Not touching the bed

Since my R2 update its firmware to 2.0.0-r2.6 yesterday my printer nozzle won't get close to the bed to print. You can see on this short Youtube video what is doing:

Any suggestions?

 

One of the biggest changes with the firmware in this update was with the memory structure (EEPROM) of the motor control board. To make it compatible with the new OS and autoleveling features, we had to reset the EEPROM in order to rewrite it. This would have erased your stored Zoffset at the same time. The fix should be as easy as setting your Zoffset via the wizard on the LCD screen. If that does not fix it, please let me know and I'll follow up with another thing we can check.

 

Thanks that seems to have done the trick.
