Brother TC-225 / TC-229 adventure!

whats a number to start at for I?

I was a bit surprised how well is came into shape myself, ive tried to tune a few servos before (and easy servo-steppers) and its always been way harder for me. I suspect the drive itself internally is very well tuned making things a bit easier. I mean, I had the following error set at .010" and the default tuning settings let me get up over 100ipm.

soooo, whats the status on jerk control (s curve) anyway? is that coming along, or is it years away?

I reaaaaaaaaaaaaaaaaaaally want it

I would probably try 0.000001, then 0.00001 and so on.

ah, cool.

ok, one last thing I'm about to tackle after I get the y and z and spindle turning...

homing. wiring the actual switches, then making Linux use them as an actual home is easy, but that's not what these are meant to do. they are meant to be home "area" switches, and then the encoder index is used as the actual home position.

how do I go about setting that up?

That's super easy;
HOME_USE_INDEX=1

Limits working woot. There's actually a check box for that. Ha.

So next thing.... spindle.
It spins... but it's not accelerating or decelerating fast. I didn't see a setting.

More than that though... where do I start with orientation?

Thanks
