Has any one had issues with hetbed controler from main board not working but works from extruder connection on mainboard what does this mean has my main board had it only a new printer 3 half months old im yet to print anything decent on it
Could you please explain your problem in more detail.
If you open Repetier Host and connect, under manual control, turn on the heated bed. What happens?
What temperature are you trying to achieve. The standard power supply is only capable of heating the bed to approximately 60 deg C.
It would also be good to know what temp you are seeing before you turn it on?
