I recently bought 2 bear upgrades and decided to increase the z height to about 569 mm.
I am using the firmware 3.9.2 release and compiled it via Ubuntu.
I changed Z_MAX_POS to 569but i guess that is not enough:
The printer always goes to the top end leveling the Z axis.
Then it asks for nozzle cleaning.
After confirmation the Z axis goes down
It tops about 10mm above the bed aborting the calibration "Z calibration failed, check axis".
-> Changing Z_MAX_POS to 555 or 565 did not change that behaviour.
I looked around the web to find an explanation what is needed to change in the FW in order to run a successful Z-calibration with modified Z but was not successful.
May you explain what is needed to be changed besides Z_MAX_POS?
The only other modification I made was uncomment #define FILAMENTCHANGE_ZADD 2 because otherwise I got compilation errors (Z exceeding 256).
