Hmm, that is strange. I just ran it in simulation mode on my laptop and the
feed rate override responded as expected, slowing down and speeding up in
response to the slider. However, it's less smooth at low override
percentages. I think I know why, I'll run some further tests tonight.

Also, what are your pc specs? It might be a performance issue if we're
getting very different results.

Does the max velocity slider work ordinarily? The way the code was written,
the max velocity is only set when a segment is first created. There are
fields like vMax in the trajectory planner, but they weren't used during
tpRunCycle.

Thanks again for your help!
