Hej!

I saw your post from 2 years ago regarding recalibration of speed sensor for volta/electrolux vacuum clean.

I have now spent 2 days trying to recalibrate the same board but I am having partial success.

I am able to set values corresponding to minimum motor power and turn off, but to get motor to full power I always must turn it all the way clockwise toward the mechanical end of the potentimeter.

I read your explanation for calibration many times but perhaps I am misunderstanding something.

Can you please try to explain this again? If you are in Stockholm I can buy you lunch, otherwise I'll gladly swish a donation. This is driving me crazy.

Thank you!
