Hi,
?
I¡¯m finishing up one copied digital project (Arduino-controlled lathe motor speed controller) and am nearly ready to wire up on another (wood lathe RELS), and have an extra, cheap Nano copy in hand.
?
I¡¯d like to start collecting the parts needed to add a stepper drive to my small geared dividing head and wondered what motors that would be adequate for the purpose.
?
My dividing head is a home made 40:1 unit with about 3¡± swing. The way I use it it would be easiest to mount a stepper on a kind of banjo, with a belt drive which gives options for more torque at the cost of speed. Motor weight will be an issue in any case.
?
Would a 100oz-in NEMA 17 be enough? It does have a spindle brake.
