Geeetech Acrylique Reprap Prusa I3 Pro B filament retraction

[bang]

Hi,
Did you fix it?
Did you feel the retraction with your hand and check the direction of your extruder motor(maybe move upward always?) when that happened?

hi yeah i finally fix it....
probable i did something wrong with the 1st set up cause i delete the repetier and load it again and works.. but only if i have it with my lap top connected if i do save to sd card and try to print it make every second auto home...... not sure why ....
thank you for your respond
