Y stepper has no current till print starts.
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?

Just to make sure, I checked the other motors as well, and it is indeed the SAME for X axis and the extruder as well. NONE of them gets current until the print starts. (X,Y and Extruder)
I then checked stepper timeout period, which is set to 360 seconds, as follows.

Also check in eeprom values. There you override the config value.
Thanks. Now that I know it is OK for motors to be "power less" before moves I am OK. (Did know if I had a problem or not.) The machine is fine, prints well and is well calibrated.
(I did go in eeprom and re-set value to 0, just to be sure)
In the end all is well and I thank you for your time. Much appreciated.
