Extruder spins on print start after warm up
For some reason my Prusa i3 Reprap printer with the latest Repeiter firmware will most of the time - start spinning the extruder for minutes before it moves the print head to the appropriate position after the bed and extruder hotend have reached the set tempurature. If I kill the print job (resetting the Ardunio) and restart the print then it seems fine. Not sure what to make of it. Can anyone help out?
