Lidar problem?

Hi everyone, I recently got the xc1 carbon, I’ve already printed a few projects on it, so far everything has gone smoothly so far. I noticed that the prints are starting to have small holes or indentations in certain areas, I tried to disable the lidar and in fact they are no longer there but I lose print quality. I’ve attached some photos so you can actually see what I mean. This problem came up without context as in previous prints it didn’t do it and now it does (same slicer settings) if anyone can give me a hand I would appreciate it. Thank you



I would start by cleaning the build plate with IPA.
Most of the time, the build plate is not clean enough.

Usually to clean the build plate I use non-IPA but still good quality isopropyl alcohol. I’ll try to clean the plate even better

Sorry? Where I live IPA = isopropyl alcohol - so what non IPA , but quality isopropyl alcohol.?
do you mean like household isopropyl alcohol, like 70\80 % not 100% chemical lab IPA

Yes, I mean it’s 99.9% isopropyl alcohol, it doesn’t say IPA but I think it’s practically the same thing

Yes, its ‘IPA’- IPA is literarlly just the shorted name.

It doesn’t need to be 99 or 100%, 91% works just fine for cleaning and is a good deal cheaper. 70% works but can be very slow to evaporate. IPA dissolves oils, but then you need multiple wipes to remove the solution before it evaporates - turn the towel to an unused area frequently to avoid re-contamination of the plate.

Though for cleaning the build plate, washing with warm tap water and a good grease (skin oil) cutting dish detergent (Dawn) followed by a thorough rinse is the most effective.

Thanks, I’ll try, usually every 3/4 prints I passed him a piece of paper soaked in alcohol until I didn’t see any thickness due to the glue (I use liquid bamboo glue)

I tried the solutions mentioned above (clean the plate properly) I also did a test with a new cold plate yet to be opened but nothing continues to have those under extrusion points. Subsequently I tried to use the Pei plate (also new) without doing the flow calibration (as indicated by bambulab) but as you can see from the photos it continues to have those dots/holes in the print. I don’t know what else to do does anyone have any solutions?? I’ve had this printer for a month and in the first prints it didn’t have these problems. Thank you
