I've designed a piezo mount to get some autolevel setup, was going to use polycarbonate filament. There is a globule of filament which builds up around the nozzle often breaking free wreaking havoc. Have never had this issue with abs, what is the cause of this. any steps to resolve the issue. Layer height seems okay and extrusion is calibrated retract is 7.5mm not sure what to do about it. https://reprap.org/forum/read.php?4,803539,803539#msg-803539 Wed, 15 Jul 2026 05:42:15 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,803539,806022#msg-806022 https://reprap.org/forum/read.php?4,803539,806022#msg-806022 Roger123D Reprappers Wed, 17 Jan 2018 21:06:32 -0500 https://reprap.org/forum/read.php?4,803539,803539#msg-803539 https://reprap.org/forum/read.php?4,803539,803539#msg-803539 what is the cause of this. any steps to resolve the issue.
