Hi,
I've been using my 3d printer for about 6 months, with the extruder heating up perfectly fine. Suddenly, it has stopped heating in the middle of prints, i checked the 5amp polyfuse and it was extremely hot. When it cooled down again, it was fine. Now it has been triggering very fast, which means heating up much faster than it ever did. I don't know what to do next, because everywhere, people are having trouble with the 11 amp fuse. Im using a 12v 15a power supply.
- Would it be wise to remove the fuse completely, and bridge the gap?
- If removing it is not a great option, then with what do i replace it? 5amp Polyfuses aren't available where I am.
- would it help if i attached some kind of resistor from the power supply to the main power input on RAMPS? (Just a random idea)
How can i fix this?
thanks
