Hi
I build a custom z axis and used quite too much material and it's quite heavy. I'm just missing the stepper, but i really wonder about it.

Driver run at 48v and 4.5amp set of max 5a.

The whole z axis metal parts, carriage, sfu rod... and the 2.2kw spindle weight about 70lbs

I run a SFU1604 ballscrew and fit a 3:1 belt ratio. From stepper to the sfu.

So is a 280oz low inductance stepper will be ok ?

* mostly cutting wood and alu from time to time

thanks
