Upgraded with X7 kit - issues with steppers
Posted: Sun May 21, 2017 5:18 pm
Installed the X7 kit on my Chinese K40 laser and powered everything up...I thought I got the stepper motors wired correctly, but they move in the opposite directions.
If it hit the RIGHT button on the keypad, the gantry moves left.
If it hit the LEFT button on the keypad, the gantry moves right.
If it hit the UP button on the keypad, the gantry moves down.
If it hit the DOWN button on the keypad, the gantry moves up.
So when it powers on, the gantry heads for the right-front corner and grinds against the stops instead of moving to the upper left and hitting the installed limit switches.
Each stepper motor has a red, blue, yellow and white wire. I matched it this way to the schematic posted in the instructions PDF-
Red -> A+
Blue -> A-
Yellow -> B+
White -> B-
Any ideas on what I might have done wrong?
Thanks
