Bondtech Upgrade - Multiple failed Z-Calibrations
I've just upgraded to a Bondtech E3D V6 kit. Since flash updating and system reset (ALL DATA), I'm receiving an error stating "Calibration failed. Check the axes and run again." The z-axis touches heat-bed and does not retract. When I system retract, it shows z at a height of 5+, while it is mildly depressing the heat-bed.
I have adjusted the PINDA multiple times. It also seems that the LED on the PINDA isn't consistently on or off during calibration. I should add that self-test of components passes. Auto-Home under calibration sends the probe dead-on to the lower-left spot on the heat-bed.
Any ideas of what's going on? Have I a faulty PINDA? And if so, is there an upgrade to the current one?

Did you flash using the firmware provided by Bondtech? The Bondtech extruder reduces the Z distance by about 5mm.

Thanks GREATLY for your help. This was exactly the problem. I had flashed and re-flashed the firmware, but it took a third time to set right. I'm not sure what the foul-up was with flashing the firmware, but seeing your response prompted me to attempt once more.
Thanks for your help!
