Revision to Reducing Stand-Still Noise

Manuel Coenen

=== Preparations ===
+This requires RepRapFirmware 2.0 or later.
+
Only tune '''one motor at a time''' with no idle-current-reduction. Do it as follows
|--
| 4
-| ``M569 C65971``
+| ``M569 C65972``
| Default
|--
}
-All of these commands need to be extended to address the motor being tuned by adding the apporiate ``Pnnn`` parameter where ``nnn`` corresponds to the driver number starting at 0. So usually X=0, Y=1, Z=2, E0=3, E1=4, etc. Nothing else needs to be added. The effect (if any) will be immediately after issuing the command.

Generally ``TOFF`` values above 10 will give a very unpleasant high-pitched noise but you can of course still try all values to be sure.
