Hi Dommy,

You have a really nice workbench !! I wish I could have one like that :-)
So the problem doesn't come from the power supply.
And as you can set the input voltage you want, you might be able to compensate the smaller number of turns in the coil (if that's the problem).

But looking at the pictures you sent, the display screen shot doesn't look quite normal.
What it says is that the magnet is levitating 'higher' than were you ask it to be (the blue line) and that the control loop is not able to make it go down. Which seems kind of weird: the control loop is not able to let the earth gravity do its job !! ;-)

Indeed, the lower the value of the red line, the closer it is suppose to be to the sensor.
So, my guess is that you got the orientation setting the wrong way.
Can you double check your configuration as explained in section 8.3 of the manual ?

What you should have:

  • when putting the magnet under the sensor and moving it up to the sensor, the red line should go down.
  • When the red line goes under the 'actv threshold' value, the coil should turn on
  • When turned on, the coil should attract the magnet.

If that is not the case,

  • check the 'sensor reversed' checkbox the press the send button.
    Then flip your magnet the other way and re-test everything.

Also, your sensor filter and coil filter seems to high.
'Sensor filter' should be around 2 or 3
'Coil Filter' should be 1. (I should remove that option, as it doesn't really help)
