Core One perpetual X-Y homing to front corner + Bed 115degC preheat cause over heat

Hello Prusa community , ex MK3 owner and new CoreOne Kit owner since 1 month

Fun built ! Printer going really good , already made 20+ prints ....but : 

--- random problem , some time the initial homing before print move X-Y in front corner and keep bumping both corner for ever ? why ? solution ? 

--- the initial bed heating say 115degC as setpoint (help chamber pre-heat?)  , and the homing problem cause bed over heat, wich require lots of time to lower it to the print setpoint = 60degC : where can i change that initial 115 setpoint to a print bed temp ? 

Printing since 2019 , Ex MK3s owner , current Core One owner

There is quite a long thread on this topic: https://forum.prusa3d.com/forum/prusa-core-one-hardware-firmware-and-software-help/constantly-recalibrating/

After reading though this and after implementing the recommendations if you still have issues then it's best to contact Prusa support over chat.
