Someone will have to verify this and it's only meant to help the exploring, but I think if you issue a 'G92 E0' it will zero the extrusion length. You might be able to put this as one of the last lines in your 'Start G-code' in the Slic3r 'Printer Settings' and disable that "large amount of material" from being extruded.
