on the jog control screen. The left button should make the spindle go left, right button it goes right. for X
up button the spindle goes to the back of the machine or away from you in y. down button it comes to the front of the machine.
Z up it should go up...... Z down it should go down. If any of these are backwards while jogging, you can change the DIR low active, or go to CONFIG Homing/Limits and change the setting in the reversed column for that axis.
You have to have these right first before a G code can run as expected.
