<p>Faulty endstop caused the printer (a traditional cartesian FDM) to try to move over the maximum axis limit at top, the noise has been atrocious, I don't see damages (apparently) but I'm wondering if this could have damaged something or the motors aren't strong enough to do any serious physical damage to mechanics of movement.</p>
<p>Could you clarify this?</p>

Printers are designed to be able to withstand an occasional crash as typically, no Axis Maximum endstops are installed. The 'atrocious' noise you describe hearing is the sound of the stepper motor having lost (or, in this case, repeatedly losing) steps. If you are worried, I would check that the X/Y Gantries are still in-tram and that the printer can still home itself without any problems.<br />\nIf this was a Z-Max runout (ie, printer tried to move too high), I would also check that the Z carriage is still on the Z axis Leadscrews before attempting to home, because if the Z carriage is not on one or both of the leadscrews, It is possible for the machine to engage them at different heights, throwing the X gantry out of tram or worse if only one leadscrew manages to re-engage.</p>\n"}, {'answer_id': 19045, 'author': 'FarO', 'author_id': 2338, 'author_profile': 'https://3dprinting.stackexchange.com/users/2338', 'pm_score': 0, 'selected': False, 'text': "<p>The noise you heard was likely caused by the extruder keeping turning, resulting in the belt stretching enough to jump a tooth or more.
