Re: Is the 24v volcano heater block the correct match for the I3 MK3?



btw, if anyone wants to see the heater cartridge going through the heaterblock like it's a piece of cheese, look here:

Not all it appears to be; he is putting more than 100W into that heater block (19 Volt, 3.6 Ohm, 5.2Amp)

Peter

How do you know this Peter? Thx.

Ohm's Law. A 12v 40W heater has a resistance of 3.6 ohms. Therefore, when applying the 19v to the same 3.6 ohm resistance you get 100w.

And you can expect a somewhat shorter life of the component heater I would expect

No problem! I have been vaping for 10 years so I am intimately familiar with Ohm's law.

Oh, you will probably need to recompile the firmware and reduce #define Z_MAX_POS = <...> in the Configuration_prusa.h file by about 9mm (the volcano is 8.5mm longer than the v6).

No other modifications are needed, and after that firmware change, your MK3 will never even know the difference.

how doI recompile firmware? Im not an IT/ computer guy, so try and keep the explanations simple....
