You've lost me...interface level? Where the print meets the bed?
Presume you're printing ABS?
No mate. Printing in PetG but using PLA as an interface because it does not stick to PetG and the supports come of clean. This however means you need a bigger purge tower and over 800% cleaning time. The model I am using has lots of places that could use support but the Auto support does not choose all places just some and I cant fathom why.
The biggest problem is I am getting heat creep and blocking when the AMS is changing filaments. Google is full of reasons and changes but brain fade is not nice
All of this was during high ambient temperature I could not lower/control due to weather. BUT its now doing it in normal ambient temps.
I am trying to find a decent video that shows how to delete supports I dont want.
That said I printed 3 of the 4 plates just fine, Its a base for Aerodry 2.0 part 4 has been a pain. Hard to confirm BUT I managed to print 3 and I actually printed 4 BUT it had contamination and the layers split easy..
I tried again and this time I had a blockage in the nozzle. I fitted a new nozzle and now it blocks everytime I try to print plate 4.
My reading last night indicated I need to try tweaking the printing temps closer to each other. Apparently the glass (something) is close .It would appear in my case using PetG for model and PLA for interface layers something is happening but I am not by the machine enough at the exact time the issue occurs. Google seems to suggest as I am using Petg the PETg is cooling and stopping the PLA from loading BUT I am not there to check whats stuck in the nozzle. It does not make sense to me anyway that the AMS is trying to load the PLA without the PetG retracting. which is may have done but .............and whilst thinking how to phrase this I have had a brain wave.
I was wondering what happens in the hot end. In a normal not end there is no retraction so the Knife in the Bambu is used before retraction. If my understanding is now correct the head with Petg is cooling all the time its going back to cut before loading PLA. So it is entirely possible the PETG has hardened enough to cause a blockage to stop the PLA loading. Again a BUT . I dont really know enough about what sensors and hardware etc are in the Hotend and how they operate, even though the last blockage jammed the Knife so I had to strip the Hot end completely.
I would make something but its not working ...Trying to find out exactly how it works. But Ai has gone potty again.

AI Overview
"
The Bambu Lab X1 Carbon's AMS (Automatic Material System) automates filament changing, but the process involves manual steps and printer actions. The AMS detects a required change and cuts the filament, which is then pushed out by the nozzle. You manually remove the old filament from the PTFE tube and insert the new filament. The printer then pulls in the new filament, performs a purge sequence to ensure proper flow and color consistency by extruding old filament, and resumes the print.

Not sure about Nozzles. Cant really tell nowerdays. But as for not printing it all in Petg thats because I have done loads that worked fine and I like to learn exactly WHY its not working now.
I appreciate that and I know that works as I printed some bits off to test. I really would like to get to the bottom of why its clogging.

I was asking as I seem to remember you posting about ordering them from amazon. I would order directly from bambulabs then you'll know they are genuine, which removes another potential problem with crap cheapo nozzles. I've had my printer for a while and have never had a blockage.
You could well be right. I got my nozzles from amazon. I have looked at Bambu so will get a couple and some knife blades.I was asking as I seem to remember you posting about ordering them from amazon.

I have only had two nozzles fitted since I had it.

It is a complete hotend. By comparison the standard bambu hotend is £14.
You don't just unscrew the nozzle like on an ender type printer.
