No movement from motors, only humming

Greetings,
I received my robo3d, and i have run into the issue that motors wont move, i can heat up the extruder and turn on/off the fan, but when i try to move the extruder assemblu in manual mode all i get is a low humming.
no movement in X/Y/Z (ok which one is the bed?) at all, that does not move either.

I can move both the bed and the extruder manually.

I have not tried the extruder feed motor, i dont know how to do that?


Does anyone know what could be up?

It almost seems like the motors dont get enough power.

Mine also does that but when i use any of the home axis buttons everything is ok untill the next time i switch it on then have to use the home key again

 

Yes, you need to home it every time you turn it on. That's normal.

 

Thank you,
This did the trick, and the printer seems to be working from a mechanical standpoint, the only trouble now, is that the extruded material wont stick to the build plate.

I do have the ABS/PLA model, does that contain borosilicate glass on the build plate, it looks like glass thats on there, but im not sure.
