Hello,
I am trying to connect my Sculpfun s30 pro with LightBurn (the latest version) but without succes. The software can not find the laser and when i add it manually it shows “Ready” but the laser does not respond for G0.
I checked Lasergrbl software to be sure it’s not some hardware problem but the laser connected without any problems and it works well with those software.
I would appreciate any help because Lightburn seems to be much more user friendly so it would be great to try it.
First thing is to try to toggle the “enable DTR signal” option in device settings. Does it help?
Thank you ! Yes it did
Could you explain what this function does on Sculpfun machines please?
It’s not Sculpfun specific, but a controller thing. Here is the explanation from Rick from another post:
On Arduino hardware DTR is used to reset the controller. On other stuff like standard serial controllers, DTR means that the sender is available to talk to and the signal is required in order to initiate communication. So Arduino has kinda messed it up for everybody else. The correct way to use serial communications is to turn that DTR signal on, but if we do that every time it resets the Arduino. Hence, you can choose to set it or not.
And I think that Jason wrote in some post that LB tries to detect the correct setting while automatic laser detection. But this often fails or if the laser is added manually, the setting might not fit.
Understand thanks
Never heard of this before, but Ortur and Algo use their own flavor of ESP32 so maybe thats why!
Thank you
Or they have a better board design 
Maybe those other boards tried to copy as much as possible from Arduino-based boards and inherited the DTR problem, though the ESP controllers don’t need an Arduino style boot loading process.
I didn’t dig so deep yet.
nor me, but i better just in case!
We do have our own hardware and firmware flavor but i dont know the ins&outs exactly. Only a simplified understanding on how it works!
Thanks again
