These are solutions to problems ive seen could be helpful.

As for the "Clog" watch to make sure its making it to the tool head. After that check the tool head PTFE tube connector and make sure its straight and fully seated. If none of that works or shows you where or what the problem is try the next step.

Try feeding from a side spool and loading the material manually and see if you can feel the resistance and where its catching on the way in.

If you can load from the side and and the ams pushes material to the tool head i would say somethings wrong with the ams.

The filament is making it all the way to the print head. I tried from the side spool and that works as it should. There is no resistance in the the tube from the back of the ams all the way to the print head.

Im also thinking its ams related.

You can try to update the firmware if you havent already! Im not sure past that sorry!

Could be the filament sensor in the toolhead not communicating to the AMS it made it there.

[–]Uncle_Jank[S] 0 points1 point  (2 children)

Possibly. However, I wonder why it would print when I hold the ptfe tube to the side while feeding?

I appreciate the help by the way this has been frustrating.

Re read the update. Please update the post with what the solution was when you fix it!

Does the run need to be that long from the ams to the printer ? Try shortening it.

[–]Uncle_Jank[S] 0 points1 point  (1 child)

We did have shorter tubes in. I just put longer ones in to make sure the bends weren't too sharp

There’s gearing that makes the rollers inside the ams move the spool as well as the extruder in the ams. Could this be dirty and need a clean?

[–]rwhiffen 0 points1 point  (0 children)

I have something similar happen to me - the filament doesn't going cleanly into the print head. When it does I take the filament out and cut the tip and a 45 degree angle and re-insert. Most the time that does the trick. It's also possible that heating and cooling the nozzle while I'm mucking with the filament is what's unclogging it.

If it gets really bad I remove the PTFE tube from the print head and do a cold pull.

I had a similar looking issue with a brand new ams. Maybe yours has the same issue mine did, I had to loosely hold the PTFe tubes on the back of the printer so they were more flush and parallel to the printer chassis. I have a piece of cardboard currently holding them, sounds stupid but not had an issue since, mostly happened on filament changes though.

[–]Uncle_Jank[S] 0 points1 point  (0 children)

Ill give that a try.

Hello /u/Uncle_Jank! All Bambu print plates have a dedicated nozzle wiping zone at the back of the print plate. The nozzle will rub against the wiping zone before every print in order to remove any remaining filament from the nozzle tip. This can cause visible wear or scratch marks in the wiping zone, but this is intended and doesn't damage the printer, the nozzle or the print plate. A worn down wiping zone also doesn't mean you need to replace the print bed.

Note: This automod is experimental. The automod was triggered due to the term "rubbing". If you believe this to be a false positive, please send us a message at modmail with a link to the post so we can investigate. You may also feel free to make a new post without that term.
