Latest Lightburn can´t download the file to the Ruida controller, but 0.9 can

This is a known issue with some Macs over USB to Ruida. We are working to resolve. This is worth review.

Version 1.0 - MacOS issues with Ruida

I think I finally understand what’s happening on MacOS / Ruida / USB. Apple has a bug in the driver that talks to the FTDI chip - it’s ignoring what’s called ‘hardware flow control’. Similar to a conversation between people, it’s possible for one computer to send data to another too quickly. If the receiver starts to backlog, it can turn on a signal that says, “hold on” to the sender, then when it gets caught up, it turns off that signal and the sender resumes.

I’ve tried to tell so many people this, but the ease of USB makes it very attractive. We’re genuinely considering removing USB as an option altogether if I can’t figure out a way to make it reliable.

I have a side project we’re working on, using a Raspberry Pi as a relay. It would plug into the laser with a network cable, and connect to your home WIFI network, and LightBurn will talk to the laser through the Pi. Simple setup, will cost about $50 (price of the Pi, power supply, SD card and cable), and throughput is 600kb/sec in testing. Not ready for release yet, but getting there.
