Ok so I’ve got my i3 built and x,y,z work fine. When I open Repetier and heat the extruder to 240 (ABS) I hit extrude and it extrudes fine. If I hit extrude a 2nd time the motor just jerks and acts like it doesn’t want to spin. If I however reverse it once it will extrude again. Unsure what the problem is.
I received my i3 mk2 kit in december 2016 and i have issues with the extruder.
It does not want to reach it’s max temperature for pla ( 210°C ). It go from ( 132°C up to 167°C then back down to 120°C then up to 137°C and so on … ), it does a roller coaster ride. It does that for 45 minute then cancel. I can’t get the extruder hot enough to load the filament. What can i do. It’s been almost 3 month and i can’t do anything with my printer.
