Re: Help replace dead hotend heater (Ohm's Law and Rated Wattage)

Correction:
225 should be ~23w and ~2amps.

Update:
I tried with the firmware output at 225 and when I send a print the PSU shuts down again. Took the output in the firmware down to 200 and it works without shutting down the PSU.
200 should be ~20w and ~1.9amps.

I will post an update when I connect a different PSU.

After reviewing I realized that the firmware does not modify the amps, right?. So the amperes remained equal. What is it changing? I checked the volts on the output and they were virtually 12volts (11.95). Let me re-check and report.
