<p>Usually the hardness of the material is considered primary for nozzles used with abrasive filaments.  Has friction between between nozzle material and abrasive filaments been considered? It seems that friction as well as hardness would play a roll in how long the nozzle lasts.  Perhaps, this is considered with ruby tipped nozzles.</p>

If this is the actual problem, of fiddling with the cables might have caused this, an alternative solution is presented as I\'ve experienced similar behavior.</p>\n<p>If one side of the bed is higher than the rest, even when rotating the glass bed, you might experience that the nozzle carriage is tilting on that side. E.g. when using a Bowden extruder assembly, a too short Bowden tube (or cables in a non-Bowden setup) the tube (or cables) pull at the carriage causing it to lift at the furthest points from the extruder; this tilting can cause the nozzle to go up a few tenths of a millimeter.</p>\n'}]
