A change not mentioned in the release notes - the Lidar AI features at the start of a print (checking the bed for leftover material, first layer check) are disabled if you are using the textured PEI sheet. (Flow calibration is still done.) There is no notice of this nor an option to do it anyway. Perhaps we’ll get some control over this in the future - I know Bambu has said that the Lidar and textured sheet don’t get along well but I never had a problem with it.
(if i’m not mistaken) LIDAR is supposedely failing silently, so you don’t know if it works or not (= with PEI, LIDAR step was executed, was (probably) always failing (without any visible warnings), and default values were then used). And this would explain a) why you never had any issues with it and with PEI (same for me, by the way) and b) probably why it is removed (was useless + once disabled, will speed up by ~20-30 seconds the beginning of the print)
Try power cycling the printer …
That’ll be difficult since I’m at work 
I’ll try later tonight
Long live smart plugs. Updating 
There is a good reason why we are not recommending using the LIDAR with the textured plate, and that’s incorrect results.
For example, you will get a badly calibrated K factor, and the print quality will suffer.
Even though the calibration is completed, the uneven surface of the plate can interfere with the measurements.
I strongly recommend not performing the flow calibration on a textured plate, to ensure good print results.
Understandable.
But is there a way we can see IF the flow calibration has failed?
Here’s why:
When I switch filament type (with vastly different flow caracteristics) I want to know if calibration failed because then I want to start again instead of wasting in some cases hundreds of grams of filament
I had a single print last week with very bad flow calibration (lots of gaps at the end of the infill lines) and would like to know if I can atribute the bad print quality to a failed flow calibration. (print on cool plate)
I would have loved to know if calibration failed because then I could have avoided having a 300g print with worse quality than the X1C can give me
Manual calibration should be implemented as in P1P, as an option for these cases
I forwarded your suggestion to our development team for their consideration in a future update.
But please note that the calibration might not necessarily fail. For example, instead of a K value of 0.025 you might get 0.015 because one section of the calibration line was not measured accurately due to the uneven surface of the PEI texture.
This doesn’t mean that the calibration failed, but it means that the measurement was not done on the recommended smooth surface.
This is also the reason why we don’t recommend calibration on the textured plate. Even though it seems to be working in some cases, the results are not always ideal.
@BrotherC, up 'till now if i want to use the textured plate, before i start the print i first do a small print on (for example) the cool plate where i also use the calibration. That way (i presume) the filament used is calibrated when i start the actual print on the textured plate where i skip the calibration. Well, only when the calibration values are still stored in memory.
In this new firmware, does the above workflow still work, in that the print (on the textured plate) is then calibrated?
For me a perfect solution would be if the K value would be visible after calibration (on smooth bed) so that we are able to transfer the value into the filament profile. That could solve the problem with PEI sheet and could also save time if we could avoid calibration for known filaments.
On my old printer I can modify my K value mid print. I used to hover over the first layers, adjusting the K value till corners and seams were spot on…
Now that would be a perfect solution, in addition t yours of course
Can you please please let us store/recall or at least display the calibration values for different filaments? At least then we could let if calibrate once on another plate and recall it for printing on PEI. I think making it part of the profile on AMS that could be displayed and edited would be more than sufficient for start. Thanks!
I noticed 
In fact I was astonished to see that working without updating or even restarting the Studio (running SoftFever actually), it just showed on the next print.
One thing I’m not clear on - is the “clean rods” and “lubricate rods” just calculated on print time, or is it actually something the printer detects from higher currents or something like that? The changelog talks about “detection” but I’m skeptical about this term
I think it’s just time-based.
Every second counts it seems
If I am not mistaken, you can manually set individual “relative flow adjustments” on the AMS for the P1P after you manually calibrate them. This would then allow for the best multi color/ material prints! I can’t believe that feature didn’t even make it into the X1 firmware release! I thought the X1 was suppose to be the more premium flagship product here?
