Round post help

[precisionpete]

Trying to make a simple toothbrush holder that uses a center post.
I have tried changing quite a few things and the post never seems to print round or straight.
PLA on painters tape
Previous settings Layer .4mm
Print speed kinda high 80mm/s
Infill .1
Bed temp 60/ extruder 205
For these pictures below settings:
extruder changed 200
layer .1mm
print speed 30mm/s
infill .1
2 things I noticed different with these settings one layer on the base came apart and the crosshatch pattern is see through where the top settings these 2 things do not occur.
My post is still the issue, not straight or round.
Using Slic3r with orion
Thanks for any tips,
Pete

I would try dropping the speed down very low for such a small piece out of PLA. It looks like the tower is just too soft to make a nice tower. Even 5mm/s for the tower part wouldn't be bad.

On these pics it looks like you have some serious underextrusion. Have you calibrated your e-steps? It will all fail pretty bad unless the e-steps are set up nicely

Your clearly under extruding, but that's not the issue with the tower.
Printing towers like that from PLA is quite tricky, you need to slow way down (Set the minimum layer time in the slicer to the 10s range), get a lot of cooling on the part (Squirrel cage fans rock in this regard) and drop the hotend temperature as low as you can reliably still extrude. What you're trying to do is give the plastic from the previous layer time to cool before printing on top of it.
The other thing you can do that helps is to print 2 or 3 of them at the same time, this gives the plastic time to cool as the other parts are being printed.
