I just purchased a taz5 and am experimenting with materials and ways to reduce print times as part of a project on 3d printing prosthetic legs. Two questions : first, has anyone tried larger alternatives to the stock .35 nozzle on the hexagon hot end? If so, is there a source? Second, has anyone installed the e3d volcano on the taz5? I’d really like to see if I can speed up our printing process using larger layers.
