lukasz_b_g When I press stop on a print, the extruder starts to turn at a high speed, grinding filament and extruding massive blob.The speed at which it turns is approximately the speed at which it loads filament, as I have a bowden extruder.
Repetier Check your stop print script in host. Normally it is empty but if it moves extruder I guess you have some extruder gcode there. Often users forget that in print E can be a big number and coordinates given make no sense unless they addG92 E0befor ethe E move to have a defined position.
lukasz_b_g This is what I have as my end script, it was working fine, until it stopped working at all.G91G1 X0 Y200 E-1 E7500G1 Z40 E-1 F300G90G92 E-6
lukasz_b_g As I posted it I realized the mistake, it should be F, not E. Thanks for making me realize :)
