[title] Verify Motor Direction
[* black] Before we try and home the printer we must verify the direction of the motors.
[* black] Go to the Gcode Console tab and send the command M18 to power off the motors.
[* black] Manually'''Manually position the X and Y axis to their midway positions by hand. This means the bed and the print head are in the middle of their travel distances. The Z axis should be raised about a hand width above the bed.bed.'''

[* black] Send G92 Z50 Y100 X100 which will force a verified axis position close enough for our test and allow us to command motor movement safely.
[* black] Go to the machine control tab and click on the X+1, Y+1, and Z+0.5 buttons one at a time. Verify that the motors move slightly in the expected direction. X+ should move the print head to the right. Y+ should move the bed towards the front. Z+ should raise the print head above the bed.
[* black] If the direction doesn’t match what you expect, you will need to go into Settings > System Editor and edit config.g, find the M569 command under the ;Drives section and change the S parameter of the drive in question. P0 = X, P1 = Y, P2 = Z
[* black] Changing a motor direction means you will also need to change the direction of the homing move for that axis by changing from a positive movement to a negative movement or vice versa. The homing files are found in the sys folder. Testing homing is covered next.
