the way i see it :

long 3d toolpaths with serious material removal rate requirement → more spindle power needed hence 2.2 and even better 3kw /for home use/ → heavier and stronger Z with long travel /remember deep bowls/ → stronger gantry → heavier build → at least 70kg gantry with all mounted




Dean, i agree, The trochoidal path was only to test vacuum fixture, machine and board capabilities. I wanted to see what happens when cutter is routing full depth. Now i use again HSM technique, instead i changed depths with width and dont use trochoidal path, except for profiling the piece and also its only 3mm deep as deeper leads to chipping of edge. If that makes sense.
