I just got my Bambu Lab X1 Carbon yesterday and already did 8+ Prints on it with PLA and PETG.
I noticed that on the build plate there is a section where the nozzle seems to be resting and melting the coating until the metal shines through.
I didn’t find anything regarding this specific issue and wanted to ask if thats a problem or if everyone is experiencing this the exact same as I use the default settings most of the time.
Oh, thanks for the information. I haven’t ordered the high temp plate / sticker yet, nor have I looked it up on the store site.
To me, it also seems to wear out a bit quickly after just one day (~15 hours of printing). But I have only found it at this point, so I am fine with it as it seems to be intentional.
Yes, without any problems so far. I only changed it for one petg-cf print to the engineering plate but didn’t touch the high temperature plate setting.
But it seems that it’s only affecting the hotbed temperature and not any of the nozzle setting as far as I found informations online. I think I’ll contact bambu lab to be certain that this won’t cause any problems in the future, especially for the nozzle
If you look in the Bambu Lab store, all the build plates include the following quote:
Before auto-leveling, it is necessary to repeatedly rub the nozzle in the special wiping area of the build plate to completely remove any residual material at the tip of the nozzle. The coating in the special-designed wiping area will gradually become worn over time. This is normal and does not affect print quality or nozzle lifetime, so there is no need to worry about any quality issues
This is completely expected and by design. When performing bed leveling, the tip of the nozzle is repeatedly wiped on the trapezoidal tab on the back of the plate dedicated for this purpose. This is to ensure that there is no buildup on the nozzle that could throw off the piezoelectric ABL which is a pressure reading of the nozzle touching the plate. Any plate with a coating will quickly rub the coating off. The nozzle just rubs on the bare steel with the coating out of the way.
Yep, the slot between the tab and the main plate surface is there to let the wipe area flex a bit. I’m guessing it helps by providing enough compliance to prevent the head from moving the plate around and/or to decrease pressure between the nozzle and plate to avoid premature wear.
is the following process done automaticly?
repeatedly rub the nozzle in the special wiping area of the build plate to completely remove any residual material at the tip of the nozzle
Coating on that area is a consequence of coating the whole plate. Intended operation mode is nozzle rubbing against bare metal. Likely they figured out they can simplify manufacturing process by not removing the coating. I’ve seen some photos with that area not coated. Looks like early units considering filament types printed on it.
