The winder is not started/stopped if USE_WINDER_STEPPER is defined Bug fixed where winder was not stopped on "Stop extruder" Renamed the winder pin to make it clear it can be used a fan
- Only reset the winder fan speed in main loop if the extrude_status if the extrude_status is enabled. Otherwise it keeps resetting the speed even if set to a value by Gcode or LCD.
- This is to fix a bug where first move after resume was planed with old value of current_position.

This pullrequest implements an option to use
Xaxis stepper motor as a winder instead ofPin 8DC 12V motor by uncomenting#define USE_STEPPER_WINDERin the configuration.h file.Pin 8then works as ordinary cooling fan.This implements feature described in #15.
When working on the feature I found 2 bugs that i fixed:
When motion menu was used to move an axis, the planner used old current position of
XorYorZaxes to plan unwanted move when extrusion was resumed. The issue was fixed by clearing the stepper positions besore resuming the extrusion.When DC motor winder on
Pin 8was used the winder did not stop when extrusion was paused. Thus the winder became unstoppable. I fixed the issue by settingwinderSpeedto0and in the main loop the speed is set towinderSpeedonly ifextrude_stateis enabled.
