Hi guys,i need your help with motors connection to my ramps 1.4
I found the motors phases and i connected the cables of the same phase in near pins on the board.
When I try to get the motor move in positive direction through pronterface it moves but when i hit the button for the negative direction it doesn't move and i need to reset the board to move the motors.Please help me.

Check wiring

[reprap.org]

Check Marlin config.h file for correct settings

Motor wiring should be ok if it moves +ve.

Have a look at the endstops & config for them. It will only go +ve & not -ve if they are 'activated'

It wont try to move below 0 position anyway.
