Hey everyone
When you have the ramps connected to the pc, with just usb power.. and connected to Pronterface, and I asking the printer to move the x axis to the right 10mm, but it doesn't move??
Ramps board connects to pronterface with correct braud rate,. Says connected with no errors..

Now when I connect ramps to the power supply and ask x-axis to move it does.. Not connected to pc, just power supply, using firmware.

Also I read there supposed to be a red led when connected through usb, I don't get a red led..

You cannot run a ramps just off of usb.

USB only supplies 5v to logic side of board, steppers need 12v to move.
