Weird tails and zits on sidewalls

[New printer guy, 3 months roughly]

So I had an issue a while back and this started the whole issue i think but its weirdly intermittent. The issue was when homing the z axis it was go all the way to the top and then start making a clacking noise as if trying to go higher up. I stopped it immediately, tried again to home and calibrate and it did the same issue. I restarted the printer and it calibrated fine.

Currently at work sending this from my phone. I will get more detailed info if needed.(I am sure it is)

Issue I am having now are these weird tails and it drags on the infill some times. The tails happen on any filament, im sure the zits and bumps are the moisture from the filament not being dry, I am working on that.

The new update is also around the same time these tails have happened.
The settings for the filament have been the standard preferred setting from bambulab filament. I am just hoping for maybe some one has the same issue or has seen similar. The learning curve for this has been amazingly fun, just need some peers and their opinions now.

Thank you for anyone reading this and taking the time for helping.

I had a same problem with my A1, have you found the solution?

I had just found the solution by formatting your SD card on A1, or replace with a better quality card will totally fix this. This is just because of the reading issue that cause momentary pause, just remember to format your card 1/2 months and keep the storage below 20gb you will be fine.

I will try this and if it works I will write here so other people know that the issue is caused by this.
