When I am printing objects that have a lot of surface area on the first layer parts of that layer will rise up causing there to be gaps in the first layer. Here are two pictures. The first one was printing with a raft and the second one was without a raft. I am printing on 3M Painters tape, extruder temperature at 200, bed temperature at 60. I am using Hatchbox PLA Filiment.
- Too far from the surface for the first layer. Filament doesn't look flat enough
- Possible slight under-extrusion (should be verified after fixing first issue)
