Thanks for the input.
I''ve recalibrated e-steps took your suggestion and came up with the comparison print. Now, it seems better but i dont think it should still be looking like this right? Also there is still evident issue to the RIGHT side of the print(where the thumb is), lines are BIG.
I actually have a big table fan blowing towards my print, so i dont think this is cooling issue; besides im printing at a slow 15mm/s.2 walls, 0.5 layer height sliced with CURA.
Any other suggestions? Do you see a difference? is it better?
I took a video but cannot upload here, there seems to be a size limit. Where can i show?
Thanks alot in advance

Your still over extruded. What are your current esteps?
Print about 10 layers and drop your esteps by 10% using eeprom. Let it go about 10 more layers and drop again. Keep doing this until you start getting spotty deposition. You may have to drop it down quite a bit. Use the estep value that looks the best.
Your parts look very nice dimensionally. If you do have an issue with your z axis it will be easier to diagnose when the esteps are tuned

Current step is 140. i tried to go lower around 130 but my wall thickness becomes .3815 instead of .40xx. Shouldnt my objective be getting shell thickness as precise as possible? Also, when i go lower, i have one side of square not connecting with each other. i dont have the part now but ill try to show you next post.

Is your X carriage supported only by the threaded rods and nothing else?
Unless the threaded rods are *perfectly* straight you're bound to see some banding, especially at lower layer heights.
Some printers use smooth rods or linear rail to guide the X carriage up and down the Z axis. The threaded rods only provide vertical movement so that type of banding isn't as much of an issue (it can still happen, though).

You post 10 pictures of bad prints but not a picture of the printer. I googled your printer and there are like 10 different configurations and none of the pictures are any good. Post pictures of your printer...the whole thing...and a few of the Z axis lead screws and Z axis smooth rods.

Hi, im out of town right now so i dont have my printer with me and cannot take pictures of it.
I do have smooth rods not just threaded rods holding up my carriage. It is actually my bed that is moving up and down on the Z-axis.
I have attached another print. I can see improvements especially on the lower part of the print(am i right?). but when it gets higher...you can see the "banding lines", How is this so??
