Random Unexplained Quirks with X1C

Can anyone shed light on these issues and perhaps recommend a fix? I am using default slicer profiles 190 -200 c and Bambu Matte PLA filament and have had a number of successful prints already, but these quirks are getting really annoying.

  • localization marker not found with a genuine Bambu Labs Engineering plate - I just tap resume - BUT what is causing this occur randomly?

  • the occasional filament strand stuck to nozzle when performing bed leveling and i noticed if I left it on until after I can get a chance to clean it off - it just throws off measurements and I usually get a spaghetti mess - so I just stop the print and start over

  • Using 1 out of 3 AMS units (no mods) - so far I noticed this on 1 unit - multiple random - "Failed to pull out the filament” messages when just starting or changing colors - I checked the spools and they are seated correctly and don’t appeared to be tangled - I assume there is a sensor that trips when pulling and if i is too tight it sets it off - I DON’T TOUCH A THING - all I do is hit retry and it works no problem.

Overall I am liking the printer more than I did, but these unexplained quirks really can get frustrating.

Thanks
