Hello i just bought a DIY 3d printer kit!
I have buildt it and tried a gcode file without filament and everything is working fine! All motors run, endstops work and display etc is working just fine!
But the heated bed is not warming up and the hot end is not warming up!
Hotend: Temp says 50.9 (all temperatures are in celcius) and thats like 2x what the room temperature is!
Bed: The temp says 23.9 and 24 (just about right room temperature) BUT and none of the two are heating up!
I tried changing E_T and B_T to see if they changed and still only the bed temp works
Also its a DIY 3d printer kit Geeetech A8 so the temperatures only show for about 1 second before they both say DEF that means that one of the temperature sensors is not working!
So does the heated bed and the hotend not warm up because one of the thermos is not working? I have checked the connections like 1000 times and everything is where its supposed to be!
Here is some videos showing what i mean;:
Video showing when i start it up and what display looks like! (i have changed configuration now so it says DEF/180 and DEF/60 instead of DEF DEF)
Here is the heated bed soldering (looks fine for me)
Here is the mainboard when i turn it on:

Everything is brand new so should be working good!
