If you bought the ramps set from here the drivers are good to go. If not start by setting them at about .7V and check the stepper temps after some use. The default driver settings is 1.6V that is no good for the drivers or the steppers.

I set them to .7V. I had to set my meter to mVDC.

Do I need to update the firmware for the Arduino 2560? When it’s plugged into Repetier Host, I get the following in the logs:

No start signal detected – forcing start.
Communication timeout

The Arduino is a first for me. If there is a guide or explanation of what to do that would be great.
