Geeetech I3 Pro B Home Function Not Working Properly(Fixed)

Post by Mikhail » Thu Mar 16, 2017 3:54 pm

I just got, and assembled the I3 Pro B and was going through the Pro&Pro B manual when I came across a problem with the home position key. When I press home, the x axis goes all the way to the endstop switch and stops as stated in the description, but the y and z axis only move about 5mm (in the wrong direction) and sometimes not at all. Afterwords I can manually move the stepper motors just fine except they (excluding the x axis) will assume their startup position as their 0 and won't let me move them behind their startup position back towards their endstop switches.

Manually, the motors move in the right direction, and I have tried reversing their direction in the firmware which only changes their direction, not how much they move. I have also tried updating the firmware to what's seen under the Getting Stared area of the GT2560 manual (http://www.geeetech.com/wiki/index.php/GT2560) minus changing the board size and steps per unit which I have left the same as before. I looked through the rest of the manual's suggested guides and couldn't find anything else that helped.

Did you check if you have all the endstops correctly connected?

Thanks, your solution worked after I rewired the endstops and uploaded the default firmware. When I was working on it I thought there was something wrong with the endstop wires because the manual showed this:
