@chrisyt got it! Thanks!

The best option by far is to design/model the support yourself if you can, particularly for these kinds of models – if you need help with this, let us know.

Do you mean there are some ways to generate support using 3d party software, or I should just draw it during part designing?

@chrisyt yes, I have drawn the part using Autodesk Inventor and printing it in the draft mode.

Your response is very helpful and sounds logical for me. I will try to play with the ‘Support Z Distance’ parameter and also design future parts considering the fact you told about.

Many thanks!

Dear @chrisyt,

please find the file attached.

Dear @pete,

I will check it and report later. Thank you for the detailed explanation!

BTW, it looks like the shift was accumulating.

@chaad @click right, at Thingiverse.

0.3 (mm?)

I made the nozzle height calibration again and made sure again, that the paper can slide not touching the nozzle. I have also cleaned the surface and will try again.

@bhudson then I don’t understand, why these wrinkles appear always at identical positions of the printing bed. I though it has something to do with the first layer adhesion.

There was a comment about coating the nozzles with silicon oil, which helps against molten filament sticking.

@pete That worked for me! Thanks!

Open the assembly file
Isolate object 1 (others were hidden)
Save as … (for instance 1)
ctrl+z (all objects visible)
Isolate object 2 (others were hidden)
Save as… (for instance 2)

n. import all files simultaneously into AM. Profit.

@bhudson I could import single parts simultaneously but they are both lying on the ground, though one needs to be on another. If I create an assembly in the inventor I can add constrains, so that the parts are correctly connected. If the parts are independent, then they are imported without considering their correct respective positions.…[Read more]

@click absolutely right! I recalibrate the height and everything is perfect! Actually my first layer was too squashed. During calibration the sheet of paper was still touching the nozzle. I recalibrate and did as asked - the sheet has to move without touching the nozzle.

I do not use brim, as the parts are thin (1.6 mm).

@pete I have polished the bed with a sandpaper. But what was important is a proper hight calibration. My printing head was just too close to the printing bed.
