No Diving! But seriously,
Lightburn isn’t open source and the release folder is the product that is available to customers. The source code isn’t even available to a clear majority of the LightBurn team, let alone enthusiasts or customers.
The confusion may be caused by the crackerjack Linux guys managing a library patch for gstreamer to Ubuntu 20.4 and 18.4 by telling the builder to build with one thing (gstreamer) from Ubuntu 16.4. It’s more of a ‘Hey LightBurn, while installing - look here for this book’ than anything else.
I learned a thing or two that day.
I appreciate the clarity here.
I would be interested to know which baud rates are selected in Candle and lasergrbl. Someone posted a while back that they had to hard set the baud rate to 115200 in LightBurn to connect with a particular Sculpfun or Atomstack. This is not shown to be necessary with a vast majority of Sculpfun devices. General USB noise and line length are considerably more common - You’ve clearly dispelled this. There is also a switch in LightBurn (in Device settings) to Enable DTR signal. I would also like to know if Candle and lasergrbl use DTR as part of their communication process.
115200 - confirmed here:
