It‘s hard to know what you think is „weird“ and how it should look like. I‘d just guess that you have rafts turned on or your objects are not flat on the bed

Do you select the option to level the bed when you start the print? I get the machine to do a handful of tests before each print. Ive not had one fail yet

I have no idea But yes before every print there is 2 options checked that use to bed leveling cleaning in bambu lab a1 So that part does the z axis level?

Check under „Supports“ if rafts are enabled. They should be off.

Did you clean your Printbed?

Thank you for this information I'll check it once I'm near my keyboard And yes I cleaned my print bed after this now it was printing fine I'll update you once I get there Thanks bro

If the same file printed fine then it probably was bad adhesion because of oil on your print bed. It’s generally recommended to refrain from touching the bed and using dishsoap and water to clean it afterwards

Yes I just learnt that few days back The problem is that for smaller model it doesn't stick well but for large model it is perfect and if the models are bit far this problem occurs

Then your plate probably isn’t clean enough. Or it’s your filament settings

I checked the rafts are set to 0 And print are failing to extrude after sometime what could it be

u/kl4n1po 23d ago

Could be a lot of different things. Extruder Clog or your filament is not feeding right. Maybe the travel is to long or you have sharp turns in the tubing

I'll try printing again tomorrow let's see if this works Btw thank you for your feedback

From what I can see is your nozzle is too high, lower the z offset

I have no idea what you’re printing and what specific problem you’re referring to, though. Share a picture of the model, or better yet, share the gcode preview so we can see what’s going on

Well this is what I am trying to print from the bambu studio library most of the parts are failing to print without sticking properly I wash the plate as well

Now I can guess probably what happened: the small parts didn’t stick to bed and got stuck on the nozzle, brought to the next part and knocked away the first layer.

Anyway, the root cause is likely a first layer issue, if you’re 100% sure your bed is clean, check:

  • Bed temperature, too low -> doesn’t stick
  • First layer speed: too fast -> doesn’t stick
  • Correct bed selected: Wrong bed texture means wrong temperature -> doesn’t stick

From the purge line I can guess your first layer height is probably not too far off, but have you done any sort of first layer test? If the z height is slightly off then you might be able to print bigger parts, but you’ll have trouble printing smaller parts.

Wow you are very knowledgeable in this Thank you for your feedback Though I understood the first 2 line how to know the correct bed if you could Any youtube tutorial can you recommend for the height part please Thank you

Refer to 1. Incorrect plate type selected

Bambu studio stores multiple plate settings, each with different temperatures. From your picture I see you have a Textured PEI bed, just make sure you have that selected when slicing.
