Printing with Extrudr ASA… trying Cold Pull (Nozzle clogs | Bambu Lab Wiki), replace nozzle… and same problem… ¿extrusor problem?

Hello Mainmind,
It looks like a bridge is made then the problem happens for the next set of pillars on top of the bridge ?
What was all your settings ?
I don’t think it’s a bridge problem, the nozzle is clogged, even after changing it, could it be a problem with the extruder?
Is the printer or the AMS not able to detect that no filament is consumed?

O ok I understand now it will not print anymore 
Can you side load the filament into the extruder without the AMS ?
If it still will not feed form side loading the filament then check you extruder is not clogged.
with the nozzle unplugged, the extruder moves the filament, my question is if it can slip with the AMS not having enough force?
I have also changed the nozzle with which it comes as a spare…
The AMS is just a feeder and you have the buffer to help.
Now some people have had a interment AMS hub motors fail and it will not feed filament at times is this what you are experiencing on your AMS ?
Also if your nozzle was clogged you might have some filament build up in your AMS gear you will have to clean out.
I will try again clear nozzle…
I use 1.5mm x 300mm 304 stainless steel solid round rod to clean out my nozzles on all my printers.
Do you have one of these printed out ?
Hope you are up and running again soon

I had seen the original, I’ll have to print it first…

Thanks @3DTech
Same problem with 50% speed:
I think your overhang or bridge settings is what is causing your problem or retraction settings.
Also I would only print one at a time with ASA filament you have a lot of retractions going on with three parts at one time.
If these parts are for your AMS ? - PLA will work in it.

there are no wires… directly the nozzle is blocked, there is no excess filament, but lack of filament…
In previous weeks I have printed larger pieces, several small ones… although in another color but the same ASA material and manufacturer…
I will try with new nozzle and new profile, 260°C vs. 240°C from Extrudr:

ASA and with the Bambu Lab you need to run a temp tower using orca slicer you need these settings correct.
The color of the filament can need different specs you have to always tune each roll of filament.
Also when you have a lot of retractions going with not much filament flow it can start heat creping on the filament and also plug up your nozzle.

I try with profile of Extrudr with same result… finally after a lot of cold pulls… I break connector of interface board…

So… appear on Wiki but not possible to buy on online shop… waiting bambu support again…
Please @SirWill Ticket US230422924001 
O no 
When you get back up and running I would recommend Orca slicer and do some calibration and testing of you filaments

I thought I had been careful in the process, but not being careful once…
my intention was to clean one last time to print the tool

Thanks for your time! @3DTech
You can get a soldering iron and fix it or if you don’t have the tools maybe a local electrical tv repair shop can fix your board for you.

I also thought about it, but the soldering is very small, I still try to solder the connector externally…
I have received the replacement, I have been able to test with a new extruder and nozzles, with the same part and plate. Filament from the same manufacturer in black and white I have managed to print (this piece at 50% speed) but with the orange one it always ends up blocking the nozzle
NOTE: very interesting Orca Slicer calibration options Calibration · SoftFever/OrcaSlicer Wiki (github.com)

FYI: Filament color can have different influences when printing with them.
You will need to use different nozzle temp or retraction settings with the orange filament and also dry your filament before you start testing.
The Orca slicer will be the better option for testing.
