Ripples and peeling in large flat areas
Hello! I have had my mini for about 4.5 years at this point and recently moved with it, which involved packing it into a truck and driving several hundred miles. Since unpacking it, I have re-lubricated the X and Y bearings, checked belt tension, made sure that the X axis is square, etc, basically all of the "regular tune up" things. Despite this, I have noticed this ripple pattern forming on many of my prints which involve large flat areas (see attached image). It is inconsistent which layer it occurs on, this is on the second layer after an essentially perfect first layer, but it also sometimes happens on the first layer or on top surfaces. I've tested with ABS, PLA, and PETG and it does happen with all of them but seems particularly bad with PLA. I have also been using default slicer settings since I noticed this in an effort to decrease it but it doesn't really seem to do much. Sometimes the printer can continue, and sometimes it gets caught on the roughness and the print is ruined. I have not had much luck finding similar things online but I might just not know the correct search terms, so I am hoping that someone else might be able to help me here. I would be more than happy to provide more information as relevant, I just didn't want to overcrowd the original post.
Thank you so much!
RE: Ripples and peeling in large flat areas
Check if the cables to the thermistor and tye heater in the print head are not jammed by the plastic and the fan - because of that I had some temperature fluctuations when printer head was moving ( but did not happen when was not).
Check the nozzle for the clogs ( do some cold pulls), because you may get dust on the filament roll that got into the nozzle due to the transport/relocation.
Check if your filament path is not experiencing noticeable blockage, which would make it hard to insert/remove from the tubes or move along the tubes - extruder may have an issue in pushing it and thus it would end in uneven extrusion and grinding filament in certain places - if you unload it then it will have some parts of the filament damaged, if it works properly then it should have even rivets all along the line.
Check if you haven't damaged the nozzle tip - try with another nozzle or look at the tip inder the zooming glass.
Check if the nozzle itself is not wobbling or if the x axis is not twisted tobe bed ( though that usually manifests in uneven extrusion in ine direction).
