inconel does exactly what nichrome does but doesn't expand and contract as much.

Might try that instead.

12V 40W works fine with my RAMPS
but I am using a 40amp power supply

OK
Search for 30W heater
like

heater cartridge produces 30W heat at 12V. It is suitable for hotends with a 6mm bore for the heating element.

Roughly 30 watts.

Use a cartridge heater

IMHO Resistors shouldn't be used as heaters!

Just a thought as my hotend failed in only 2 weeks. There's got to something better.

Why? In my experience the nichrome/fire cement design is more failure prone than the resistor.

I want to use nichrome wire to replace the heating resistor on the extruder. Does anybody know what gauge I should get?
