Unit keeps shutting down


The heater cartridge broke while i was unclogging the nozzle so i replaced it with a 40w 12v unit of the internet. However i think that the power is too high as when the head and the bed are being heated the entire unit shuts down and restarts.
What is the power of the original heater? Or any suggestions?


Parts list is undocumented in the source repo - bar some commented notes in the readme.md ; I’ve requested a full BOM/Parts list before along with Gerbers/Kicad files for the PCB and connections.
