Title: Slaving steppers
Post by: GrandpawB on February 28, 2014, 12:21:11 AM

Could anyone here explain to me (a CNC router beginner) how to slave 2 steppers on the same axis ("Y") running one stepper reversed? (Thus both moving the gantry in the same direction.) I have 3 Geckodrive NEMA 23 steppers with a G540 control board.

Configure one of the motors as the A axis. Make sure all settings are the same as the Y axis motor.
Go to Config > Slave Axis, and slave A to Y.

To reverse one motors direction, either change the direction active low setting, or check the "Reverse" column in Config > Homing/Limits.
