I've been using Repetier since 2016 on a homebuilt machine, running very well, using Unipolar steppers on my own driver boards.
Recently I decided to go with Bipolar steppers using Polulu A2988 directly on Ramps 1.4.
The machine runs well, prints very well, but I have no current going to the Y stepper when it is NOT in print. There is no "holding" current at switch-on, or whilst waiting for heaters to warm up, and at finish of the print. (Printing is no problem.)
Any ideas anybody?
