CR10S5 - BTT SKR Mini E3 V3 + Sprite PRO extruder

Hi,
I’ve upgraded my CR10S5 with a BigTreeTech SKR Mini E3 V3 mother board and a Sprite Pro extruder on a 24V power supply.

All works fine EXCEPT i can’t make the sprite extruder heat !!!
If I asked it to heat the system reboot !!

Am I doing something wrong ?? Something not compatible ??

Thanks for you future help :wink:
