My Prusa Mk3s sometimes makes a strange "noise" while printing.
At the moment it looks like, that the noise appears only, if the head moves fast while printing a curved line.
It seems that the noise is coming from the print head.
I cannot separate whether it comes from one of the fans or from the extruder drive.
I tried to provocate the noise manually with octoprint by doing some fast movements with or without running fans.
I also extruded filament with maximum speed.
But i never heard the noise....
I want the printer to do all movements as in the print, but without extrusion. If the noise appears then, it's clear, that it doesn't come from the Extruder.
--> Is it possible to start a print with heating & extrusion disabled?
