I'm having the same issue as well, I can't even start a print since the print head misses the lift by approximately 3 cm, during the calibration it works perfectly, but as soon as I try to star a print, it misses and sends the error that both print cores are at the same height.
I have updated to the latest and done every calibration and maintenance possible, this didn't happen before updating but can't find the previous firmware anywhere to revert the update.
Thanks in advance!
