Hi Guido,

Error 81 is not specific to the brake, other things can cause it.

Does the drive ever spin-up?

If not: after the brake is released, try to flip the flywheel with the
eraser end of a pencil... sometimes this is enough to make it run. I think
you spin the front edge from right to left (counter-clockwise when viewed
from the bottom).

If the spindle won't spin-up without the flip, try adjusting the brake; but
I expect the motor (or the motor driver board) has a problem. I don't know
of a fix for this or what the problem is; let us know if you find out!

Good luck!

James
