Unable to get constant temperature control on my Sanguinololou (1 reply)

Hey All,

I recently brought a sain smart sanguinololu v1.3 a kit from amazon (Link

1. I uploaded the Marlin firmware after selecting motherboard as 62 in configuration.h file (This is the only change i made) - Downloaded from here (Link)
2. I could not get the motors to run
3. I changed to sprinter firmware (Again made necessary changes) - Downloaded from here - Now i got the motors working
4. In both the cases I found the temperature to increase rapidly and beyond the temperature set in repetier host. Eg: If i set the tempearture to 230C in repetier host, it would not stabilise reaching there, it would continue to increase rapidly. I also observed that the terminal for hot end/tip was constantly giving out 12.47V while the bed terminal was giving out 0V.

I am unable to get temperature under control. Can anyone help me on this ??

Btw i am using 100K thermistor. I can read the temperature correctly in repetier host.

Thanks
Rakshith
