Get the 11" stove elements. A 2400 W element

The VFD manual will suggest a resistance and power. But I would
imagine there is a fairly wide acceptable range. (especially

I _think_ that I run 19200. But I would need to walk out to the
workshop and boot the mill to find out, and it's 0120 here.
I can get you the full loadusr string tomorrow.

Yes, as I wrote above, the resister specs depend a lot on how often you
intend to reverse the direction of the spindle.And how quickly.
A resister of "infinite" resistance (open circuit. eg "no resister at all")
can work but will give lower performance braking power. This would be

Using too low a resistance won't harm the MOTOR, it will blow the

Right. The newer drives chop current off the DC bus to the braking
resistor to lower the DC bus voltage as the motor slows.
I'd find out what they recommend.

I am running master on all machines, including buster on the small lathe,
its not there in the man9 pages.

It's been in the regular release since 2.7

I doubt you'd really need a braking resistor for running a router spindle (what
I believe you have.) Simply test it without one, as long as you don't get
overvoltage alarms on the VFD when decelerating you should good without it
(assuming your VFD has adequate safety alarms which might be a big
