I had my printer out of commission for about 3months last time I used it it worked fine. I decided to update the firmware install a bltouch sensor and made sure the steps match the old firmware. Now when I try to move the axis it moves forward fine but not in reverse. And I tried homing it using repetier and the smart controller and all axis move one step forward except the z axis it goes all the way down and won't accept the command from the sensor. All and stops works and not sure what else to tweak on the firmware.
