Hello! assembled printer Mini G2 Pro (single extruder)

The extruder is heated to a set temperature. The motherboard connector under the power of the extruder is switched
  red diode.

If you turn on the hot bed, nothing happens. Indications temperature sensor does not grow. No indication diode.

The temperature sensor shows the room temperature

Help solve this problem. Thank you!

Hi! the connector fuse of the heated pads were not soldered at two points. I soldered and earned printer Thanks!

I bought Folger prusa i3 Rev B and have a problem with it.

My Heat bed will not heat up and the heat bed thermister reads Zero C which is impossible (should at least be room temp).
The resistence of the Heatbed is 1.8 Ohms and that of the thermister is 95K (both within working range).
Also, The voltage at the Ramps Blue socket where the wires to the Heat bed are connected read 0 volts. R Programming Training | DataStage Training | SQL Training

It seemed as thought that either the Ramps board is damaged or that the Repetier host software is either faulty or not configured properly. SAS Training | Android Training
I installed a new Ramps board but have the exact same symptoms. SharePoint Training
Any advice would be a great help

Hi,
I guess there has a open circuit on your heatbed thermistor.Have a double check on it.And refer the following info:

Check for the following errors
Fuse Damage
Electronics Damaged
Wrong Wiring
