peratures – try increasing the retraction afewmillimeters
(3 or 4 millimeters). For adjusting the retraction if pr i nt-
ing through the Polar Cloud, under ““PRINT SETTINGS”,
“ADVANCED”, “Retraction”, adjust the “Amount”(andper-
haps the “Speed”oftheretraction).
5. If cor n er s a re messy or blurry or (unintentionally) rounded

(corners), the print speed may need to be slowed down. To
slow down the entire print, if printing through the Polar
Cloud, under “PRINT SETTINGS”, “BASIC”, adjust “Print
Speed”.
6. If surfaces have blemishes where the interior print mate-
rial shows through or penetrates (telegraphing), the exte-
rior shell of material may b e too thin: modify the print
to have a thicker exterior (u s e more shells). In partic-
ular, if printing through the Polar Cloud, under “PRINT
SETTINGS”,“ADVANCED”, “Quality”, adjust as relevant the
“Wall Thickness”, “Bottom Layer Thickness”, and/or
“Top Layer Count”.
7. If tall and narrow sections of the print look squish ed or
melted, the print may be happening so fast, with one layer
