Agreed, but there are minor differences in how the files are transmitted from RDWorks and LightBurn. Ruida doesn’t share code with us, though they do support our efforts with technical information and are forthcoming when we ask.
They sent us an 8445, along with details of the differences required in the communication for file uploading, TCP connections, querying the file list, etc, and never mentioned anything about upper/lower case - just that the filenames were now 2x longer than in previous firmware.
This really does feel like a weird interaction between something in that earlier firmware and something that LightBurn is sending the machine that it doesn’t like. We have multiple 8445’s in the company and have never seen anything like this (on this controller or any controller - never in the history of LightBurn).
