Hi, I just recently upgraded my Monoprice Maker Select v2 to a ramps 1.4 board because my melzi fried. I have been trying to upload the firmware but I'm consistently having this issue. I'm using the newest version of marlin as well as the arduino ide, and I've got ALMOST everything working, except my Y-Axis. When I first turn on my printer and hit 'Home' the Y homes, then the X, and then the Z. And they all work perfectly fine. But then if I go to start a print, or if I hit home again for any reason (ie level the bed and then re-home) it moves the bed a small amount (like 10mm) away from the min endstop, and then it doesn't move again. Or, if the bed is homed and resting against the min end-stop, and I shut it off, and restart it and hit 'Home' it drives the bed against the min endstop for quite some time, like it's searching for the endstop it is already resting against. I know it's firmware related because I have tried moving the x axis motor connector to the y axis motor spot on the board, in which case the problem moves to the X axis, and to eliminate my cable being the issue I completely replaced it as well and continue to have the same problem. I've also replaced the stepper driver on the Y-axis, to no avail. I am at my wit's end here, and would greatly appreciate if someone with fresh eyes could take a look at my configuration.H file and figure out the issue here. I have also attached a .Zip file with my entire configuration. If you can help me figure this out I will worship you as a god. Thanks for any advice!
