my extruder dont get warm

Hello,

I recived my printer yesterday and started test it out and didnt get it to stick on the bed.

Today i have bought hairspray and was going to try it out again, but now the extruder dont get heated up.

it says 22.4 deg. and bouncing up and down to 22.3 deg.

i have manually tried to set it to 190.... no luck.

i have tried to slice with the setting of 190 and press play... no luck

when i shut down and restart printer/computer the temp said around 40.5deg and started dropping.

What could possibly be wrong?

Same problem with heatbed.

I am in repetier and mac

 

can you move the motors or is it just the heaters that aren't working?

 

Dumb question: Did you switch it on? It kinda reacts (i.e. reports temperatures) without being switched on but you have to switch it on in order to send commands (like setting temperatures).

 

I restarted the computer and everything worked again. Bad software driver or connection.

 

I was able to move motors.

 

Check all your connections on the ramps board, it's possible a cable came unplugged.

 

Software sucks. Try using program called Cura

It connects every time.
Make sure u disconnect prepetier first so unlock the port (if connected)
