Massive Blobs left on print before color change.

Recommended Posts

Posted · Massive Blobs left on print before color change.

I have a mixing nozzle printer.  I'm using black and white filament.  I'm trying to print 2 identical objects side by side.  The issue is that upon color change, the print nozzle is dumping large blobs of filament down on the print.  Its not like ooze blobs.  This is fully extruded blobs..  I'm going to attach a picture for reference.  And this happens right before the nozzle runs over to the prime tower.


Someone please help.  i'm going insane!!
