I print a lot of personal vaporizer prototype pieces for myself and friends. I have previously printed these pieces multiple times with success, now, same file, same settings, im having a weird issue.. doesn't matter what filament brand I use.. once it reaches the "taper", the nozzle literally smushes around, bending a good amount of the previous layers downward as it moves. But with that being said, it doesn't look like the first layer is smushed enough to the bed like before.. not sure..

- I double checked Calibration and found that only my steps per MM were off for my Extruder. (Fixed that, still no difference)
- I have printed a test cube and checked wall thickness. Everything is good, but it comes out .24mm~ taller than the sides.
- I have tried almost every combination of speed/Ext temp imagineable.
- I have Leveled the HPB over and over.

The pieces pictured below were printed at:
Layer Height: .2mm
First layer height: .3mm
Infill: 13% rectilinear
No support or raft (only bare kapton tape)
Speed: 40mm/s (first layer 25%)
EXT Temp: 225c (230c for first layer)
Bed Temp: 100c (110c for first layer)

Running out of ideas here... So any constructive input is welcomed!

Last note: These pieces were printed upside down so the "taper" is an overhang rather than facing up.

I don't even know how to explain this issue.

Thank you for your time!
