Hi, I have printed 2 marvin prints and both have same error I have used different settings in cura each time.
1. the right eye is bigger then the left
2. the left ear is deformed
3. bad layer adhesion on the back of the figure
My cura setting are atm: shell 0.8 bottom/top 0.6 density 20%, layer thickness 0.1, speed 50
Also tried printing with slicer but results even worse. I have a duplicator i3 v2
Any suggestions are welcome

What is your nozzle size? Sometime a bigger layer height 0.2 works better

In looking at it I would say you should check your print temperature. The eye and ear issues both look like the plastic is coming out too hot and so drooping before it can cool enough to stay rigid. If you are printing with PLA try adding an a fan for active cooling on the extrude as the plastic comes out, and lower you print bed heat to something like 45 degrees (if you are using it.)

Have you tried printing Marvin with different orientation ?
Seems like you have a fan only on the right side of your extruder, try printing Marvin facing it

TEMP LOW .REPLACE PTFE COUPLER AND USE FANS AT 20-50% IF ABS . IF PLA THEN FANS FULL BLAST

definitely orientation - spin it round to face the fan - that is what fixed mine (and dropping the temp to the lowest that the filament will print at.

Agreed. although you can get a better fan shroud off youmagine or thingiverse

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.

What temps and speed are you extruding at?
Dear Friend,
Send me your STL file, I can help to print it and show you .

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.

temp 185, fan 100%, speed 40

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.

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!

Checked the temp and it is fluctuating 3-4c, seems to be a wekaness on the wanhao i3 v2, alot of people have same issue. Found a fix for it and will do it this weekend along with some other upgrades.

Thank you all for your suggeestions, I will do some upgrades on wanhao and tune some setttings, will post new pic`s of marvin once done.
