I ve got my Mendel Prusa i2 up and running after a few glitches. I dowloaded a simple test piece from thingiiverse and,fingers crossed, pressed print . The printer started up ok for the first 6 or 7 layers but then started to drift. The extruder moved out beyond the original footprint and naturally ended up making a messy blob. Can anyone suggest what is going wrong? https://reprap.org/forum/read.php?4,493416,493416#msg-493416 Sat, 11 Apr 2026 07:55:05 -0400 Phorum 5.2.23 https://reprap.org/forum/read.php?4,493416,493638#msg-493638 https://reprap.org/forum/read.php?4,493416,493638#msg-493638 imakebiodiesel Reprappers Mon, 06 Apr 2015 18:27:57 -0400 https://reprap.org/forum/read.php?4,493416,493424#msg-493424 https://reprap.org/forum/read.php?4,493416,493424#msg-493424 ggherbaz Reprappers Mon, 06 Apr 2015 09:33:04 -0400 https://reprap.org/forum/read.php?4,493416,493416#msg-493416 https://reprap.org/forum/read.php?4,493416,493416#msg-493416 imakebiodiesel Reprappers Mon, 06 Apr 2015 09:17:44 -0400
