I have already cleaned the serrated pulley that feeds the filament into the extruder. Additionally, I tried printing without using AMS Lite and noticed a slight improvement. I also attempted to enhance the grip of the serrated pulley for a more consistent flow, but unfortunately, there was no change.
I have a similar problem; as soon as there is a change in the geometry during layer construction, these inconsistencies in the z-layers occur. For example, in the area of the whiskers on your cat. Unfortunately, I haven’t found a solution yet, so I’m also very interested in reading
The error on Z, on top to the whiskers of the cat is caused by an imprevist of printing, the printing did stop for a few minute and the layer was too cold for the restart. might be the same for you.
The print was actually runs through. I have this issue with all my parts with holes or geometric changes. Sorry, then I will open a new topic. Good luck finding a solution
This morning, I disassembled the extruder part to check whether the pulley was damaged, dirty, or had any other issues. Unfortunately or fortunately, I didn’t find any defects inside. Another possibility could be related to the motor , which might have a defect and therefore not perform the correct steps or other operations. Currently, I’ve observed significant overheating of the extruder motor, presumably ranging from 80°C to 90°C, at the end of a print.
Thinking about it, I have never lowered the printing speed so much, now I am trying to print the Bambu Studio cube, as I usually print at a speed of 200 mm/s, then I will try to lower it and see what comes out.
Although the cat print (first photo posted in this thread) is:
layer 0.16
outer wall speed 100
are you printing dry filament out of a filament dryer? fresh spools (no matter what brand) come wet out of factory. especially when they are on paper spools.
Hi, did you find the solution? Because I have a similar problem on almost one week old A1 printer. I printed the same model twice and the bands are in different places(there are a few common bands but mostly they are in other places).
I have a similar issue with my A1 mini that I’ve had for 3 days. I don’t know why this is happening either, it’s been happening ever since I received the printer.
