Does anyone know how I invert the axis in linuxcnc? Using the beta dual ballscrew on the Y so need to edit the hal or .ini to do it as the wizard doesn't support dual motors.

For twin screws you need Linuxcnc V 2.8 master if you want independent homing. I you want to reverse on of the motors then you can just swap the phases around on the motor.

What version are you using?
