Creaking of the nozzle about the product

Hi, I have about 5 days in the printer. From the beginning problems with the perpendicularity of the frame, on different tables it showed that there are oblique axes. I tried the printer without dividing it into a small table and everything is perpendicular 🤣 I probably didn't notice it during the first prints, but the last few prints come to me that in some parts the nozzle throws a model 😥I have the first layer reduced by -1,535. Please watch the video. I will be grateful for any advice 😀

Here is video* https://forum.prusa3d.com/wp-content/uploads/2021/01/20210126_1345151.mp4

RE: Creaking of the nozzle about the product

Your video shows no strangeness. What is interesting is to see what the bottom of the detail looks like, that is, the appearance of the first layer.
So make a square with the dimensions 75x75 mm that is 0.2 mm thick. It wants to clearly show if your printer is properly built and properly calibrated.

I'm sending a photo of the square here. One corner is fine, but the rest didn't come together. Where do I start looking for a problem? Thanks for advice.

Setting in your printer, set calibration to 7x7.

Check your bed with a metal ruler, to check if it is flat, I saw on youtube several movies on how to get it flat, if it is needed.

Most important for 3d printing is:

1. Clean bed, wash bed a few times with dish soap and a lot of hot water.

2. First layer needs to be 100%.

Both settings are needed to get a good print, to get print good sticking to bed, and avoid a model sticking to the nozzle, or releasing from bed.

In your movie I think you need to go lower with your z layer. search on youtube you see examples how to do this.

Alcohol does not clean everything, yes you can do a few cleans with alcohol but then you need to do dish soap again, and use a lot of alcohol if you use this.

Your picture shows that you need to lower the Z level a little more. A perfect first layer gives a completely dense and smooth surface without gaps.
I also assume that you have not changed any other Advanced or Expert parameters. In that case, you should restore them.

So I tried to reduce it. It seems to me that there is a difference in the filament. Silver from Průše can withstand the Z axis higher. The cheap filament must be a little lower. I'll send photos tomorrow.
