Nozzle offset calibration error after upgraded from 2T to 5T

I've just finished upgrading the XL 2 Tool to the XL 5 Tool.  Did the reset and restarting all initial calibrations.  But stuck at toolhead offset calibration.  During that calibration phase, the printer seemed to lift the nozzle instead of dropping the nozzle around the calibration pin.  Leading to an Pin Not Reached error 17107.

I do have the  Alpha firmware 6.00 flashed.  Anyone else gets this?  Can I downgrade to the stable 5.1.2 firmware?

RE: Nozzle offset calibration error after upgraded from 2T to 5T

Did you resolve this? I was having the same problem after 2T->5T upgrade (after 1T->2T), but it's resolved now.

Mine was due to a few things below. 

1: The toolhead 1's nozzle was too dirty. Obviously, this nozzle was most used. I've replaced the nozzle with a new one.

2: Forgot to place a steel sheet during the first stage. At first, I didn't know why a steel sheet is needed first and then needs to be removed shortly after. Yes we need it. It is calibrating Z height I guess:) Following the process exactly helped:)

Firmware 5.1.2. (downgraded from 6.0.0-alpha due to dock calibration issues.)

RE:

To flash an older firmware the procedure is as follows:

Push the reset button, immediately followed by double-pressing the selector knob. On the new screen, confirm the update by selecting the "FLASH" button and pressing the knob.

It says Mini but the steps are the same for the XL.
