* New functions, Hysteresis and Zwobble. *
* *
* Hysteresis: *
* These are the extra distances that are performed when an axis changes direction *
* to compensate for any mechanical hysteresis your printer has. *
* Set the parameters width M99 X<in mm> Y<in mm> Z<in mm> E<in mm> *
* *
* ZWobble: *
* How to use it: *
* Set the parameters with M97 A<Amplitude_in_mm> W<period_in_mm> P<phase_in_degrees> *
* KNOWN LIMITATION (by design): if you redefine the Z value during your print *
* (with a G92 for example), the correction *will* screw up *
* How does it work? *
* This class compensates for a wobble of the Z axis that makes the translation *
* rod movement->bed (extruder) movement nonlinear. *
* Instead of assuming Zactual = Zrod, the function assumes that *
* Zaxtual = Zrod + A*sin(w*Zrod + phase). Since the user wants to specify Zactual, *
* we need to invert the formula to obtain Zrod, which is the value that will serve *
* as the input of the motor. *
