Hi,

I have problem with RAMPS 1.4 and hot end. It is not getting hot enough only up to 160 degrees celcius. I wonder what is typical resistance of heater? I measured my heater resistance and it is 20 ohms. It sounds pretty high resistance?

This is my hotend: Hotend

Should I make heater Nichrome wire shorter?

It should be between 6 and 8 Ohm, so yes you need to make it shorter or use more than 12V.

Hi,

thanks for your answer. I did it and now it can reach requested temperatures.

Now I have some other problems. Just trying to figure out what they are...
