Here it is in 618. Slight warpage on the bottom flat plate, and a little overheated on the top of the ball (why don't slicers sense that the head is staying in the same area and reduce the temp a bit?). Did another in 645, will see how it came out and post photos tomorrow.
Do you have an idea what could be the shorter delivery time to Slovakia provided by US post office? I red it is about 5 - 7 days for envelopes under 50g.
It’s on the printer we are not allowed to use nylon. Surface looks great and support removing was easy as with ultrat. Just need to clean inside areas from nylon fibres. There was no warping with the orientation I showed at the top, since only small area are touching the platform.
