I recently bought a PreenFM3 used. The seller had built tis unit himself.
I have noticed a intermittent misfire issue with button #1 of the bottom left 6x button matrix.
Every few presses it does not trigger.
Observations:
- I have turned the unit on approx 6 times over various days - sometimes the issue is there, sometimes not. 50/50
- If I tap very far to the left of the button, there is none
- Tapping to the centre or right of the button results in misfires.
- I tried a whole combination of different ways to press it. Momentary or long presses, same result.
Has anyone experienced this behavior and if so, do you think this is a software or hardware issue?
Maybe someone can suggest some things to try.
Thanks so much for reading
