Hello everyone,
After using my A1 printer for multiple prints and being very happy with the results, it suddenly started printing poorly.
First, I purged the extruder, but it’s completely clean. Even when it performs the filament purge at the start of a print, it seems to work fine.
Since my home has quite a bit of humidity, I suspected that the filament might be too moist. To address this, I dried it inside an X1C for 12 hours, following the recommended settings. However, after printing again, the result was terrible.
I have no idea why I’m getting so many small debris particles on the print bed or why the issue only appears at a certain height.
On other models I printed recently, I also noticed layer shifting or missing layers.
Does anyone have any suggestions on what might be causing this?
Thanks in advance for your help!
Estou com o mesmo problema! Vi que talvez fosse por causa do nivelamento, mas quando solicito o nivelamento automático está dando erro. Estou extremamente chateada com minhas peças e erros.
Have you tried a test print with different filament and did that alternate roll work?
If there are suddenly chunks being spit out after i know i dried it I would personally throw that roll in the garbage if it was me in my shop and consider something happened to it OR sometimes, in fact, halfway through some rolls it was company error and it turns to sh*t.
This literally just happened to me with MAX bone filament halfway through. I asked them for refund from the company with pictures as proof and binned the rest, I paid 45 bucks for it not cheap you know? Junk sometimes happens.
If all your filaments are doing chunks hmm then…nozzle blockage? something stuck in the hotend feeder? you have ams? something dirty whatever in the tube?
just throwing stuff against the wall here to try and troubleshoot.
@tamileskruger - Just to let you know people might not understand what you wrote in alt languages (He was saying the same thing is happening to him)
EDIT: on the A series it takes 15 seconds to swap a nozzle - if you happen to have an alternate one throw that on and see maybe?
The model with the magnets could be a different issue.
You appear to be using grid infil and a high percentage. Grid infill is a bit of a (bad word) because it causes the hot end to move over already printed lines, when you have a lot of infill, those cross points get taller and cause impacts.
Consider something like Gyroid (I prefer this).
The issue started at the insertion point of the magnets, are you sure the magnets are at least NO TALLER than the current print layer?
The “layer shift” is much more likely the impact with the magnet of the coincidentally identical location.

Unfortunately it happens with different filaments and different material Petg and Play too.
I have an AMS and it worked properly till now. What i recognize is that the at the beginning of each print the x axes(front back from the plate) is light shifted in front, like 2 mm or something like that can it be a reason? Any suggestion to also solve this problem?
I used grid infill because giroid is way to weak it doesn’t get the stiffnes i need.
I printed the same model on x1c and it works perfectly so i don’t think that are the magnets the problem, what surprize me is that the print after is quite smooth. See picture
I don’t also understand why so many smal filament pieces on the building plate.
The magnet will not explain the layer shift i had on the black big pla model. It doesn’t have magnet inside.
Thank you for dismissing good advice as irrelevant.
- Grid infill is known to cause problems, you have it at a high density, this increases the risk.
- I said I use the gyroid, I didn’t say you should.
- With the infill percentage you appear to have the model at, any infill would be perfectly strong, as would less infill and more walls.
I specifically stated I was only discussing the magnet version, so this comment was irrelevant.
As you can see.
This says you should be looking for something other than the filament.
Because it is impacting the print and those parts are coming off.
After a few layers, not impacting, things average out and smooth is the expected outcome.

I tryed to print one version without magnets and it seems to work well, not perfect but way better. so probably this was the main problem.
i try to lubrificate the Y axes and retight the x-y belt
i still have tought about printing big models but let see when i will do it.
Because it is impacting the print and those parts are coming off.
make sense, good to know thank you
Marco - this has gone on long enough.
He was politely berating you for totally ignoring the actual reason, you going back to your (bad) that doesn’t work, ignoring everything else he suggested and continuing to write 3 sentences referencing what you said originally.
When asking for help please try to read, and use, the solutions other members have taken the time to write or redesign AT OUR EXPENSE AND TIME as Malac did above.
While we are not required to help you, or anyone, annoying the people that do write and experiment to solve problems isn’t going to do you (or anyone) any good long run.
Go back to the top of your thread and re-read everything, I believe your answer is here in this thread already ok? 
i don’t understand why you take it so badly, i complete read ewerithing you write and thank you i learn new important thing, all what you say was just not the aswhere to my problem except the magnet(that was right and really usefull) thanks for that, i checked the nozel and the ams tube,
i have made many test prints, and tested all your advise the infill was not the problem, yes the wall thickness can help the stiffness of the model but i also need to add weight, and everithing make absolutely no sense with the big black model i tryed to print and had big layed shift, so i try to also think and not just expect you to make the yob for me but try to solve the problem also by myself.
if i didn’t comunicate properly or not enought my gratitude to your help and probably also i explain me not perfectly i excuse me for that but that was of course not my intention.
on top of this i’m not fluent im english and is difficult for me to explain myself and that for shure brings other misunderstanding.
You both seems to be very competent and ready to help so i hope in case i have another problem in the future, to recive answer for you because it will for shure help like it did this time.
what filament are you using exactly?
Originall Petg basic pink/violet from bambulab.
