I figured it out.

I have the make a jumper from the four pin 12v to the + on the hotend connector. Immediately the heatbed connector started working.

After more trouble shooting I have found the MOSFET on the hotend connector to be burnt out.

I'm am currently looking for a replacement.

I believe I should be able to repair both boards.

Hello,

I am having the same type of problems as "argus0209"

I have 2 Printrboards neither one will heat the hot end.
One has the same burned trace as his Utube video shows, and the other does not, but neither works.

I Have checked wiring and software.
Research suggests a short in hotend, wiring, or board.

Have you had any problems like this before??
Other functions controlled by this board are working.
I like the board design and want to get it to work.

Thanks for your help

Hi,
I also had a similar problem and fried 2 printrboard. Motors work fine, hotend also, but when I plug the heatbed it works for a few seconds and then both hotend and heatbed don't work anymore. So, then which is the best workaround? A 12V 10A relay? A potentiometer? Can you add the description of the workaround in the wiki? Thanks a lot.
