I got the printer working!

But then it follows a bunch of new questions.

1: I am struggeling with first layer adhersion. Do i set z=0 with a paper between the bed and the nozzle?

2: The print with PLA is sticking to the bed, but I am struggeling with PC. PC is sticking to the nozzle. Is this taped on bed sheet bad?

This is PC.

3: The probe seems to measure inconsistent depending on temperatur. Is it because I have a cheap probe, or should they only be used for low temp printing? PC is printing at 260C hot end and 90C bed temp.

4: How do i set up time left the right way? After some time the countdown seems to be on point.

5: This is my temporary rigged extruder and filament holder.

Any suggestion how I should change this setup for a direct extruder? I am going to heat up the chamber and have the filament inside the case.

6: How do you guys attach the cables for the hot end, to the case?

7: I am struggeling with the setup for bed mesh leveling.

The probe won't measure more to the left than this. If I change the probe X-offset from minus to plus, then I can. What is wrong?

8: Should i use set up m671 to get better compensation for the prints?

9: The parts are printing to small. Where is the best place to calibrate the print size? I printed a cylinder with Ø: 25mm and height 25mm and the part became Ø: 24.56mm and height: 25mm.

10: Does the g-code for the test print seem OK?

This is the first lines, the whole file was to big to upload.

Should I just buy a Bl touch so i can use a glass bed? Should i buy a E3D Hemera and new sensors? What filament sensor should I buy? Any tips for good webshops for parts?
