I didn't think it was the mlt because the layer time was less, but you were correct. it seems the mlt is not a fixed border (cannot remember if it was that way before) when going from a layer time that is less than the mlt time, but print speed is gradually adjusted down. It seems that if the layer time goes longer than the mlt it is not gradual, it just move from adjusted to full speed. is that the case?
print temp is 145 with XT.
thanks for the help

I guess you use a low percentage infill and thus for most of the layers the minimum layer time (expert settings) is hit and the print speed is slowed down.
However, The underextrusion at the end when jumping back to nominal speed should only be a few mm long. What temperature are printing at?
