I am printing with a SmartRap Core (corexy) printer. Last night I printed a tablet stand, just about the largest thing I have printed to date. It started very well but when I checked on it this morning I have this:
I am printing Inland gray PLA at 190 w/ a first layer at 195. .4mm nozzle, with .2 mm layers, and .2mm first layer. Is this caused by too low nozzle temperature? It otherwise is very solid and my last 1/2 dozen or so prints were at these same temperatures without any issues. Maybe bad filament?
The other problem is that this thing stuck to the glass bed with cheap glue stick so well that I broke the glass trying to get it off!
