QU-BD Tuning

I’ve been tuning the QU-BD extruders to get them to be more reliable. What I’ve found is that they are extremely sensitive to temperature swings. I’ve made a temperature table for Marlin based on the supplied information by QU-BD. Here it is for reference.

#if (THERMISTORHEATER_0 == 61) || (THERMISTORHEATER_1 == 61) || (THERMISTORHEATER_2 == 61) || (THERMISTORBED == 61) // QU-BD
// Thermistor lookup table for Marlin
// ./createTemperatureLookup.py –rp=4700 –t1=25.0:100000.0 –t2=150.0:1783.0 –t3=250.0:232.0 –num-temps=36
const short temptable_61[][2] PROGMEM = {
{187, 350},
{212, 340},
{241, 330},
{275, 320},
{314, 310},
{361, 300},
{417, 290},
{483, 280},
{562, 270},
{657, 260},

The results of my current print at 212C are below.
