Gaps in printing

Between the layers is space. Here is what we've done to try and correct the problem.
We've made sure the printer's calibrated, nozzle is not clogged, rerun the PID loops, played with extrusion width, cleared the hobbed gear. We did find the PTFE connector was bent. Replaced that and it's still happening. Any other ideas or suggestions you have are appreciated. Thanks!
Some details:
We are printing in Hatchbox PLA, white.
200C for hotend temp
bed temp is 60C.
E3d V6 hotend with volcano adaptor.
using a .08mm nozzle

With PLA it could be extruder drive motor getting hot and softening the PLA, limiting extrusion. Also might be the issues some seem to have putting PLA through a v6. Check that the hot end was assembled per instructions and retraction is short and slow. I use 2mm and 10mm/s on my v6.

Did you configure your slicer to account for a .8mm nozzle and a reasonable layer height? This looks like typical filament starving. With a nozzle that large, extrusion speed too high could also cause a problem. What happens when you slow printing down to 20mm/s?

Good point. My retraction settings are very different than that. I'll give that a shot.

Yes the slicer is accounting for an .8mm nozzle. Layer height is .2mm and the speed for the first layer is 15 mm/s. The rest of the print is at 30 mm/s.
