How do you get a 10W extruder up to extrusion temperature? On a cold day, I have trouble fully heating a 20W hot end.
If your total resistance is at 6-5 ohms then you should get 2 to 2.4 ohms. Voltage divided by resistance will give you amps. I have 2- 12 ohm 5 watt resisters in parallel that divides the resistance and gives me a total resistance of 6 ohms. That gets me about 2 amps and it heats really well. I suppose if you want more heat then drop your resistance down and you will get more amps/power. Be careful not to over drive the hotend power transistor on the board. let me know if that helps.
