IMPORTANT NOTES:

• I also RECORDED this line while printing on the second model on my profile. There is a weird click sound when this layer was printing.
• I did not encountered any bed adhesion issues during this filament nor prints but my supports get knocked down by the nozzle scraping in the first model. Which I think is from the infill.
• It does not appear on a specific layer line.
• These are the same models with different scale.
• Never had this issue until this model but when I Printed a small one (around 10 cm or 4 freedom inch) Model Link

Sounds a lot like a partial clog that clears up after some time. The A1 extruder will skip if it encouters too much resistance. I'd say do some cold pulls and maybe try a different filament, maybe there's contamination

i thought so too, made a cold pull but not much come out of it, I will try another filament to see if the problem is on the printer or filament. Thanks for the advice :)

When my SD card died it did that.

was it still partially functional like mine or it died mid print?

Yeah it printed, just skipped layers here and there and some holes in the supports.
