Calibration Box, Top Layers protruding

Postby Timon » Thu Jun 07, 2018 1:25 am

Hello everyone,

I am printing white PLA (Raise3D premium) material at 215°C. I am using the printer settings suggested by the ideaMaker for PLA high quality (changes: no raft, but skirt, 215°C instead of 205°C, because it does not stick to printer bed unless, no right extruder).
I am experiencing that the top few layers of my parts, including the calibration box, are protruding into the open space (see pictures attached). I do not know why this is. Can anybody help?

Thank you,
Timon

Hi
The reason is to high temperature and the short time for cooling the Printing element
Use the raft and made temperature to 200-205 degrees and 50 degrees on bad

Thank you Stanislav, this already improved the print quality by far.

Increasing jerk will give you sharper corners but will increase ghosting

Hello Mustachio,

it looks like I have already got an issue with ghosting. I went ahead and printed the part from this video here: https://www.youtube.com/watch?v=KaFp6Eqk0QI. It was not as bad as in the video, and it improved, after I put the printer down from a rather unstable table onto the stable ground. However, the signs of ghosting are still clearly present, when moving the part from side to side, while it is shone on by a light source.

Thank you very much for the advice though. I might try playing around with the jerk, when I have a better understanding of the more basic things of 3D printing.

Cheers,
Timon
