I’m having trouble with a somewhat large print. it’s an optical bench breadboard that has a bunch of holes in it. I get great adhesion for the perimeter but when it starts to print the hole perimeters, they don’t stick. It looks like what’s happening is that when it moves between holes, since it’s not retracting, it’s dragging a bit of filament with it across the perimeter of the holes and basically knocks the hole perimeter off of their spots.
Here’s a video of the process as well: https://photos.app.goo.gl/ESXAYG16dg2DUL1U8
I’m using a TAZ 5 upgraded with an Aerostruder and the modular print surface/PEI.
Filament is PolyLite PLA with the default settings (205/60)
I have tried it with a clean bed as well as with a layer of PVA glue. As I said, I get excellent adhesion of the skirt and external perimeter but once it starts printing the holes, it’s a mess. Is there a setting I can change to make this work?
