Resistor value
June 27, 2012 06:12PM
Hi everyone!
I need to change the resistor on my hotend. Looking around I saw that common value is 6.8 ohm 3w.
For such a small thing I don't want to buy it online (shipping is more than the object cost), but my problem is that I can find only resistors of 2w at the local electronic shop. There is the risk of burning the resistor?
Thanks for the help

Try it! It's a $1 chance to gain some experience, isn't it? The community will be interested to read the results.

The main requirement is that it is a vitreous enamel one so it can run at high temperatures and it has a good thermal connection to the heater block to prevent it overheating.
