Hi All, I am new to 3D printing so please excuse me if I sound idiotic at times. I have recently built a RepRapPro Mendel and am performing test prints with a single material (PLA). When performing test prints of a cube or even a flat disc of material I am having issues when randomly during the print the extruder doesn't seem to extrude anymore material thus leaving gaps in the piece (picture attached). I have performed the extruder calibration and it seems to be working fine but the problem still seems to arise. I have also cleaned the hobbed gear and slowed down the extrusion speeds but these inconsistencies are still present. Please help! I have found myself pleading with an inanimate object which is driving me crazy! Thanks so much! https://reprap.org/forum/read.php?154,250850,250850#msg-250850 Tue, 21 Jul 2026 12:59:45 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?154,250850,251144#msg-251144 https://reprap.org/forum/read.php?154,250850,251144#msg-251144 François Delègue Skeinforge Thu, 03 Oct 2013 05:27:22 -0400 https://reprap.org/forum/read.php?154,250850,250850#msg-250850 https://reprap.org/forum/read.php?154,250850,250850#msg-250850
