@fcwilt Yes, that's it. I connect to the firmware via http-request.
Let's say we have the following case: Someone processes a movement with a specific feed rate, for example F1000. Afterwards he/she wants to increase the value by 500, but doesn't know the last F-value which was specified in the first run. To increase the value by 500 I need to know the last specified F-parameter to add the increment.
THANK you very much!
