It's a good thing but, I am surprised by quantity of professional, and
experienced reply on a Homebrew named list...
If would buy a already made machine if wish a really good one. It's just
an hobby thing.
And as i said my wish is a 30-40.000rpm spindle. I can test if it handle
above that but it stops there. This is a cheaper dremel like tool, but
it can go faster or make less noise for the same rpm and have
replaceable bearings (they came in a box of 10), and maybe a better tool
chuck.
My questions related to use of DC with pwm on and AC brushed motor, or
where to post it on cnczone, didn't deserve answer like a balance
machine did.
