extruder temperature is offset by minus 10 degrees

Post by Anders_F » Fri Sep 16, 2016 2:58 am

Hello I just bought a Geeetech Aluminum Prusa I3 3D Printer kit with a Sanguinololu board. (http://www.geeetech.com/warehouse/index ... cts_id=609)

I Have got almost everything to work properly exept the temperature is offset by minus 10 degrees of my chosen temperature. for example if i set temp to 210C the extruder will heat to 200. And if i chose 180 it will heat to 170...

I have tried to replace hotend and temp sensor but its behaving in the same way so i dont think it is a hardwere.

The voltage input is 11.95 V

In Repetier-Host V1.6.0 there is a setting called Temperature offset in the print settings/extruder menu. I have tried to change that value from 0 (default value) to +10 and also to -10. But that doesnt change anything.

So I have tried to se if I could find something in the firmware (Plusa I3 A sanguinololu) that could fix the issue.

I have tried following changes without any succsess. (And i know im succesfully upploadnig frimware settings since i have changed max step limitation)

in configuration.h i have tried to change:

(173) #define MAX_REDUNDANT_TEMP_SENSOR_DIFF 10 (to 0 without any difference)

in configuration_adv.h i have tried to change:

(57) #define TEMP_SENSOR_AD595_OFFSET 0.0 (to 10 and -10 without any difference)

I need help to solve this problem since I cant find a solution to this problem. :geek:

Thanks Anders_F

Hi,
Your offset means the actual temp or the temp on LCD?
