I'm not sure you need any of these. Most Linux installs

KERS = Kinetic Energy Recovery System. Various means of capturing some energy
during braking then using it to help accelerate out of turns. IIRC Formula 1
never fully implemented used of any KERS device due to some chassis

I'd love to Andrew, but its long, and the simplest version would be from
the pi4b running the sheldon. But I just found that for the first time
i have a friend that pulled apart a old 100+ kw vfd and collects caps.
he has buckets of massive ones

From what I could understand gene is using something similar to the old
KERS used in Formula 1. I don't know if this is a common practice because
it's really good idea. May be the only drawback is the cost of the
capacitors and that's why we don't see this approach very often.

OK gene.
I'm all ears . Love To hear how this works. Maybe put the relevant code
here.

If you wanted to do it based on commanded spindle speed, then
"lincurve" would probably work.
Alternatively, you could consider basing it on spindle.0.revs, noting
that a threading pass is unlikely to get
Hey everyone just a quick reply here.
Jon yep I have a braking resistor.
So I have the spindle accel and decel running through a limit component.
Constraining rate of change.
Which works quiet nice.
And I am have a custom m code that increases rate of ramp when rigid
tapping. So I can do

Hello Andrew,
Is there a baking resistor installed on your drive? I think a proper one
should solve your problem and you can keep the good deceleration rates.

Possibly, if you were to add a limit2 component to the hal. That would
limit the _rate_ of speed change, not the time.
It might be better done at
