Why does this happen?

Height 0.3mm (initial layer, all other 0.2)

The video you link to is worthless.
It does not say much.
How to measure the distance between nozzle and 3D touch top for an example?

You have no examples of how to do this, its just guessing here.

Material is PLA, Room temerature 20°C. That is the conditions.
Any recommendations for this environment?

Now with the 3D touch sensor it makes the job even better ...

But what is the longest recommended print time for this printer?

The longest print so far I have completed was 18 hours. But I have a print that will go for 32 hours soon.

So what is the maximum time the printer can print?

You should not tighten the feather screws, only adjust it so the nozzle head is tight to the bed.

Hi friends

I am new to using 3D printers and have my A20 machine which seems to work okay, sometimes.
What kind of 3D software do you recommend using when designing objects to print?
