Unfortunately, there is no progress bar that does this. The existing bar shows the transmission of the instructions for the laser. To estimate how long it will take, there is a small countdown next to it.
I have asked something similar here. ([Bug] Wong Values at Progress Bar)
The problem with an accurate progress bar is that lightburn doesn’t know exactly where the laser is now. Most lasers don’t transfer that without slowing down the whole process. That is why it is not currently displayed.
