When calibrating exp. pedal, heel will not go to 0. Toe goes to 255

[conens]

Hello;

Went thru calibration procedure several times on my newly purchased HD500x.  Toe is correct every time, but heel will not set to 0.  It sets to 26 every time I have tried to calibrate it.

Has anyone had this problem? Have you been able to get it corrected?

Thank you

Yes, exactly, point by point several times. Heel goes no further than 26, toe goes all the way to 255.

I think Nico is pointing you in the right direction. There is a thread somewhere where the user actually disassembled and cleaned the sensor but I would not take that task on lightly.

That would void my warranty.  I am still trying procedures from the link posted above. The controller suggestion doesn't do anything at all, but turns itself off after moving the vol. pedal.

OK, like chiolas in the link above, given by Guru, my pedal finally calibrated from 0 at the heel to 255 at the toe....the only thing I did differently than before is tap the C switch once more before slowly bringing the pedal back to the heel position. Crazy, but it registered 0 as I went the full throw several times to make sure it was done.  I saved it with the D switch, a P appeared, I powered the unit off and on, and all seems to be in order.

Thank you all for your comments.
