Speed display

[duebelpapst]

Hello Maxim,

I have noticed that sometimes 0 rpm is displayed for the speed, but when I switch to angle, the angle is displayed correctly and the thread cutting also works.
So it can't be the encoder, do you have an explanation?

Hi Stefan, RPM calculation averages over multiple readings and requires a short period of time to get established when you turn on the RPM display.

We only calculate RPM when it's needed -

nanoels/h4/h4.ino

Line 3018 in 4e57cae

if (showTacho || mode == MODE_GCODE) {

- to save processing time since it runs on the main thread which also runs the steppers.

If you want, you can change that condition to always calculate it - this way there will be no delay when turned on.

Thank's, that's what I guess, but I just wanted to ask to be sure.

Stefan
