Hi,
I have a strange problem: When I start a print, the printer goes through the steps of the start script (basically Homing, Autolevel, go to side and wait until everything is heated), but while it waits there, suddeenly the extruder motor starts to run frantically backwards. I have this issue with Slic3r and Cura gcodes, but not when I type the entries by hand in Repetier host. The running starts at about 150??C which fits to the #define EXT0_WAIT_RETRACT_TEMP 150. But it doesn't retract just a little bit but endless.
Can you please help before I start throwing things at the printer? Thanks in advance.
