Well.
I finally have a machine that can do work.
Stats: (hehe)
22x14x6" travel (yes... 6 z, though the cutter eats up quite a bit depending on operation. still running basic keling 4030 kit. want to upgrade to 36v power supply... 1.75hp porter cable spindle. my idle mind is trying to imagine an affordable tool changer idea.. its a tough one.
thk ground ballscrew on long axis, ebay'd linear rails on all axis. 15ipm on z, 140ipm on long axis, 50ipm on short axis, soon to be 70ish when i put in this 5tpi nook ballscrew from mcMaster.. To my horror, the balls all fell out even though I thought i was being very careful - anyone know how to fix this?! can it be fixed?
And now, the pictures.
