https://www.soliforum.com/topic/7853/duo-20-head-of-extruder-1-rubs-across-last-layer-of-extruder-2/ Tue, 30 Sep 2014 00:15:27 +0000 PunBB https://www.soliforum.com/post/67338/#p67338 So during my latest print I noticed the bed vibrating alot.  Taking a closer look, I noticed the cause of this was from the second extruder head rubbing across the ABS layer put down by the other extruder.  I checked my calibration and everything is within spec.  Is there anything I can do to correct this the rubbing stops?
