Hi, I'm using this variant:
[www.printedparts.nl]
It has a 6.8 Ohm resistor and a 100k Thermistor.
I have wrapped the resistor with alufoil, removed the metal ring and added a wooden plate between the aluminum block and the PTFE.
Also removed some of the black isolation gunk.
Heatbed doesn't reach 110 degrees celsius also by the way.
The heatbed is connected by using a relay that comes in between the heatbed on/off switch on the Sanguinololu and the 12v PSU and should be heating fine, but doesn't. Maxes out at around 87 degrees celsius.
Why the hotend takes so long to heat up and then drops a lot in temperature... no idea. I have also added a insulated wall on the left side and backside of the printer, and I have insulating foam underneath the heatbed and underneath and on the sides of the printer area to prevent some draft and cold radiation.
Also did run the M303 setting again with S = 210 and input the Kp Ki Kd values in the firmware and reuploaded again.
I measured the current and voltage:
10.5 V * 1.6 A = 16,8 W
