Extruder gear not turning

I’m on a P1P with a brand new stock extruder and hotend assembly which has never had filament in it. I can’t load filament since the gear wheel isn’t turning so I’m at a bit of a loss. I’ve been searching for info for three days but to no avail! I want to print! HELP!

I’m sure I won’t be able to help much but for a starting point are you using an external spool or an AMS? If AMS, it should feed automatically once you start the process and load once it need that filament for printing.

If you’re loading from an external spool, what steps are showing as complete in the checklist and which one is it stopping at? Here’s the wiki for loading an external spool - Load filament on spool holder - For P1 Series | Bambu Lab Wiki

Little more info. How do you know it’s not moving aside from filament not being extruded. What exactly have you done, etc.

There are a few reasons, but if you’d like help quickly the more details the better. I admit I wanted to reply “That’s unusual”…

The extruder and hotend hasn’t had filament in it yet. I see that the gear wheel isn’t turning. Could it be a short circuit?

I understand that. That isn’t anything that’s helpful.

Have you done anything at all? Did you bind it, are you using sd card to print from? Are you sending it from Bambu Studio?
Do you have an AMS.
Are you feeding from the external spool holder?
Are you getting an error on the screen?

See we can’t know what it is because all we know is it isn’t extruding.

When you select the screen option to tell it to load the filament, what does it say is happening? How far in the list does it go and which item does it stop on?

It’s binded, yes. It’s an external spool. All I’ve done is install the new accessories then remove the TPFE tube in order to insert the filament into the extruder directly after heating it. I was trying to load filament so no file sent from Orca.

I get an error message telling me to retry loading the filament. I can see that the wheel gear isn’t moving.

I’m questioning why the LED light doesn’t stay on now as it did before. Could that be indicative of a circuit blown? Perhaps that’s why the extruder gear isn’t turning?

If you’re using an external spool it should ask you if the filament extruded. Be sure that when it reaches full temperature and is ready that you advance the filament all the way until it stops so that you know it’s all the way up to the gear.

Following the steps from the wiki, at which step is it giving you the error. After you complete both parts of step 3 it should ask you if it purged rather than tell you if it did or not.

It seems to be a communication issue where the wheels turn when extruder is removed but not when it’s installed. Yes, the pins are securely installed in the ports.

I’ve watched many tutorials on loading filament and have tried all that were suggested. There appears to be a communication issue where the extruder is not talking to the printer. What to do about that?!

I’m not sure which PTFE tube you removed, but there’s no need to remove anything when loading filament.

From the back push manually the filament all the way to the extruder. When it stops you stop

On the screen choose load filament. It will then heat the nozzle to temp, move forward and perform a cut, then move back over the poop chute.

Once the nozzle is hot enough it will feed filament through the extruder to the nozzle. Unless you’re looking you won’t see much happening. When it’s fed it will give you the option of retry, all good, or nope.

You should be all good. From there load your print and go.

There is no short.

My daughter, a very smart and capable person fixed it by turning the plug around before inserting it. Wow! Thanks everyone!

Thanks, but I watch the filament come out of the nozzle to be sure it’s loaded. I appreciate all of the suggestions!

Sounds like he had one of the toolhead plugs inserted upside down, which can cause issues. Possible to do on the P1 series, but not on the X1.

I don’t know how you got that, but I’ll buy it. Pefectly plausable. Yep, why didn’t I think of that.

It’s very obscure. I don’t think of that either.
