Going to name a few things some have been mentioned some not… But they are the same suggestions I give all i3 owners as well as many other printers.
- First off printing PLA you -NEED- a good blower fan setup on the i3 (look into this one it will be your achilles heel if you dont have the right setup)
- Im going to assume you got your heated bed running due to the wrinkly defects on the lower portion of the print. Your heatbed temps are too high… lower them as low as you get get them… 50C and under… lower the better (35-40C range is ideal, but if your leveling and bed prep is off it will be harder to keep stuck to the bed so consider those factors and possibly adjust those as well).
- Looks like your printing temp is -slightly- high… lower that about 5-10C see if this helps.

Suggestion
1.Try recalibrate so extruder is exact 1mm from heated bed
2. Print with support setting:touching bed.
3. Make sure extruder temp are in range
looks like printing too fast and z height is too high.
for a start try slowing it down to 25mm per second.
I get the same curling up on marvin’s rear end if I try to print him too fast and don’t allow the previous layers to cool.

0.4 nozzle, have tried printing at 0.1 layer and 0.2 height same result
Try 205c, 40 speed, 40-60c bed, fan 100% after 2nd layer. Are your temps fluctuating by more than 1-2c? How have you been storing your PLA? Ambient humidity? Would suggest trying to print something like 4 at a time to make sure the pieces cool before the next layer gets slapped on.
Make sure bed is covered in a light spray of hair spray for PLA if you want to print direct to the glass. Works flawlessly on my 4S.
Also may want to check out Jetguy on wanhao’s forums on google – fair warning, he’s a little irritable but he’s awesome too! Redirecting to Google Groups

A video or time lapse of this may also help…
Printing from SD not over USB right?
I had the same problem printing my first marvin with the back side layer adhesion. I tried it again with a slower speed and it worked fine, hope this helps!
