Re: Home cnc project

Thanks Dean,
I got started with the motors first and then built the mill. I have
my concerns about the power and I have been looking around at options
for upgrading the stepper motors, if they are not powerful enough.
Right now I want to see it move. I hooked one motor to a ballscrew,
and was surprised at the amount of force the nut could exert. I
don't know how fast it can go yet.

Glad you told me about the Rotozip. I will look at the dewalt

Bill.
