Hi All,

I am trying to connect BL Touch to RAMPS 1.6 without any luck. When i try to Jumper 5v and VCC pin ramps did not start and whole board was on sleep. If i remove the jumper then everything works fine. Did anyone face this issue. I really need BL Touch to work on my RAMPS 1.6 . Help me out.

Hi,

I have the exact same problem. When I use a jumper on 5V and VCC my RAMPS 1.6 turn off, and when I take the jumper off the RAMPS turn on.
Does anyone has a solution?

The 5v regulator on the mega is not very powerful
When you try power a servo with this it just wont work

you need to make your own 5v from 12v and power the 5v line from that
