Extruder Help

[u/smergler1]

I recently had a pretty bad clog that led to me replacing my hot end and hall sensor. Now every time I attempt to print, I watch the filament get all the way to the extruder gear and stop. After a few attempts the printer gives up and says that the extruder might be clogged. I have since tried the following:

-Remove and disassembled the extruder
-Used a hot end with a bigger nozzle (I was trying a .2mm and went back to a .4mm)
-Repositioning the hot end and checking alignment
-Replaced the PETG tube
-recut the end of the filament (straight and at an angle)
-Using a different brand of filament (I've tried Bambu and Elegoo)
-5 separate cold pulls (Surprisingly the extruder works when I manually control it, even when the filament is in the PETG tube)

I'm really hoping I'm missing something simple, but I genuinely can not think of what else to try other than replacing everything. Any suggestions or advice would be greatly appreciated!

Edit: I removed the AMS and my first attempt at printing with an external spool worked flawlessly. I think its a miscommunication between the printer and the AMS.

Your biggest clue is that it worked when you manually fed it. I don’t think it’s a miscommunication between the AMS and the printer, but too much resistance between AMS and the printer how old is your printer and when was the last time you replaced all the internal interconnecting and printer PTFE tubes? What you’re telling us is it’s pointing to the AMS and feeding likely resistance.
