I just install my printer and when try Auto Home Y-Axis is going in the opposite direction. I manually push the enstop sensor and it is working well. X and Z axis are working perfect. I check the plug and wire colors are same as other motors.

Hi，if the motor can move at one direction only
1)Check the wires of the endstop 2)You need to check the endstop work or not：http://geeetech.com/forum/viewtopic.php?f=17&t=60927
3)Swap the a4988

I check the endstop and they are working correctly. They are open when axis are at middle and triggered when I manually push the endstop and check the signals.
What do you mean by swap a4998? The wires? Instead of black, red, green and blue change it for blue, green, red and black?

Hi, which means you can swap the X-axis and Y-axis drivers on the motherboard.

I try to swap drivers and it did not work. Y-Axis is moving away from the sensor during the Auto Home. But you give me an excellent idea, install the motor at the other side. I disassembly A11/A12 plates and invert everything to install the motor at the other side. Do auto home and it works perfect. Now I'm ready for fine tuning to start using my printer. Thanks for your help.

Change direction of motor Y at the firmware.

Best regards.
