Bambu A1 prints all of a sudden not sticking to plate anymore. This morning same model worked fine, now filament not sticking. Same roll, PLA basic black. Washed/scrubbed the plate twice. Flipped the plate. Checked for clogs. I’m at a loss and would love some pointers.
Is the plate type set correctly in Bambu Studio?

How are you cleaning your plate?
Cleaned the plate twice, no difference.
Have checked the plate setting, yes.
Apologies if my question is unclear, how are you cleaning it, not are you cleaning it.

I wonder if you could have loose internal toolhead screws. Jon will have the link handy, it’s not in front of me now.
Ah, was cleaning it exactly following the guide 
I’ll check the screws, think I checked them when I got the printer.
Sounds like the infamous varying nozzle height problem. Had that with the work A1, but in reverse as the nozzle was far too low, so I had to alter the gcode to lift it up. You can also lower it the same way.
This is how I solved the problem. That started about two months ago, then about two weeks ago i had to start gradually lowering the nozzle with it ending up back at standard height again.
Absolutely no idea why all that happened.

Thank you, how would I go about trying that? Sorry, complete newbie here.
It’s also going from bad to worse.
Last try the nozzle seems to really hit the plate pretty bad 
, horrible noise as well
After removing the print you can see it edged in the plate
Trying a factory reset now.
After a factory reset, I think it was trying to clean the nozzle? It was literally moving into the plate, scratching it very, very badly.
I’m really worried my new printer is broken
It’s difficult to find if you don’t know, but quite easy once you know how.
Hopefully the images show up in order -
- First go to the top-left of the slicer prepare page. Click on the edit icon to the right of the 'Bambu Lab A1 0.4 Nozzle option.
- That’ll open the window where you can alter the various settings, and so you click on the ‘machine gcode’ tab.
- Scroll down to near the bottom of the ‘Machine start gcode’ window and look for the highlighted line. Where it says {-0.2} you can change that to whatever you need. From the looks of your manged plate I’d start off with something like {+0.30} and see how that goes. I’d recommend naming each one with the nozzle offset so you can keep track of them.
- If the first layer doesn’t stick then take it down by about 0.02 mm at a time.
Lemme know how it goes!
Thank you so much!
Weird thing though, everything was working perfectly again last night.
I tightened the screws behind the nozzle, did a factory reset, unclogged the nozzle 3 times and now…perfect prints again (and 1 ruined textured plate).
Weird stuff.
Well it’s fixed, that’s the main thing.
A factory reset is good for fixing these weird anomalies where the print head isn’t where the printer thinks it is. If you’re up for it I would still open a ticket and send them pictures of the scratches on the build plate to see if they would replace it.

Thanks, I absolutely made a ticket for this.
Also just really happy I’ve not bought a paperweight and it’s printing normally again.
