Re: [CAD_CAM_EDM_DRO] Gecko Heat Sink

Hi Jon,

I'll see how EMC runs with them, once I get it up on a machine. Your
rate generator sounds interesting, as well. I just heard that the
G210's can run on full steps, possibly there's a jumper to change, or an
upgrade for them. They DO run smooth!

If steppermod can generate more steps/sec, then I should be able to
achieve higher rates, too. I was using my own code, and the rate table
only goes up to 150 IPM, and does not account for uStepping. That
should make it 10 * 200 steps/rev, right? Just like 1/2 or 1/4 step,
only more. What else is involved in driving a microstep drive?
