built a comms sniffer to see the full communication structure for files. The result is a GUI the poster says is far better and fitted to their use case, in under five hours.
