Auto zero Z axis problems

[JAZZCNC]

Ok I just checked both the simple Z Autozero routine and the main tool change routine and both are set to 250mm/min fast probe and 25mm/min slow probe so you shouldn't be getting this problem unless your routine is cocked up or the probe/plate is dodgy.??

Its 2010, the led for the contact plate lights up but motor takes about half a second to decelerate!

Seems strange happenings esp has you've mentioned changing motor settings etc so don't suspect it's overtuned.??
What size machine or more the point is it an heavy Z Axis with large spindle using small motors.? . . . Z axis specs will help or a pic.!! . . Also what are your velocity and Acceleration settings.?

Has it always done this from day one or just developed.?
