Topic: Layer Separation
I am trying to print this card holder: http://www.thingiverse.com/thing:82998
Warping was easy to understand as an issue, which I've mostly solved with a sheet of PEI. The main issue now is eventual separation of layers once it gets halfway up or so.
I am using the Solidoodle filament with a bed temp of 105 degrees,extrusion at 230 degrees, 0.90 extrusion multiplier, and layer height 0.3mm. My software is Simplify3D. The lid of my printer is open, to avoid jamming the extruder. I have the basic out of box mods (missing screws, remove plastic covering over extruder, reverse fan, etc.).
Can anyone suggest what I should do to eliminate the layer separation?
