Today I switched on and started to measure the circuit.

It switches on correctly and working except one thing. My original feeling unfortunately had been verified. The switch on voltage of the MOSFET I used (this one I found at home) is to high.

It switches on at 4.5-4.7V what is not really acceptable for the output of the Arduino inside the 3D Printer.

So I need to change the MOSFET to something else before I can continue.

I checked the datasheet of this one. It states that the Vgs threshold voltage should be in between 2 and 4 volts. :-(

But, I've the replacement type: IRLZ44N. This is definitely a logic compatible one. Hopefully during today I'll be able to pickup some.
