Hi, I’m talking to the TinyG using JSON mode. What is the best way for my host code to be notified when a specific line of G-code (which has an N-number) has been completed?
Right now the r:{gc:{n:{..}}} responses tell me when that line of G-code has been enqueued for the planner, but I need to know when the line has been *executed*, not when it has been enqueued.
The qr:{} responses let me monitor the fullness/emptiness of the queue, but it seems exceptionally difficult to correlate those numerical fullness/emptiness levels with a precise line of g-code while running at full blast. This is even more difficult because a single G-code line may create more than one queue entry, so the correspondence isn’t one-to-one.
This has to be something people use a lot, so I’m guessing there’s a simple way to do it that I’ve missed.
