many many hiccups (thousands)

Any progress on this issue ?
-
I don't know if the hiccup issue is still being looked into or if it has been shelved. I just ran a 6 hr print using 3.5.1 and I am still seeing the same issues. Here is my m122 for the tool board that did the printing. Note the 'hiccups 27753'

Can you share a video of the printer in action?

@Phaedrux, while not impossible, I don't really know what I am doing. Could you give me a hint as to what you expect to see? There is no apparent (at least to me) difference in printer behaviour between a printer that shows hiccups vs one that doesn't produce hiccups. I don't know if maybe one would see choppy motion for example ... but there is no hint of choppiness.
