Hi,
i am using ramps 1.4 with A4988 drivers. I am not using any jumpers for micro-stepping. I am also building the Kossel mini printer.
When i command the g28 command on PrinterFace to my printer, the stepper motors hum but do not go to their home positions. The motors have a lot of torque however they do not move. The endstops are all working correctly and i checked each driver and stepper motor individually and they all work. The wires are all connected correctly. When the power if off and i move the stepper motors they all make the Arduino light up. does anyone know that the problem is?
thanks!
