A Well meaning But absolute incompetent frankly got his hands on it . Told me he could help and apart from the terrible soldering he totally guessed what to do and replaced sensors without even checking them . I’m told he replaced them with wrong type 49e . Then he replaced a faulty what I think was a resistor at R2. But he put a capacitor there . I think the board will be replaced . Seen on Ali express . I want to eliminate wiring faults if any first
Looking at things briefly, it doesn't look like R2 does anything if no speed limiting wire is connected, (it doesn't look like there is a through board connection at the pad). If that's the case it shouldn't make a difference if it has been swapped with a capacitor.
I'll have another look at mine tomorrow.
Do you have a link to the Ali express board?
