No, that's not making sense. But extrusion (A-axis) on combined xyz-speed would make sense. You could do extrusion completely different If you make A-speed dependent (I did linear interpolation with a QD75 module once) of xyz-speed. Setting "width" of the extrudate would translate as "speed". As an added bonus a little temporary offset of the A-speed as a function of the xyz speed/acceleration would account for hysteresis in extrusion due to nozzle pressure (I think). At least that could be tried/tested then. :) > > > -- > atp > If you can't fix it, you don't own it. > http://www.ifixit.com/Manifesto > > ------------------------------------------------------------------------------ > Learn Graph Databases - Download FREE O'Reilly Book > "Graph Databases" is the definitive new guide to graph databases and their > applications.
