A1 pause at the back corner?

My very first print with TPU and all the stringing, but that’s not what my question is about. Although if someone has some good A1 settings for cheap amazon tpu I would appreciate them.

This pic provides an example of something I’ve been curious about since I got this printer. The the stringing to the back corner? This happens several times during each print, I’m rarely ever in the same building as the printer but I think it happens during every print, even when not using the AMS.

The A1 will stop printing and move to the back corner. Sometimes it comes right back and resumes, which is ok? What ever. But sometimes it moves back there and just sits for minute or two, does nothing, which I find quite annoying.

Why does it do this? Is this normal A1 behavior?

It’s either the nozzle clump detection or the time-lapse functionality.

I don’t ever use the time lapse so I assume nozzle clumping. This printer does tend to give me the “filament on the nozzle or improperly installed build plate” error if I don’t get the plate just exactly centered. If more of the plastic underneath the plate shows on one side than the other it stops the print every time so I have to be extremely careful when replacing it. I think I may turn that “feature” off.

Thanks for the help.

No problem! I got a kick out of your avatar and name. If you post here Jon can change “user_3506673171” to that too, I’m pretty sure it’s not taken lol.

Thank you for taking the time to do this for me, I did find a method in the Handy app but when posting the old user still showed, that should not happen now

Thanks for the tip. I was wondering why it didn’t change when I entered the name.

Mine does that sometimes (moving to the corner of the bed), always on layer 2 (I think) so it seems normal.

Also for tpu, I don’t know what brand you bought but I used creality 95a and dried it first, there was none of that stringing. When using generic tpu setting in bambu studio.

Turns out the problem either is NOT Nozzle Clumping Detection or the ability to turn it off has been taken away from the users.

At this point it detects an error on EVERY PRINT, even though I have Nozzle Clumping Detection turned OFF!

This sensor going bad is yet another piece of the printer to fail in just 3 MONTHS.

Thank You for screwing us Bambu Lab. Hope you go bankrupt.
