A user in the KS page indicated a 'first-time' startup bed leveling procedure whereby they moved the X and Y axis and leveled the Z at each corner point.
note this is NOT the Z calibration. But the bed itself.
I never had this happen - even after attempting a revertive flash to an older and then back to the current firmware.
This leaves me with two questions.
a) Given I am getting a number of leveling issues in my 3d prints (gaps in layers/wobble) I would dearly like to know how to force a leveling calibration.
b) How can I 'reset' the onboard EFS flash - i.e restore to factory.
