Prevent plastic to stick in hotend between prints Hi, I've been making tests with experimental and economic hotend for a while and it is going great. I still have a few issues when a print has been done. When the hotend cools and I start an other print, it is quite often jammed. The hotend is an all metal hotend and the inside surface finish has been carefully polished. I had problem with previous hotends having a bad surface finish, I couldn't even retract more than 0.25mm. Now it is doing fine with retraction. Thank you! https://reprap.org/forum/read.php?4,271310,271310#msg-271310 Mon, 16 Mar 2026 20:23:28 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,271310,271310#msg-271310 Prevent plastic to stick in hotend between prints https://reprap.org/forum/read.php?4,271310,271310#msg-271310
