RE: [CAD_CAM_EDM_DRO] Re: USB 2.0 CNC control and high speed stepper driver

Hi Hugo -

Cool! We'd all love to hear more about this, but the language
barrier might be a problem. There seem to be some skeptics of
running steppers at 2400rpm and 80% rated torque, so if you can,
could you get more details on that?

Regards,

stepper driver

Hi

I know one company who use their systems, I've visted them about a
year ago, the control they used cost about 5000 dollar, I'm not
sure
what their prices are now. The motors they use get indeed very
hot,
so they use a lot of cooling (cooling body and a fan), I also know
they done a lot of searching of finding the right motor (low
resistence). The video is very impressive and I will contact them
next week, easy for me because it is a dutch company and I'm also
dutch. I will let know the results.
Thanks you Carlos for post.

Hugo
