That sounds appetizing, but the glacial speed doesn't. > On Tue, May 16, 2017 at 6:27 AM, Gene Heskett <ghesk...@shentel.net> wrote: > > Greetings all; > > > > And the next logical question from me is: > > > > Has anyone put a printhead on a std moving table milling machine, > > and used it to do some 3d additive printing?
