| Mar 15, 2016 at 14:23 | comment | added | kamuro | Eric is calculating the ratio of the two cross-section areas of the filaments, assuming (probably corretly) that the force needed to push the filament through the hotend is linearly proportional to this cross-section area. This also assumes that the finally pushing hobbed bolt or gear has the same diameter. The answer hence is highly incomplete and lacks all explanations. | |
