thingiverse

2018/03/08 update still working great, no readjusting I found a working replacement for the heated bed thermistor. It reads 300k cold 18c The first test was 3 , 100k thermistors in series the bed ran about 110c-122c while printing. The second test was 4 , 100k thermistors in series the bed ran 75c-85c while printing. The last test was to have 3, 100k thermistors in series and also a 100k trim pot in series. While printing slowly adjusting it so that while printing to get a stable 88c to 95c while printing. They are positioned under the center of the bed. I wanted to do this because I was getting temps of 100c to 120c only in the center of the bed because the part being printed help keep in the heat only in the center. 100k thermistors http://a.co/aj6Jm3y 10A now with aluminum bed.
