Two stepper motors for one axis

[komar1970]

When you build a cnc router   with 2 ballscrew , Two stepper motors  for one Y axis
how do you wire the two stepper motors that drive the Y axis

 (cnc driver  gecko g540)

[Hood]

Usually you would use two drives and slave them in Mach.

slave them in Mach
can you explain more how to do it in MACH3

[Hood]

Config menu then Slave Axis.
Set the axis you want to slave as A, B or C  and then as long as screws, reduction, microstepping etc are the same you just tell Mach to slave A(or B or C) with Y and restart Mach and you are set.
