So why go vertical when horizontal was such a win before?
Log from Minamil 2dc: a minimal CNC mill
When HaD editors gave #CDCNC , the one-off precursor to this project, its 15 minutes of fame, they commended the Z-horizontal layout which avoided lifting the heavy tool with a tiny motor & gave chip clearance for free. So why abandon those advantages?...
