z banding

Z banding is usually a mechanical issue in the Z axis such as a bent guide or bent screw. Not sure what you are calling z banding in those samples though. If anything the lines look over extruded to me and maybe not hot enough. They are all too round and pronounced.

Over extrusion is caused by poor calibration. Your extruder steps per mm should be calibrated properly. Otherwise when you ask for B amount of filament you may be getting C amount instead B amount.

Under extrusion can be cause by low temp but over extrusion is caused by poor calibration or incorrect slicer settings not having to do with temp.

Z banding is not a shift but instead bands that appear at regular intervals along the z axis of your print. In your image I assume you are talking about the place just above the letters. That is not Z banding since it only happens at that location.

The anomaly in your image can be a caused by a mechanical issue or an electrical issue. You could have a bad wire that is stressed at that point in the print and looses connection. It could even be a bad file. Do all prints have this anomaly or just this one?

The image below exhibits banding. Two of the same objects. Normal on bottom and banding on top. Notice as I said the banding repeats at regular intervals.

Ok, so i made my own 25mm solid block, and I do not get that issue, however, i get a different issue haha. Notice on the bottom edge, the extrisuon, as it finishes, is super thick and overlaps the other shell. All 3 faces of the block are smooth except the one with the overlap, its jagged all the way up. Thanks for looking. Could be my filament, could be something else.

Forgive, sometimes i just forget to add those basic things. I tell you, thermodynamics is a brain killer class.

here are my settings from xyzprint software:

Awesome!! i will try that later today when i am home from work:)

Thank you much for the advice and help. Ill update with pics.

Ok, so after trying to set extrusion ration to 98%, first layer height to 0.30. the print comes out the same. Onall 3 prints with different settings, its only that one side with the issue. the opposite is even, no embossing or overhang. the other two sides are smooth as well.

I am using the hatchbox grey filament. not the xyz stuff.

I still think its over extruding. Or its the mere fact that this is a 200$ printer. Hence why i am saving money for a new folgertech i3 or ft5r2

thanks

EDIT:

not sure if i mentioned this but the printer is 3-4 years of age and its the original nozzle..

ok, here is the file. thanks again:) I am using teh stock software. I have not branched out to anything else yet until i get the ft5 or i3, which i am way excited for. hopefully 6 months or less i will have one of those two

My printer went down. i just got the parts to repair it and will work on it this weekend. I will try your stl once I get my machine up and running.

Print one of these: https://www.thingiverse.com/thing:1724209
And one of these: https://www.thingiverse.com/thing:839620

Buy one of these (Bowden, 12v): https://e3d-online.com/lite6-hotend
Or preferably one of these (Bowden, 12v): https://e3d-online.com/v6-all-metal-hotend

You can wire up the new hotend to the wires where the old ones were, and you will be back up and running. The circuit board will need to be moved somewhere else, but that shouldn't be too difficult as long as everything still wires up the same.

After you do this setup, you can replace just the nozzle if it wears out again.
