Has anyone tried using a single resistor in the hot end? Seems that some of the RepRap type of hot-ends (J Head for instance) use a single resistor. I wonder if that would help moderate the temperature fluctuations of the head a little since there would not be so much power being pumped in so quickly.
cheers,
Michael

Re: Single resistor in hot-end?
I use the Newer Jhead. It does only have a single resistor.
I also use a Gen 6 board and in the Sprinter firmware, there is a setting that I reduce to keep the temp more constant. Only varies about 5 degrees C now instead of 30 to 40 when that setting was on full.
Full was 255. The settings I like are between 50 to 100. 100 is quicker to heat up and fluctuates a little more and 50 is pretty slow to heat up initially, but is pretty well on the money for accuracy after it gets to desired temp.
Here is the line to change.
//#define HEATER_CURRENT 255" to 50 instead of 255 in the Configuration.h file
That line was a quote in an email from Colin @ MakerFarm.
Works great.
