I certainly understand that a heavy mill may not be able to move as fast as a very lightweight 3d printhead and printing may take a long time. However, why would "filament control dynamics" be a problem? With the mill the table would be moving and the filament stationary which should, if anything, make the problem simpler. What am I not understanding? Or are you concerned about the movement of the object being printed? I have not experience with 3d printing. How fast do the typical inexpensive 3d printers move? ------------------------------------------------------------------------------ Check out the vibrant tech community on one of the world's most engaging tech sites, Slashdot.org! http://sdm.link/slashdot _______________________________________________ Emc-users mailing list Emc-users@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/emc-users
