PreenFM2 encoders

(1/1)

zelea2:
Since I don't have a PreenFM2, I don't know what to expect as behaviour for the rotary encoders. Can someone please let me know how responsive they are?

The best I've obtained on my PreenFM2 version is about 4 steps per second with reliable detection and no back-skips. I've improved my detection as much as I could and the software is supposed to catch up to 25 steps per second but I don't think these encoders can handle that kind of speed (at least the ones that I have).

Is 4 steps per second acceptable or are your encoders better?

zelea2:
No one? This wasn't a difficult question though. Just let me know how fast can you turn your encoders while still registering steps.

It's at least 6 or so by my really crude testing.

Thanks for your testing. I've got that too now, between 6-8 steps per second without skipping. Turned out I just had to be more aggressive with my timing. 8ms high followed by 8ms low is considered a step and works fine.

Cool. Hope it helped.
