My printer cannot print in 0.08 layer height

I am having trouble while printing on my Bambu lab p1p, whenever I get it to print in 0.08 layer height after a couple of layers the print comes off the bed and the print fails, I have had the printer since june this year and have been having these troubles since about 1-2 weeks ago. Can anyone help?

The safest minimum height of the layers is generally 0.25 x width of the nozzle. Below this height, the quality becomes unreliable. My X1C still prints 0.8 mm high layers, but worse than 0.1 mm high layers. 0.25 x 0.4 mm = 0.1 mm.

With a 0.3 mm diameter nozzle: 0.25 x 0.3 mm = 0.075 mm. A layer height of 0.8 mm would actually require a nozzle with a diameter of 0.3 mm.

However, this has little to do with your problem if the layers are heavily compacted. Here, the problem is usually a first layer that is too compressed. This compression of the filament then continues in the layers above. In this case, however, the print would also be difficult to remove from the printing plate, but this again depends on the plate used. You can also measure the total height of the printed object. If this is too low by 0.1 to 0.4 mm, this could also be an indication that the first layer was pressed too hard.

From a distance, it is difficult to tell exactly what your problem is with the printer. Therefore, I would write to BambuLab support and ask them once.

You may simply need to set the offset of the nozzle a bit higher when calibrating at the beginning of the print.

Have a nice day!

What is your first layer height? Is it the standard ultra fine setting? I have not had any problems using their settings, but I would see if you can increase the first layer height.
On top of my head, BBL uses 0.2mm as the first layer height for that profile, and it worked out flawless for me. Never had any problems.

Did it work before? Have you checked if your nozzle is worn? What about the bed? Which one are you using, when and how did you clean it?
