Is your printer bed rotating?

What I noticed is that when i disconnect the 19V supply, the serial monitor shows a steady 0 from the pot iffz34n from A0. It sends sine wave: The thermistor 25W 5.

I am using the attached circuit to heat up the 3D printer bed. I am PWMing the pin 3 of the nano.

If you mean that the power resistor heater is not turning off, double check your wiring and the pinout of your MOSFET. Agree about the gate resistor.

Ok, once again, thanks for helping out an electrically challenged person. Normally the on-voltage will be about 3 times the threshold voltage being the point the ifz34n switches fully off. Also the sine wave code is something I found out on one of the forums that was used to demo a bulb going dim and bright slowly.

I need to study more. Here is the code, Code: As mentioned above, the schematic shows the MOSFET wired backwards, which can’t work the heater should be on all the time due to the body diode.

In between those two the device can be half-on, meaning it may dissipate lots of power and get very hot – the region of operation you want to avoid. I read serial values and can see that the pot is working. Screen Shot at I did connect a 10K irfz34b the gate to the ground.

So the heater can be on during reset until the pin 3 pinMode is executed in setup. If that is a problem, a 10K. The test code I used is here. But the thermistor isnt turning off. IRFZ34N getting too hot.

Is the attached looking any better? A thermistor is irfz34 type of variable resistor used to measure temperature. Please point out what you are calling a thermistor on your dattasheet. But when I connect the 19V, the values start floating wildly, and thats probably why the thermistor started smoking before I unplugged. I measured a 2. The behavior that you describe sounds like what jremington mentioned in reply 7. A better choice would be more like ohms, high enough to limit current but low enough to charge the input capacitance quickly as possible.

Triple check the wiring and post a circuit diagram hand drawn, not Fritzing.

But that didnt make a difference. This is one of many useful ones. Some people get confused by the threshold voltage – this is the voltage the device switches fully off, not on. Attached is the new circuit just a variation to my prev, this time using a pot. I tried at reducing the resistor from 10K to Ohm.

The gate resitor is way too high. The key specification is the value of Vgs quoted in the on-resistance section. MarkT Brattain Member Posts:
