Banding/Wobble/Layer Shift

Sorry, and this is PLA

Yes I did. Hmm. Doesn't look likes it's changed much.

could anything else be adding extra vibration ?
noisy cooling fan for example ?
Also clean ALL the rods. Not just the z-screw itself but the guide rods as well.
basically when I do a clean (one is due) I wipe down every guide rod and the screw.
You can actually hear the difference in the sound the printer makes afterwards.

Your settings look fine, what make is the pla ? And is this the same roll that worked fine before the problem started ?

Not that I know of. There is an extra cooling fan I have but It was there and on before this started giving me issues so I doubt its that.

Yes I cleaned and oiled all the rods.

Speaking with the manufacturer hes telling me to check the bed screws and the screws holding the z motor. Checked all screws and all were tight, although I was able to tighten the zmotor screws a couple more turns.

Told him that and hes saying he thinks its still a loose screw somewhere. Idk what else to check.

The metal bracket holding the bed doesn't look bent to you does it? looks kind of slanted to me \ but barely. wonder if that has anything to do with it with unable to slide down the guide rods smoothly. I don't really feel anything though. Idk

Just in case if you haven't already - check out this for banding.

Thanks yea I use that guide habitually.

Is the part sitting square to the bed? In other words are the side walls of the part parallel to the sides of the bed? If so try rotating the part at an angle so your x & y are not absolute.

Yes it is. Trying a print now. So well see if it helps printing it at 45 degrees. Still would like to know what caused it though. My prints were never perfect, but this started happening and getting worse and worse. Has gotten a little, very little better since cleaning and oiling rods.

Lets see how that works. I am spitballing but if you look into the sailfish firmware manual (way learning this myself) the acceleration deceleration is more than likely the culprit. The head doesn't know how far it needs to decell to print the next layer.

Again full of speculation but the lubrication reccomended might be a clue to extra resistance


Tilting the model makes the x & y work together rather than one or the other. Might.... may.... give you insite into what is going on.

That being said it maybe belt tension. These printers are not great at addressing that.
