Please help me

Oh sorry hear having issues with bed being warped =(. I must misunderstood what you were talking about prior on the thread.

You clearly didn’t read the issue. Yes your correct tapping 2-3 times in the same spot is normal. Tapping 30 times on and off, pausing then tapping some more then stoping all together and throwing an error code is not “nothing uncommon”

Yeah I see what I did now. I got this confused with another thread I read and got two confused =( Sorry about that man.

Hey you Guys,

the Support answered me:
They confirmed that the piezo sensors have problems with higher temperatures (the sensitivity decreases) and they are working on a fix.

it’s something… i guess

So it’s a concatenation of problems:

  1. higher temperatures will bend the bed a little bit more
  2. the actual sensor values, compared to the old ones, are too different
    3.the sensor sensitivity is lower

Thank you for sharing the support answer.
For me, it is still unclear. I can understand that the sensor’s sensitivity decreases with temperature. Yet, this will pose no issue if the sensitivity at high temperatures is sufficient. If not, this is a design problem; we should notice these problems from day one. At least mine seems to be working fine.

If the issues start later, the sensor’s sensitivity degrades at high temperatures, which worries me since this is my daily use. In this case, the fixes are replacing it with a sensor able to operate at higher temperatures or redesigning the sensor location, insulation, etc., to ensure that it is not affected by the print temperature.
In each case, I’m not convinced we must wait for a solution. Or if that is the case, BL should send spares so we can replace them when necessary.
Or am I misinterpreting this?

Hey you Guys,

in addition to this post, i’ve written an other with more informations and a test series with the bed leveling process:
Bed Leveling Process

I wanted to know if some other guys have the same phenomenon like me and harryson2101.

until now this post doesn’t get noticed too much…

so, now to your considerations:
I think it could be like the typical Bambu bed warping problem:
the early piezo sensors from the kickstarter time were perfect,
then they had to get a new supplier to satisfy the demand,
and this supplier delivers x% bad sensors.

it would be nice if you could read the other post and tell us if you could see the “three areas” on your bed as well. if not: I think you can be a little less worried about the quality of your sensors.

in the mean time I also managed to get less the problem (that the leveling process fails a lot).

I don’t know exactly what of the things helped, but here is what I’ve done in the last time:

  1. disassembled and reassembled the nozzle
  2. disassembled , cleaned and reassembled the extruder
  3. trimmed the bed (at the lowest temperature I wanted to print (55 deg cel))
  4. loaded the factory reset data again

it seems a bit logical that everybody, who has the problem, should check the nozzle screws and the extruder (inclusive screws). because the extruder is assembled to the print head, and the nozzle to the extruder. there could be some mechanical issues if the extruder or the nozzle is not as tight as it should be to get stable values to the piezo.

so I’ve printed about 10-15 prints (55/70/110 deg cel) and didn’t get the error, that the leveling process fails (wish me luck :-P)

but the higher the temperature, the more samples the nozzle takes on the “bad areas of the bed”

keep me up to date if someone had the same issues or solved the problem as well.

This video fixed my P1S, Thank you so much!
