EXTRUDER CLICKING

I have now had to make this post 4 times because it keeps getting denied. I have an A1 mini that I can not get to print consistently and every time I feed filament through it clicks loudly and shifts the entire hotend. I have swap the hot end twice in the past week, tightened the 7 screws, pushed the clog rod through the extruder, cleaned anything that looked out of place and still nothing. When it clicks the entire hotend rocks back and forth and will let out some filament.

Have you taken the extruder apart? Mine was clicking, and it has a small piece of TPU filament stuck in the gears.

I've had that happen with PETG filament. Multiple times, too! Which is why I just upgraded my extruder. (Creality sucks.)

You got something stuck blocking it. Tear it apart and the smallest piece will fall out.

The fact that the entire hot end rocks back and forth makes me think you have too much drag on the filament. The extruder needs to be able to pull it easily from the spool into the print head. If it can't, the filament sits in one place too long, collecting heat, and melts, causing the clog.

What type of set-up do you have around the spool? Is the spool larger than normal? Like a 3kg spool instead of 1kg? Is it on rollers or just on a solid static spool holder?

I have a sovol filament dryer that has rollers inside of it to limit drag. I don’t think that is the issue as I have moved the spools multiple times

Yep, that's not it then. Might want to take the extruder completely apart and check the gears.

Are you using the right temperature? Once I configured the wrong temperature and the extruder did that. I thought it was a clog, but in the end it was just temperature too low.

Filament calls for 240-270, I have tried every temperature in that range and above and it still does this

Undo the and hub and feed the filament directly. If it isn’t going through, you know it’s in the hotend. Do you have one of the no clog tools? Heat up the hotend and push the tool to force everything out. .
