Heatbed Problems
August 06, 2014 12:36PM
Every electronic works for me, but my heat-bed. I have Arduino 2560 with ramps 1.4. Prusa i3. Extruder heats up perfectly, but the heat-bed stays at 0 and the LED won't light up. I know it is connected at the right place. Any suggestions will be appreciated. Thanks.

Do you see the bed temp in Pronterface when the "watch" box is checked? Even when not switched in it should show the room temp.
Also under "Settings" -> "Options" -> "user interface" check the "Display temperature gauges" box

Did you define the thermistor on the line:
Should be:
if there is a 100k thermistor

Is the #define MOTHERBOARD set at 33?

Thanks, but all of those settings are correct. I have noticed when I put in the pin in T1 on the board the temperature reads at 350 Celsius although the LED does not go on nor does the bed get hot. The printer is from 3DPrinterCzar if that helps.
