I am using Buldtak and its the reason why i have an Offset of 0,42 in PLA files and 0,52 in ABS.
If you are using Kaptontape please remove the Offset and reduce the bed temparature for PLA down to 40°C
For ABS you can keep 100°C or going down to 80°C
There is also Faberdashery PLA an file. (I have an resetter
You should print always multiple parts with Faberdashery Filament, because the printer has no cooling fan and you will have somtimes (in less cases) some trouble with fine details. From stringing i Was suprised because Orange was working the best when i tested the "Rainbow colour" set, ecept white, which i haven't tested so far.
