hi all, i just assembled a new reprap. parts coming from my previous build except for a new hotend. whenever i print, first few layers comes out a-ok. after a that, filament isnt as continous as it was. there are breaks in the prints. google for the trouble and came across this [www.reddit.com] my question is: what is the solution to a gummed hot end? thanks in advance. https://reprap.org/forum/read.php?262,329150,329150#msg-329150 Sun, 07 Jun 2026 01:43:50 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?262,329150,330544#msg-330544 https://reprap.org/forum/read.php?262,329150,330544#msg-330544

What hotend do you use? Do you have cooling at the upper part of the hotend?]]> Ralf Printing Mon, 24 Mar 2014 05:26:49 -0400 https://reprap.org/forum/read.php?262,329150,329151#msg-329151 https://reprap.org/forum/read.php?262,329150,329151#msg-329151 f3rDz Printing Sun, 23 Mar 2014 22:34:21 -0400 https://reprap.org/forum/read.php?262,329150,329150#msg-329150 https://reprap.org/forum/read.php?262,329150,329150#msg-329150
i just assembled a new reprap. parts coming from my previous build except for a new hotend.

whenever i print, first few layers comes out a-ok. after a that, filament isnt as continous as it was. there are breaks in the prints.

google for the trouble and came across this [www.reddit.com]

my question is: what is the solution to a gummed hot end?

thanks in advance.]]> f3rDz Printing Sun, 23 Mar 2014 22:32:23 -0400
