3.0.2 firmware has only positive Live Z adjustment

Hello all,

I just finished assembling the prusa i3 MK2 today. The original firmware on it was 3.0.0, which had live Z that worked as expected. It did not, however, appear to save at bootdown, so I installed 3.0.2. Now, when I go below zero, it simply returns to 9.999. It never reaches a negative number.

For now, I'm stalled, as the only way I can think to fix the Z (it is significantly "up") is to manually adjust, which I expect will cause yet more problems.

I guess things that might move me forward: How can I completely wipe the firmware? When I try to hold button when I hit reset, I simply get to choose language again, but all meaningful settings appear the same (high power mode, z live adjust)

Hi, I just release the 3.0.3

Do a factory reset by holding the rotary selector, pressing the reset and waiting for the beep. It is also covered in our manual.

Hi Josef,

Thank you for your help. That fixed it! Now negative Z is possible again.
