yes pete
that is finally, controls with feedback loop
having acces to such data, or seeing how the autocorection occurs, should give you a glance
is not only printers, or head woble ... the loop has no clue that there is a printer
it does not matter, loop has no clue that there is a router, a mill, a lathe, etc ....
the loop can react on predefined paterns ( kind of adjust mode ), or dynamic ( real time )
is all about numbers, is not woblle, or whatever else ... is only numbers
statistics
a machine can perform smooth on a path that looks like /\/\/\; the toolpath from g-code, even if it is sharpy, will deliver increased smoother motion as droop increases, without altering other parameters; and here we go again, right pete ?
the cnc zone letter from last year, showed that this thread have had many views in it, but if i look at it, there is nothing constructive so far, only that you where keep going forward like other replies where not there ... this thread, was not a conversation, was only your stataments ...
okumas can detect this at servo level ... thus, it simply knows the pattern for acceleration, and can display a message once it detects anomalies
some vibrations are too gentle to be sensed by the servo feedback loop, like those generated by small cutting forces; for example, finishing a large heavy expensive part, may come with vibrations becuase of high rpm, and or chip evacuation, but those vibrations occur near the cutting edge, with no diff for the servo; to protect the expensive part, senzors are there in the spindle head / kindly
