TNGv2 Spindle Speed Recognition is unstable

[Gnewko]

Hi, the spindle speed "recognition" in the new version of TNG software is very unstable (I use an encoder with index). The software displays it periodically and permanently (in very short time interval) between 1802 and 2073 revolutions per minute (of course the spindle itself turns with constant speed without any load). In the old version it was much better: 2000 - 2001.

Spindle RPM measuring did not change.
Please export your profile (menu File/Export Profile) and send zip file to PlanetCNC email. I will check then what is wrong.

Thank you, already send.

I generated 5 MHz quadrature signal simulating 100 PPR encoder and I got stable 3000 RPM.
