Another Dolly build - numerous issues - buzzing motors, no heat

Hi All,

I just finished building my “Dolly prusa MK2” clone, and was getting excited, however I have the following problems and I cannot find out what is going on, and pronterface is not great in helping this. I have downloaded and implemented the firmware from Tom “as is”, and havent changed anything.

All within pronterface:

  1. I am unable to get the temperatures returned.
  2. when trying to move the axis I get for Z and Y axis, a vibration noise and no movement.
  3. when trying to heat up the bed or the hotend, it states its going to heat them up but thats it. Even the LED I soldered on is failing to illuminate.

thats before I go onto the issues trying to enable the LCD…

Anyone have any ideas?
