@deme said in Direction/Velocity Vector of Printhead movement:

@dc42 Thanks for the suggestion. A few other questions:

Is there a referance how often the OM can be pulled (in a sec) without losing performance?

I wouldn't advise polling the whole of the OM much faster than DWC does it, which is normally 4 times per second. Maybe 10 times per second wold be OK. However, you could poll just a part of the OM (e.g. the current move direction vector, if we added that to the OM) more often because the amount of data returned would be so much smaller.

Is there a way to force the RRF to parse an undefined axis and stream the values to OM? Or does that make absolutely no sense? For example to do something like that: G1 X10 Y10 U90 for LED Ring Position 90 deg relativ to the x axis.

I can't think of a way to do that using the current firmware.
