Re: [CAD_CAM_EDM_DRO] Two stepper on one spindle

Hi Boris,

Well, I suppose one could do that. You'd need a second driver for the
additional stepper (don't try to drive two steppers from a single
driver), and another motor mount. You'd also have more inertia at no
extra charge (not a good thing)! I think I'd spend the money on a
bigger stepper. Are you running a chopping driver? If not, then
converting to one (usually requires a bipolar setup), or raising your
voltage if you do have one will help get all you can out of your motors.

I switched my old Sears/Sherline mill from MaxNC 4-phase drivers to four
G210's and 180 oz/in steppers, and even at 37V, boy can she move! No, I
don't need the 90+ IPM she'll do, but it's nice to have! Makes me start
thinking of adding limit switches, 'tho.

Now for a router, using a pair of steppers makes considerable sense.
The dual 'X' axis each get a stepper, and if desired, a "jack shaft"
between them keeps them in sync.
