spiking issue

[anthony27]

Hi anyone had this problem, see images attached, seem to be getting spiky bits during the print, ithis is leading to warped prints ,
also there is a funny grinding sound when moving in the x axis?
the part is supposed to be a small box, also are the extruder fans supposed to be functioning during the print?

My first impression is that your temp is way too high, the plastic isn't cooling fast enough which leads to warping and spiking due to oozing and dragging of melted plastic.

thanks for the insight,

DjPrinter is right. Your temperature is way too high. Try reducing your temperature at an interval of 5 degrees until you achieve your desired 3d print quality.

not sure, I mean I am using the same temps as before the rebuild, could it be he nozzle is damaged or the aluminum block is out of position from when I put it back together?
